First Impressions

The verykool s5511 Juno Quatro comes packaged in a compact box with a backdrop of clouds in the sky along with the Juno Quatro in the foreground.  Simple yet effective in standing out.  The backside is empty aside from the security seals preventing the box from being tampered with. 

Brief features and specifications are located on the side of the box which describe more features including an expandable microSD card slot for up to 32GB of extra storage, a rear facing 8MP camera with LED flash, 2MP front facing camera, and FM radio tuner support.  The only bit of information that seems missing on the box is the capacity of the battery.  If you don't look at the specifications on the verykool website you wouldn't know its listed as 2300mAh.

Looking at the full round of specifications is making the Juno Quatro look like quite the package for an affordable price.  We'll see how this translates in real world performance usage.

There's one bit of information that has managed to stay hidden though, and that's regarding the 1.3GHz Quad Core CPU, particularly what kind of CPU is being utilized by verykool for this model, but I have an idea just by looking at the FM radio support and at this price range.  I'm going to guess its sporting a MediaTek processor, I just don't what kind at this point until I use the s5511 Juno Quatro. 

But as it stands, the 1.3GHz Quad Core processor in the Juno Quatro should be more than enough to have you be able to do such things as web browsing, email, texting, YouTube, music playback, Google Maps, Skype, voice recording, calendar, camera and video, general video playback, Facebook, Twitter, and make phone calls. 

With only 1GB and likely a budget MediaTek Quad Core 1.3GHz processor, I'm not going to say you will be able to do everything comfortably with ease, but you should be able to get just about everything you need out of such a CPU, maybe with some minor lag or delay at some point.  The only thing I'm not hopeful about is games, more or likely if you play games such as Angry Birds, Dots, Fruit Ninja you will be okay, but anything graphically 3D intensive such as Need for Speed or Republique, NBA, GTA, Asphalt you are more likely going to experience lag and it's not going to be a great experience.  MediaTek CPU's are known to have weak GPUs compared to the competition.  But then again a factor of 3D gaming performance is the screen resolution.

The Juno Quatro makes use of a qHD 5.5" IPS capacitive touch screen display.  It's a big display so you have lots of real estate and it'll be great for people who need access to larger text and buttons, but to be honest this is 2015 and qHD (quarter HD) or 960 x 540 resolution is getting outdated and very fast.  200ppi of pixel density is nothing to get excited about as there are other budget phones out there that have a 720p (1280 x 720) resolution, that should and is the standard going forward especially for this 5.5" screen size.  However, verykool may have chosen qHD for the reason of knowing that the GPU (graphics processing unit) is weak on this model.  Having a higher resolution screen makes your GPU work harder because it has to push and render more pixels and therefore 3D graphic programs will run slower.  Having a lower resolution screen helps your GPU work easier and 3D graphics will run quicker.  That compromise is very likely the reason why verykool have chosen the qHD resolution screen.  So you may be able to play more 3D games than I envisioned because of the lower screen resolution.

In terms of display quality, the verykool should do well in this regard as it has an IPS display which promises to offer rich color and extra wide viewing angles associated compared to a non IPS display. However, that's all theory and it isn't specified what manufacture the IPS display in the Juno Quatro comes from.  Also the screen is not an OGS (One Glass Solution) which would have reduced the thickness of the display even further by removing the layer between your touch screen and display.

The verykool s5511 Juno Quatro is offered in an assortment of colors including fuchsia, green, red, blue, and yellow.

The verykool s5511 Juno Quatro comes bundled with easily the best bundles I've seen for a Smartphone.  In the box were the following items...

  • verykool s5511 Juno Quatro Smartphone
  • 2300mAh Lithium Polymer Battery
  • Two Screen Protectors (1 pre-applied, 1 extra)
  • Micro USB Cable
  • USB 5V/1A Wall Charger (UL Listed)
  • Extra backing plate Smartphone cover (Black color)
  • In-ear Canalphones with integrated microphone
  • Small microfiber cleaning cloth
  • Manual

I've never seen an extra backing plate cover come with any Smartphone I've had before.  The model being reviewed today is the fuchsia color, however, the extra backing plate cover is a black color.  This is great as you can have a male use the black color backing plate cover, or a female use the fuchsia backing plate cover.  About the only item missing here would have been a protective case.

