This thread is ONLY a review of the Star S9500!
The Support topic is here:

The Review​
The Star S9500 call me to attention because of the Quad Core processor and the 12.6MP camera only with 123€!
In that time I was searching for a new phone, but I won't spend more money than 150€. So I searched a bit, and I wont buy some phone in Portugal because of the low specs at the same price. I was looking to an SmartPhone that I could play great games at low price and with long battery life.
I saw the specs of the Star S9500, and I saw that included MTK6589 1.2GHz x4 processor with a great camera, large display and the 2800mAh battery, which for me was a great buy.
In some reviews of the Star cellphones the general people said that they have an overall good quality. So I bought this phone.
The problem started here: I waited for 3 months to receive the phone! It isn't GeekBuying's fault at all, was my country's customs. I had to pay an extra fee (35€) for the S9500. That wasn't a problem, it was very cheeper than any phone here.
I don't have the box in this city (I received in my holydays), so I can't show some pictures. But here is a picture from the GeekBuying's website:

It came with quite good Earphones (if you enable Bass Boost it has great quality for stock phones), with a average quality USB cable, an EU USB charger, two 2800mAh batteries and this case, which it seems to be good quality:
I turned it on with my SIM card, and it was easy to configure. Even the 3G network is configured. The MMS service is configured, but I don't know why it isn't working, but I don't bother with that.
There is some pictures taken in my home:
​
Don't focus on the GeekBuying's AnTuTu score! The real score is this, which is average, as I installed all my apps and I removed the china apps with MTKDroidTools (I will teach in the support topic):
​
It doesn't compare to an Quad Core Cortex-A9, but it is quite good for a Cortex-A7.
The screen resolution helps to the performance. As it is only FWVGA instead of HD, it has a difference of 1000 points, and some FPS improvements in general gaming, as if you change the resolution to 720p in Star S9500 it only decreases 500 points, as I will show later.
As you can see, the front camera is 4.9MP instead of 2MP as claimed in the GeekBuying.
It is very smooth. The battery gets drown if you play more than 12h of Real Racing without stopping, and it can last 2-3 days only with SMS and net browsing, and that makes me satisfied.
The bad point is the ROM. It only has 4GB of rom, which you only can use 1.5GB of them for internal storage and 1GB for apps, and the rest for system. That can be solved with a 32GB Micro SD Class 10 card, which I would buy from 22€.
NOTE: The camera came pre-set at 8MP, but in the camera options you can change to 12.6MP, as I will show in support topic!
Here is two pictures with the rear camera, one at day light (1,16MB) and other at night with flashlight (2,29MB):
​
I didn't take any pictures with the front camera, but I used it many times to do video calls from Skype and it has very good quality has expected for a 5MP camera.
Now about the apps. If you don't remove the china apps, it will appear a folder called mtklog in the internal memory that will be raising the size minute after minute, only with system logs until you run out of space! It's secure to remove, but it will appear in less than an hour.
After I solve all my problems with the phone, I can see that I have a good product, but without any support.
You can post here questions about the phone!
I will create a topic for support for the Star S9500, but you can do questions while it isn't created!​
Best regards,
Ivan Santos.

Malware on S9500 at time of shipment!
Hello, I bought my S9500 in Dec-2013. I installed AVG and was immediately warned that OperaService was malware. I thought this cannot be true and ignored the warning. Recently it has been reported that the Star N9500 has been proven to ship with Malware. I have been in touch with G-Data (the company that reported on the N9500), they are almost certain that my phone, S9500 was shipped with Malware installed at the factory.
Bummer, it is a great phone for the money.
So, I got my money back from Amazon, and I think I get to keep the phone. Score!!!
My question (note that I'm new to digging into phones).
If I root the phone, will I be able to remove the OperaService (cannot remove it right now as phone is NOT rooted). I don't care about support anymore, that has obviously gone...
I understand that I may ruin the phone. But with advice from the Forum, I hope to keep it at give it to my daughter.
FYI, I replaced the S9500 with a Nexus 5. Wow, what a great device.