Visual Overview & Quick Use Findings


The verykool s5511 Juno Quatro is constructed out of purely plastic to keep the cost down, no surprises here.  What is surprising is that it feels generally solid without any weird creaking noises when you move it around with your hands.  Plastic isn't bad if done right, and this one appears to be built well considering the price.   One good thing about plastic is that it keeps weight down.

According to my digital scale, a naked Juno Quatro weighs 157 grams or 0.347lbs, with the battery inside.   

The verykool s5511 Juno Quatro feels tough enough to withstand normal usage, but not sure how it will do in a drop though. It's not a tank but it should withstand some light shock and impact.  It would have been amazing if verykool bundled a silicone gel case or some sort of protective case for the Juno Quatro because there's very little accessories you can purchase for this phone.

The screen is semi glossy compared to other phones I've seen.  The body being made of all plastic construction has a very smooth matte white finish without any texture or grip.  After extended usage the phone becomes slippery in the hand is also a fingerprint magnet.  I noticed on the fuchsia back plate cover that its paint job has some little flakes on it but very minor.  The color really pops out as you can see in the photos, it definitely stands out from the crowd.

A screen protector is placed on the device from the factory, while another extra screen protector is provided in the box, for use at a later time, which is always a welcome. 

Just to nitpick, the pre-applied screen protector contains a few small air bubbles near the top left of the screen and around the sensors, but it's easy to forget it's there when using the phone. 

Looking at the front of the verykool s5511 Juno Quatro Smartphone, we find a simple yet nice looking phone with curvy rounded edges and a very small 3.0mm bezel.  Phones with thick bezels look ugly.  Equally impressive is the thickness of the Juno Quatro measuring in at a relatively slim 8.5mm or 0.334" making it considerably slimmer than my old Newman NM890 Chinese Smartphone (10.15mm or 0.399") and even thinner than the new Ulefone Be One Smartphone (8.8mm or 0.346") I just reviewed.

There are three capacitive touch buttons at the bottom of the screen, three symbols for the menu key, home key, and back key.  Unfortunately more compromise needed to be made to drive cost down, the capacitive touch buttons are not back illuminated.  Therefore you are out of luck at night as you won't be able to see them at all, you must remember the location and which buttons do what specific function.  Depending on how the sunlight reflects off the Smartphone determines whether or not the symbols brighten up or not.   

Turning over to the backside we find a small hint of flair in the metal ring around the rear camera lens.  Beside the camera lens we have a single LED flash which is surprisingly bright under usage.  You have to download a flash app as there is none pre-installed.  Towards the bottom is the verykool logo and speaker grille port design.

In terms of ergonomics and handling of the Juno Quatro in the hands while taking a photo, I usually hold Smartphone's on the four corners with my thumb and index fingers.  But in this case, and how the camera lens is positioned, I need to be careful that my other fingers don't cover the camera.  Some other phones have the camera positioned a bit downward from the top so this doesn't happen, but this Juno Quatro rear camera sits directly at the top.  Just something minor to get used to.

People with small hands will not be able to reach across the real estate of the screen. You need two hands to fully operate the Juno Quatro's large 5.5" screen.  In the end you need to make the necessary adjustments if you have small hands.  If you have large hands like a basketball player, that's a different story. 

The qHD IPS display isn't the best screen I've seen, however, it's also not the worse screen out there.  I would rate the screen as below average overall in performance and average for touch screen usage.  It has just enough pixel density at 200ppi to get away at being decent in terms of sharpness.  You can indeed see pixels, however, it's not nearly as bad as I thought it would be, it's very manageable and screen resolution even at this size of 5.5" looks decent.  I'm sure if this wasn't an IPS display things would have looked worse.  As it stands, even though I can notice pixels on the screen, and notice how the icons are lower resolution and not as sharp as that of 720p displays, things are still very manageable and look good.  Text is generally smooth and easy to read, icons are a little softer than usual but it's all decent and doesn't take away from the performance of the Smartphone.  It's a fair compromise for an affordable Smartphone. 