HEllo, just the 3 most important points on chinaphones:
1-Flash Led Power (Compare with another phone if you can, a samsung, an iphone or eben a huawey)
2-Loudspeaker for music/handfree phonecalls
3-GPS (maybe after a root and GPSFix, since 99%of chinaphones are setted on chinese GPS server)
Thank you very much.
I should add that now that you can find a Samsung 3 Neo for €170 I don't know if I would pay more than €100 for this phone

Comparative Review: Mijue M10, first under-USD150 8-core Smartphone Vs. Cubot X6

The good: USD150 is a very acceptable price for Chinese phone with mainstream chipset. Mijue M10 is as fast and smooth as Cubot X6. Display is good with more details.
The bad: Though I’ve saw lower-than-mediocre back cameras like Cubot X6’s, the M10 is even worse, which, however, has a better front camera. Money on useless and crap gesture sensing should’ve been saved or used to enhance other features.
Bottom Line: Mijue M10 did not surprise me finally by functioning, but it has a right price.
The cheapest 8-core Chinese smartphone was USD40 cheaper in about 2 months, and now we see Mijue, a never-heard brand, make a debut with its M10 for USD150 or so. The M10 and Cubot X6 (USD190) share the same components except that the Mijue handset has a smaller Nand flash memory. According to a friend of mine on the sourcing market, 8Gb makes a price gap of approximately USD 5, which doubles on retail.
It seems that an overall markdown of USD30 dollars in MTK6592 mobile phones is destined for now or the few months to come. Before making that sure, we should figure out whether Mijue M10 is a normal phone or it’s priced low for reasons, because a crap, however cheap it is, is a crap.
The performance of Cubot X6 proves that the collaboration of MTK6592 Octa-core CPU plus a 4-core Mali-450 GPU well powers a 720p-display smartphone (http://forum.xda-developers.com/showthread.php?t=2647933). Huawei Honor 3X, with the similar components, is fantastically better.
And now, I’m showing you what a phone Mijue M10 is by comparison with Cubot X6 bit by bit.
1. What the hell?
The M10 is equipped with a gesture sensor, which is useless from my point of view. What’s more, it takes great efforts to keep your palm neither too close to nor too far from the screen when you make “air” gesture – I mean you have to nearly touch the screen but not really touch it.
Sometimes, people don’t appreciate the existence of something or grieve on the loss of it even if it was perfect by itself. The first rule of making a cheap phone is not to add such an embarrasing burden on it, so you can save money for something else that people really cares, for example, a good look.
Cubot X6, which costs you USD40 dollars more, has no fancy to flaunt, but is good as a common boy.
2. Design.
If someone had only half an hour to design a cellphone and no afflatus flashed through his mind, he would bring out Mijue M10. In fact, this Mijue handset is that kind of stuff you think is the copy of something at first sight even if you can’t recall which one. Just as you may guess “s/he should have committed suicidal many years ago” when the poster of Marilyn Manson leaps to your eyes, for no special reason.
However, the Chinese producer didn’t do anything stupid like leaving wide seams on the body or many physical buttons on the edge. Besides, the phone is thin and its matte-finish back cover is not cheesy, so generally it’s a neat phone without much to complain about.
Now Cubot X6 looks far more inspiring. Its copy of Arc S can be taken as a tribute to the past and the aluminum bordering the camera lens is, anyway, unique.
3. Display
To my surprise, Mijue M10 is equipped with a better display than Cubot X6 in terms of both resolution and contrast. The two phones have the same face value of 720 by 1280 pixels, but Mijue M10 delivers more details of the same picture. Have a look at the left lower part of the landscape photo. On Cubot X6, you can only tell it was a lot of grass, while on the M10, you can almost distinguish one piece from another. And of course colors are more vivid on the Mijue handset.
As for webpages, apps, or anything with white background, Mijue M10’s display is colder with a little bit sepia, which I don’t like, while you can see pure white on the X6.
4. Camera
In the same light condition, Cubot X6’s back camera takes better photos than Mijue M10 with crispier details and livelier colors, while their front cameras were quite the contrary.
5. Operating system.
The Android 4.2.2 pre-installed on Mijue M10 is the original version with everything essential such as the Play Store.
On the X6, the OS differs a little bit from the pure Android 4.2.2. Every apps icon has a background, which is lovely and helps make the interface more compact. Besides, the apps and widget sections are separate, so you don’t slide across them.
6. Performance
There is something weird about the results on benchmark apps, but I will mention it later in case it affects your judgment. First of all, have a look at the real performance of the two smartphones.
You may not observe from the video the subtle difference that I felt in reality, but switch of home screens and pictures was indeed a little smoother on Mijue M10. On the other hand, cars of NFS Most Wanted run in the same speed on both phones, sometimes a little bit faster on the X6.
From my 3-day experience, Mijue M10 and Cubot X6 belong to the same level in terms of smoothness, and they notched similar scores on GFX Bench. Though the Cubot handset is nearly 6,000 behind the M10 on Aututu, I still believe in my feelings.
The most weird is that both Antutu and GFX say the powerhouse of Mijue M10 is MT6592 which has 6 cores. I tried two sets of the model, and the results were not different. MT6592 with 6 cores! We all know MT6592 is an 8-core CPU, which is proved true on any other mobile phone. I personally can’t explain the absurdity.
7. Battery
Battery is most people’s top concern but I couldn’t give exact time of duration in my previous reviews. This time I let a 720P music video loop on the X6 and M10 when they are watched over by the Battery Monitor Widget. With the same 2,200mAh capacity, Mijue M10 and Cubot X6 lasted 4.5 and 5 hours respectively. I hope the numbers help you anticipate their durations in normal use.
Conclusion:
Anyway, Mijue M10 is the cheapest 8-core mobile phone presently, where no major drawbacks have been found during my short trial. Regardless of how they will perform in the long run, I personally think the M10 is better worth its price than Cubot X6, or any other Octa-core stuff.
History tells us that USD150 is the ultimate mainstream price for Chinese-branded smartphones with mainstream components, so we can expect quite a number of 8-core 720p-display 1GB-RAM phones with worse-than-mediocre cameras to emerge around the price before the release of the next generation of the MTK chipsets.