The negative aspect of this qHD IPS screen is that it exhibits certain things that don't happen on better IPS screens I've seen in the past.  The screen color cast is a little more cooler and not truly 100% white, the white balance could have been better.  It has a slight blue cast.  The screen also exhibits a small bit of backlight bleeding at the lower edges of the display when the brightness is cranked high.

Another negative of this qHD IPS screen on the verykool s5511 Juno Quatro is that the IPS screen viewing angles aren't nearly as good as other IPS screens I've seen.  I don't know if it has anything to do with the screen being semi-glossy and lacking OGS, however, I suspect this plays a role in the viewing angles being below what good IPS displays should exhibit.  If you are looking at the screen straight dead center, the colors and image looks clear, but as soon as you tilt it toward another direction, the screen color begins to shift, sort of like what you get with an all LCD display.  The colors get darker and a blue tinge appears on the screen.  If you compare the screen to the LG IPS OGS screen on the Ulefone Be One Smartphone I just reviewed recently, the difference is night and day difference.

Display brightness isn't all that bright overall, it struggles outside in sunlight and for example when you are trying to take a camera photo, you struggle to see what is being displayed on screen, all you end up seeing is shadows while you do your best to put the subject into the frame.

Touch screen sensitivity with the verykool s5511 is average at best.  The screen requires you to use moderate force to execute touch commands.  And sometimes with certain parts of the screen, usually toward the bottom of the screen, you have to press harder.  So weird things can happen sometimes, for example, let's say you start swiping from menu to menu, sometimes the touch screen enters a menu you never wanted to enter, because you didn't push the screen hard enough while swiping.  Or you end up entering an app you never wanted while swiping across the apps menu.  Good news is that I noticed no phantom ghost touches, so there's nothing wrong with the hardware, it's just the sensitivity is lacking. 

The same moderate force is needed while operating the capacitive touch buttons below the IPS display.  Those three menu key, home key, and back key requires you to press down harder than usual to register the command.

Android Operating System - 4.4.2 Kit Kat

verykool s5511 Juno Quatro features the already mature Android 4.4.2 Kit Kat mobile operating system.  I remember Android 4.2.2 Jelly Bean from my Samsung Galaxy Smartphone reviews and this is not that much different, the transition is very easy to Kit Kat.  Kit Kat improves further on an already mature ecosystem. 

On the verykool s5511 Juno Quatro I did not have any weird issues such as crashes or restarts that related to the actual operating system, it's been stable and reliable for the most part.  

When I say for the most part, the issue I had was related to the battery and what was being recorded by the OS battery indicator.  In Kit Kat there's an option to turn on the battery percentage indicator so you can see a numerical value.  So 100% down to 1%. 

Well initially I thought the verykool s5511 Juno Quatro had insane battery life.  The percentage was declining very slowly and this was during when I was running tests on the phone.  I turned on every setting such as Bluetooth, Wi-Fi, GPS, FM Radio, flashlight, ran 3D benchmarks, and the battery indicator was declining very slowly, it tricked me into believing it had tremendous battery life.  Then when I hit 54% battery life, the phone rebooted, then blacked out completely.  I couldn't turn it back on until I hooked it up to the charger.  Turned it back on and then I see the low battery life indicator telling me the phone battery was running low, the numerical value was 1%.  So it jumped from 54% down to 1% in a matter of seconds.  Basically the battery indicator would consistently offer inaccurate readings.  What a weird problem, however, after reading online it appears other people have had the same issues with different phones, so it's not an isolated issue.  It was funny as I've never come across this issue with any of my other phones.  Could be related to the battery or truly an OS glitch. 

It should be noted that with the verykool s5511 Juno Quatro, the Android 4.4.2 Kit Kat operating system is very slim and not bloated with useless app's, always appreciated.  There are pre-loaded apps including Facebook, Google Hangouts, Skype, Twitter, WPS Office, and a verykool app, however, the rest is all stock Android without customizations aside from the icon design.

Some phone makers run their own customizations or skins, such as TouchWiz for Samsung, Sense for HTC, or Xperia UI for Sony, but there's nothing like that on the verykool Juno Quatro and I like it this way, being slim and without bloat.  The Juno Quatro surprisingly had generally snappy performance between the apps menu.  Some lag experienced sliding around against widgets and wallpaper background, but in general its quick.  I think the compromise of a qHD screen did help pay off in letting the phone not render as many pixels as 720p would require.  This lets the graphical performance feel speedy navigating through the OS. 

I like that the Juno Quatro has the feature called 'Scheduled power on & off' in the Settings menu, very straightforward and great for saving extra battery power when you're in bed.  It's been offered for a while on Android 4 but on some phones it's not there.   Check the gallery below for OS screen shots and benchmark screen shots displaying the performance of the verykool s5511 Juno Quatro.


The verykool s5511 Juno Quatro - Any good?

After using the verykool s5511 Juno Quatro, I would like to be up front and say that the Juno Quatro has more disadvantages.  For the price the Smartphone is being sold at currently, it definitely feels overpriced for what you are getting in return.  You'll find out these disadvantages shortly.  In the end, the verykool s5511 Juno Quatro feels $50-60 too expensive.  This phone should definitely be priced well under $100 USD to be honest, especially in today's market.

After digging into the phone, I found out that the verykool s5511 Juno Quatro is sporting a MediaTek MTK6582 1.3GHz Quad Core CPU with a Mali-400 MP GPU.  This is a low power and highly efficient ARM Cortex-A7 based processor released in Q3 of 2013 so it has been out for a while now and remains the low budget model in the MediaTek product lineup.

For my needs the verykool s5511 Juno Quatro is not quite up to my standards, however, that is not to say it's a bad phone.  Different strokes for different folks.  I like to play 3D intensive games and the Juno Quatro isn't powerful enough for games that I like to play.  Running one instance of 3DMark benchmark will showcase to you immediately. 

It can handle less intensive games such as Angry Birds, but struggles for others.  You can play Hutch Games Smash Bandits generally well but with bits of lag especially when there's lots of carnage on screen. 

For being used as a phone, with occasional surfing on the Internet, YouTube, music listening, FM radio, Google Maps Street View, Email, texting, voice recording, Calendar usage, the Juno Quatro is more than fit to do those things with relative quickness.  It's more than capable.  Some intensive programs may require an extra second or two to get going but it all works in the end without too much fuss. If you are a power user, you can look elsewhere. 

Performance - Benchmark Results

We suggest you take a look through the gallery above to see all the results from the Juno Quatro and their breakdown, however, here are some of the scores below from various Benchmark apps.

  • GPU Bench 3D: 12,555 points (Screen resolution normalized score 6,509 points) (avg: 48.10fps/highest: 75.06fps/lowest: 28.45fps)

Browsing & Multimedia

The verykool s5511 Juno Quatro is capable of connecting wirelessly to any 802.11 B/G/N network, however, doesn't have support for the latest AC standard, not really a big deal in my opinion.  I did not have any issues connecting to wireless networks with or without a password, I've had this trouble on some phones in the past. 

However, the Juno Quatro's wireless antenna has consistently weaker signal strength compared to my older Chinese Smartphone, the Newman NM890.  It's consistently 1 to 2 bars weaker than my other Smartphones in general (HTC 8X, Ulefone Be One, Newman NM890).

The same news can be said for the signal strength of the antenna that connects to the cell phone carriers network, it's consistently weaker as well getting 1 bar in general less than what my other phones see.  If outdoors then the reception is considerably better, unless I'm in an area with known spotty service.

Call quality is decent with good volume.  The internal speaker is loud as well however will distort at the highest volumes.  You can feel the phone vibrating because of the distortion when the speaker is at the max levels.

The built-in Android Browser is compatible with just about every website and renders them without any issues.  With the qHD screen, the text isn't as easily legible as with a 720p screen so you have to zoom closer to read small fine text. 