Full Review: THL T11, really fast with 2GB RAM to liberate MTK6892 8-Core CPU

The good: 2GB RAM perfectly unleashes the potential of MT6592, so in terms of gaming, THL T11 is the one of the fastest 8-core smartphone I’ve ever experienced (the other is Huawei Honor 3X). Good craftsmanship as on previous THL handsets. The protective case is smart with automatic wake-up and can be used as a stand.
The bad: The protective case frequently flip open itself. The camera is disappointing.
Bottom line: Though it is 20 US dollars above the que-limit price for a Chinese phone, THL T11 is still worth the price, because it is very close to a high-end stuff in many aspects.
Price has long been my first concern if it comes to talking about a Chinese cell phone, so I didn’t mean to do much about the USD220 THL T11 when the cheapest phone with the Octa-core MTK6592 CPU has been 70 US dollars cheaper, namely, Mijue M10.
Fortunately the 2GB RAM drew my attention and made me wonder if it would help make a difference. Well, it did, and I saw something that stunned me quite a lot, like what you would see in the video below.
Yep, the cars of NFS Most Wanted flied! That gave me confidence to try Real Racing 3, which, seems not bad on the T11, too. And such a phone – I can call it a beast – of course deserves a full review. So here it is.
1. Design:
THL T11 is generally a copy of Xiaomi M3, or you may say both the 2 Chinese-brand phones stole the design language of Nokia Lumia 920, including a long rectangle face with sharp corners, curved-out left and right edges, as well as flat top and bottom.
As the T11 has a user-replaceable battery, there are inevitably seams on its edges for opening of the back cover. That aside, the handset inherits the good craftsmanship from its THL predecessors.
The rear side of THL T11 delivers a soft feel like that from a velvet blanket -- quite different from stock hard plastics covers; being a little bit narrower but thicker, the smartphone looks more compact than Xiaomi Mi3; and it has a neat appearance with no redundant buttons or holes besides a volume rocker, a power starter, a micro USB port, and a 3.5mm jack.
A bonus point could be the protective case which is composed of an extra back cover and a foldable piece of leather. You can flip the front cover open and close to wake up the display and let it sleep. And like the Smart Case of iPad, the T11 case can be used as a stand for video watching, too.
Perhaps the condition is just for the very T11 I hold in hand -- the front cover open itself due to a tensile force, so I have to let the face of the handset down when I put it on a table.
2. Display:
This week I tried three Chinese mobile phones with 5-inch 720p screens, namely, Cubot X6, Mijue M10, THL T11. Of them, Cubot X6 and THL T11 have the worst and best displays, respectively.
On the T11, you can see all the details of an image that should be shown with the resolution of 1280 by 720 pixels, and the mild and lively colors are quite eye pleasing.
3. Camera:
If THL T11 had a good camera, I would be willing to spend 30 US dollars more --- USD250 for a cellphone with no major drawback is quite a deal. Unfortunately, THL would rather save the money for a lower price.
The back camera is just a little bit better than a total disaster with low real resolution and pale colors, while the front camera is somewhat heartening. By the way, remember to peel off the piece of blue protective film on the lens of the rear camera, or you’ll get a more blurry picture.
Normal light:
Low light:
With flash:
Under fluorescent lamp:
Selfie:
4. OS:
The T11 runs on the pure Android 4.2.2 with Google Play store pre-installed. People on XDA-developers may not be android purists, but I think this hardware would set your mind at ease for development.
5. Performance
With the gaming experience aforementioned, I knew the T11 would have high scores on benchmark apps. And it did. Antutu gives the smartphone a high score of 27196 and GFX Bench 3.0 says it is able to deal with 41 pictures of 720p resolution in a second.
Not only gaming, every operation on the THL stuff is fast, such as switch across apps trays, open and close of apps, slide of pictures. However, I still feel hiccups during the switch between widget trays – the same problem with all Android 4.2.2 Chinese phones I’ve tested.
It seems that the MTK6592 Octa-core CPU and Mali450 MP4 quad-core GPU make a real fine chipset allocation, which, however, needs a big random access memory (RAM) to liberate itself from fetters. According to my memory, THL T11 should be as fast as Huawei Honor 3X, and the latter, worth more than USD300, happens to contain a 2GB RAM, too.
6. Battery:
Just like what I did on Cubot X6 and Mijue M10, I let a 720p music video loop on the T11 till the battery dies, and at the same time, the Battery Monitor Widget watched out the power consumption. Finally, the 2750mAh lasted the smartphone for about 6 hours of playback.
7. Others:
Though I don’t feel NFC is very useful, at least for now, this module on the T11 is quite responsive -- it connects very quickly to Nexus 4 and transfers files quite smoothly -- have a look at the video above.
8. Conclusion:
Of all cheap Chinese phones, THL T11 may be the first one that I think is a worthy opponent against some internationally known brands. Except camera, the T11 is fine by all means, and in terms of speed, it should’ve been one of the fastest of all 8-core phones by far.

Awesome review. Thanks for info. I am really interested now.

It's just one week experience, so it may or may not be as good after long-time use. You need to see some consumer reviews for more fair judgement.

Which website did you order your phone from? How long did it take to reach you?
Thanks

Hey, i didn't order it. I'm in China and get the phone from a friend who sell phones.

nice review man.
How about facebook? Does it crash? Some people said that fb version 7 runs ok.
Thank you.

Great review indeed. Especially the battery performance verification method. My T11 is on the way (should arrive within the next week).
People claim that the notification led only works when charging.. Is it true? Is there any way to fix it without installing another ROM?

Sorry i didn't notice such details, but i'll check when the handset is available again. About the battery performance verification, it was learned from a guy on XDA.

I think so. T11 is the best mediocre Chinese phone by far, in terms of craftsmanship, smoothness, display and comprehensive strength.

Hardware
OS: Android 4.2.2
CPU: Mediatek MTK6582 1.3Ghz Quad-core
GPU: Mali400
Memory: 1 GB RAM / 4 GB Storage
External Storage: MicroSD up to 64GB
Screen:4.3” (800×480) display - GorillaGlass2
Notification LED
Rear-facing Camera: 8MP with 1080p video at 30fps
Front-facing Camera: 2 MP
Wireless: Bluetooth 4.0, 802.11 a/b/g/n
Battery: 2200 mAh (removable)
Appearance and build quality:
The JIAYU G2F seems well built, feels solid in hand and looks really good, on the sides it's real metal frame painted in black (unlike in F1) that contribute to the premium appearance.
The dimensions are almost the same like at 4" JIAYU F1- but in G2F you get 4.3" OGS display .
On the top you got the Power button + 3.5mm headphone jack.
On left it's the volume rocker -doesn't feels loose.
On the button there is microUSB port+ Mic
The back of the device - you can see the regular Sim slot+ microSD slot (+comparison to JIAYU F1):
Actual device weight- 132.5g
Size comperrison VS JIAYU F1:
Call Quality and Speaker:
The call quality is Good even little bit better then JIAYU F1 , the speaker is loud enough with average quality.
Android "4.2.2"
JIAYU G2F comes with android JB 4.2.2, some chines apps were pre-installed that I have deleted them after gaining root access with Frameroot app :good:.
The Ui is nice, and it smooth and I hope JIAYU will release Android 4.4.2 KitKat fir this device.
I must menttion that this rom forces you to get SD-card since all the free ROM (2.3GB) from built-in 4GB is used for app partition- so you must get SD-Card if you like to use camera and etc'.
Display:
JIAYU G2F uses 4.3" 480P IPS OGS panel, the colors are vivid, great viewing angels and good brightness for outdoor use.
The touch screen is responsive and accurate- I have no complaint about the screen & digitizer quality .
Some user were unhappy that the resolution was downgraded to 480P from 720P on TD-SCDMA model, but for my opinion it is OK PPI for 4.3" display + the OGS panel looks better.
Camera:
The JIAYU G2F comes with 8MP OV8825 back camera sensor and 2MP front camera sensor:
Compering to its cheaper brother -the F1, this camera quality looks nice, for ~105$ device it performs really good.
Here are some Samples images from the back camera- Click for 100% size:
GPS:
I have tested the GPS over short trip- had no problems, the First fix can take up-to 30sec but afterwords the fix is fast and GPS performs OK.
Wi-Fi:
Wi-Fi reception is average - not the best I have seen - but I had no problems even in The most distant point in the house..
MTK 6582 Performance:
The MTK6582 Quad-Core got really popular , replacing the good old MTK6589/T and now we can find this Quad -Core in devices under 100$!
MTK6582 offers really good performance in very affordable price, now you can find this SOC in smartphones running Android 4.4.2 KitKat under 100$ with free shipping!.
For 480P/720P displays this SOC offers fluid experiences and lag free UI Transition Animation.