In terms of lag within the Android Browser, yes there is some lag and unresponsive/choppiness/stuttering while the webpage is being loaded initially, any attempts to scroll down and up will cause some delay, choppiness, and stuttering until the page fully loads.  After its finished fully loading, scrolling up and down is smooth and quick.  This happens with most Android phones on the market.

Speaking about RAM, for Internet browsing I tend to leave a lot of pages open in tabs and go back and forth between them, just a habit.  At times I did feel having more RAM would help, at least an extra gigabyte, to prevent the constant reloading of pages.  I notice less of the reloading when using an S4 for example with its 2GB of RAM. 

Browsing along website's, you can cut, copy, paste like you can do on your desktop machine. You can save web pages to view offline at a later time as well with the integrated browser, this feature has been on Android Browser for a while now.

Play Store is installed by default on the verykool s5511 Juno Quatro, so you can enjoy thousands of app's, games, books, movies, music.  Play Store has come a long way and is just as great as the Apple App Store.

The verykool s5511 Juno Quatro is powerful enough to be used as a standalone movie playing machine, however, you will have to settle with qHD resolution.  I could play just about any file container out of the box, and more with a separate video player such as MX Player.  I could play 720p videos with the Juno Quatro but why would you want to with a qHD screen, doesn't make sense.  Videos still look relative nice if you aren't too picky about noticing individual pixels.   

Audio Quality - Any Good?

Sound quality when using earphones or headphones with the verykool s5511 Juno Quatro is the best way to go.  This is one aspect of where the Juno Quatro excels, it has decent sound quality when paired with good headphones.  I'm surprised that with the Doogee DG350 having the same MediaTek 6582 CPU, it should technically have the same audio chip no?  Well with the Juno Quatro, the sound quality is significantly better than the tiny flat pancake sound coming from the Doogee DG350.  The sound quality of the verykool s5511 Juno Quatro is miles better with decent bass, clear vibrancy, and general music fidelity.  Listening to the FM Radio sounds very nice as well.

8-Megapixel Rear Camera - Any Good?  What about the 2-Megapixel Front Camera?

This is where the real disappointment begins.  I won't spend too much time here and I'll let the photos and videos speak for themselves.  But what should I say regarding the camera?

The worse ever camera on a modern day Smartphone I've tested so far belongs to the Doogee DG350 I reviewed not too long ago.  Remember how I said that the Doogee DG350 had cringe worthy photos that looked like seeing through a foggy window?  Well I don't know how, but the verykool s5511 Juno Quatro  manages to achieve worse photos. 

No specifications are given to what kind of camera sensor is used for the Smartphone and for likely good reason.  They are so bad it's not even funny.  It's clearly interpolated, clearly heavily compressed looking at the small file sizes (8MP files ranging from 550KB - 1.1MB), and everything about them are horrendous.  Weird colors, bad auto white balance, bad autofocus, this is worse than looking through a foggy window.  Forget using Skype or Instagram with the verykool s5511 Juno Quatro.

What a strange camera indeed.  I will explain it this way... 

The rear 8MP camera on the verykool s5511 Juno Quatro is exactly if you were to wear reading eyeglasses.  Everything up close looks good with them on, however, continue using those reading eyeglasses for your distance vision and see what happens...everything becomes blurry and you can't see anything.  You're effectively blind when you wear reading eyeglasses for distance vision, because they are meant only for close distances.  This is exactly the same case with the 8MP camera on the verykool s5511 Juno Quatro.

The rear camera takes fairly decent (still below average) close up photos.  However, anything shot at normal to long distance is simply flat out blurry.  What an interesting camera lens unit they chose to use on the verykool s5511 Juno Quatro.  It basically has reading eyeglasses for its camera lens.  You are regulated to only taking macro close up photos if you want a half decent photo.  The same effect is seen in the 720p HD video recordings. 

The front facing 2MP camera isn't anything worthy to write about as well, however, it does not exhibit the same madness as the rear 8MP camera.  The lens focal length is wide enough that you can fit two people in a selfie photo which is a good thing.  However, photo quality is not good, it's as good as a cheap web camera.

Original Test Images & Video Samples


Battery Life

This is a very important area for most customers because they don't want to be charging their phones all day long.  The verykool s5511 Juno Quatro has a fairly large 2300mAh battery.