Battery:
The JIAYU G2F comes with 2200mAh battery, it looks that the capacity rating is legit- it weighs 43.3grams:
The interesting thing is that the G2F battery is identical to F1 battery and only the chemistry is different (3.8V for F1/3.7V for G2F).
The battery life is good, with such spec's it can last 2 days of normal use.
Conclusion
THe JIAYU G2F looks like really nice device, it has great design, solid build, great performance and really nice 4.3" OGS display ,
I just wish JIAYU used 720P OGS dispaly and it could be really great Smartphone.
My Score: 9/10 .

Thanks for the great review! I'm looking for new phone to replace my GSII and this could be interesting.
I'm having trouble finding the 4.4 Kitkat rom, is it officially available?

No, unfortunately there's nothing beyond JB now.

Perfect Review! Thanks. Now i know that the Xmas surprise for my wife works, she likes the size of her F1 but not the camera, and you said that g2f cam is better.

My wife has it now a few days. The Cam, the Display is better and it looks much more nice, not so thick. I rooted it. Yesterday the LED was from ghosthand shining and after the phone was freezing. Only put the Batterie out was the way to start it new. Today it freezes while writing whatsapp (Touchpal keyboard). If there are more hangouts i must flash the Stockrom or another Rom again i think...?

Great phone, but the freezing during charging is annoying, happens almost every night, in the morning the green led is on and the phone is dead until you take the battery out.
Wife is pretty pissed as she uses the phone as an alarm clock...
Checked with Jiayu, found several identical complaints on their store page, all of them followed by a note from Jiayu saying they will contact the person via Email with a new ROM that would fix it...
Wrote a comment, I'll update if I get the new ROM.

The freeze on charging issue is a problem of the 0.36 firmware version, that I also have.
I ask with many mail to jiayu the same firmware or upgrade that you talking about: in his FAQ it talking that send in mail some correction or that it have posted on his site (??? WERE ???) the firmaware.
If anyone know were, or have the firmware please send a link.
Meanwhile to solve the problem, the solution is very simple: once put in charge the phone performed a reboot. This will free the ram (I think it's all over them the problem: the RAM dont refresh) in the morning you will find the phone on and not freeze. To reboot I found convenient install reboot widget (i can't post url, search in play store) with a tap will reboot the device.

Jiayu G2F display problem.
Nice phone. But 4 months after the purchase and decent usage, the display starts to lose its brigthness.
Just two days ago, brigthness dramaticaly lowered, and now it is almost imposible to read it on the daylight.
The problem is caused by hardware, because I had tried many ways, reseting, changind the settings. I even bootloaded factory test menu in chinese, and there is no help with that at all.
What can I do ? Phone was bought in China, i doubt there is a waranty.