With moderate usage consisting of movie playback, YouTube, GPS, Music, Internet Browsing, Video Recording, 3D game playback, I managed to get around over 18 hours.  If I used the Juno Quatro sparingly, I easily see over 1 day of battery life.  If I used the Juno Quatro constantly at highest brightness, ran loops of 3D benchmarks, used the LED flashlight, FM radio, music, Bluetooth and turned everything on, battery life drastically drained in a couple of hours (single digit).


If you require a Smartphone with fast lock on GPS and use GPS frequently, the best thing would be looking at Smartphone with a Qualcomm Snapdragon SOC.  The GPS units inside Qualcomm SOC's are so much better because of GLONASS support and they are generally much faster than MediaTek. 

MediaTek has always had problems with their GPS out of the box, their GPS units just are not the best. I've never had a MediaTek device with working GPS out of the box, it was only until I had to fix it that it worked.  I'm sure they work better in Asia, but you always have to tweak and fiddle around with either EPO settings on MediaTek devices or delve into the MediaTek Engineering Mode and fiddle around with A-GPS and EPO modes.  MediaTek uses A-GPS (Assisted GPS) that needs the latest EPO (Extended Prediction Orbit) files to help the device locate GPS satellites. Qualcomm uses a different system with GLONASS and its so much better.

Out of the box the verykool s5511 Juno Quatro's GPS did not work for me, and since the Juno Quatro is not rooted, I didn't have a way to root the phone as of yet.  On my Chinese Newman NM890, I had to fix GPS by rooting the phone and then downloading an app that allowed me to automatically download the EPO files. 

However, since there doesn't seem to be a way yet to root the verykool s5511 Juno Quatro, I thought I was out of luck.  Luckily after many hours of fiddling around, I found an app that let me get inside MediaTek's Engineering Mode in the phone and thoughI have no exact clue what I did to get GPS working, I got GPS working. 

It seemed that by going to MTK Settings Mode ---> Location ----> Location Based Service ---> YGPS ---> Information sub tab and pressing AGPS restart, and then heading back to Location ----> Location Based Service ---> AGPS sub tab, change A-GPS mode from MSB to Standalone.  Then head to EPO sub tab and hit EPO (Download).  Head back to AGPS sub tab again and change A-GPS mode back to MSB.

After that, the GPS on the verykool s5511 Juno Quatro started working for me.  But I noticed that the Juno Quatro consistently picked up less GPS satellites than my other Smartphones.  Seems like every antenna in this phone is weaker than other phones.  After about 60 seconds it started picking up and locking on GPS satellites, and got quicker thereafter.  It should be noted that on most Qualcomm based phones, GPS is picked up within a few seconds, much faster.   I hear the newer MediaTek SoC such as their 64-bit offerings are significantly improved and have GLONASS support.

verykool s5511 Juno Quatro

The verykool s5511 Juno Quatro ends up being a mixed bag.  It has positive attributes but it also has negative ones that affects user experience in a big way, most notably the camera quality. Though if you are not the person that does a lot of camera photo business, then the verykool s5511 Juno Quatro is fairly decent and will certainly get the job done.  For being used for such tasks like phone calling with HSPA+ support, Internet browsing, YouTube, music, FM radio, Google Maps with Street View, Email, texting, voice recording, Calendar usage, the Juno Quatro is more than fit to do those things.  Because of the displays qHD resolution, it allows the user experience within the Android KitKat operating system to be generally snappy and smooth, only with some lag or slowdown here and there.  Take the camera out of the equation and the Juno Quatro is fairly decent.

Sound quality is quite enjoyable through the audio jack and the FM Radio function sounds great when you're on the go.  But if you're a power user, or into intensive 3D games, want usable cameras that are decent, want a steady GPS signal, want better network coverage and Wi-Fi signals, look elsewhere.  We also saw inaccuracies of the battery life indicator that made the phone appear to have better battery life than it actually has.  

For how the verykool s5511 Juno Quatro performs as a whole package, it's clearly overpriced and misses the mark.