[REVIEW] Lenovo lenovo Vibe X2: octa-core, 4G, 5" HD, 2GB RAM, lightest metal phone

[REVIEW] Lenovo lenovo Vibe X2: octa-core, 4G, 5" HD, 2GB RAM, lightest metal phone
Last the September 2014, the Chinese giant Lenovo launched a new phone with 5.0 inch screen called Vibe X2, which became also the flagship smartphone on IFA exhibition of Berlin.
To have a better idea of the level, this phone was sharing stage with the almighty Samsung Galaxy Note 4, Sony Z3 and Huawei Mate7 ect
Are you maybe willing to know more about what can this Vibe X2 offer? Lets start with this review

Unboxing Video:
As seen the video, the package of Vibe X2 is very different and I would even say more creative than others. As we usually see, it presents a double level design, in the first one we have X2, slot needle, warranty card and user manual. In the second have USB cable, special attention to the 1500mA charger (normally they are just 1000mA) and earphone. We have already told before that now many smartphones do not bring earphones in box, something very inconvenient for the users, but Vibe X2 has it and it’s appreciated.
Appearance
After unboxing it, we will see the Vibe X2 is a very elegant terminal:
No matter if we have chosen the gold, red or white version, the front part is completely black, occupied mostly by the 5” screen.
Once turned, it's completely flat, I love it!
On the side body, Lenovo Vibe X2 uses a very unique four layer design, different than other smartphones that use to bring a more integrated design... With only one color.
Talking about the dimensions of X2, they are 140.2x68.6x7.27mm, very close to the 4.7 inch iPhone6 dimensions (138x66x6.9mm), with the difference of screen size on favor of the Lenovo model.
The thickness is also once of its strengths, specially because the camera does not protrude as we’ve seen on the iPhone6 or other phones.
Lenovo has used an aluminum and magnesium alloy for the structure, which is around 45% lighter than stainless steel. So the Vibe X2 only weights 120 grams, being 1 gram lighter than its predecessor Vibe X S960.
By the other side, power and volume buttons have a very nice non metal feeling when you touch.
Lenovo Vibe X2 has a dual SIM card slot in one tray on the left side, where we can put together a micro Sim, and a nano Sim. And what is more interesting, both slot support GSM/WCDMA/LTE networks.
Hardware

Front Camera 5.0 mega pixel, supports Skype Video Calls
Rear Camera 13.0 mega pixel / Auto Focus / Flash Light
OS Android 4.4 with Vibe UI 2.0
Battery Built-in Battery 2300mAh
It’s equipped with the MTK MT6595M Octa Core CPU from the well known Mediatek and 2 GB of RAM, running perfectly with a resolution of 1080p on the 5.0 inch LCD screen.
With this hardware, it scores as high as 45000 in Antutu tests, so no matter what normal use, video or game we play, it goes with speed and high quality image experience. Adhering to MTK always probes quality experience for media, so Vibe X2 can play 4K videos incredibly smoothly .
The rear camera with 13.0Mpx and front camera with 5.0Mpx bring high quality images in this smartphone.
One of the main point on this Vibe X2 is not only that the dual SIM slot support 4G LTE, but both can be active simultaneously (it means your calling party will never hear "Not reachable" message if he calls you on second mobile number when you are busy on talking on first number. He will be just on "waiting" that time ....), very useful!
About the storage it has two versions, so we can choose between 16GB and 32GB, what a pity is that it doesn’t support micro SD card extension.
Finally the 2300mAh battery makes delivers a good time of endurance.
Note: Official ROM only has Chinese and English languages. However some sellers like Etotalk (http://www.etotalk.com/lenovo-vibe-x2-x2cu_p6697.html) customize the ROM so it comes with many other languages and Google Play installed.
Screen
I have already mentioned about the 5.0 inch screen, capable of offering 1080p resolution with a pixel density that reaches 445ppi; in addition it uses LTPS technology, which means low power consumption.
Lenovo Vibe X2 screen support customized parameters like custom color and saturation ect.
As usual on almost every phone, it brings a “Smart bright mode”function, capable of auto detecting the level of light and enhance the visibility of the outdoor and indoor environments instantaneously.
Camera
As you can see on the samples below, the photo quality is excellent with the main camera thanks to the color reduction technology. Showing colors close to true even with very different light levels.
The camera app includes Quick Shot technology for still camera and video, improving the users shooting experience. Of course, these results rely on “Super Camera 4.1” Function developed from own Lenovo labs.
Note: When the phone is on sleep mode, we can activate the quick shot function by doing double click on the "home" button, very useful.
Battery
About time of endurance, because of the ultra-thin body of this phone, the battery is only built-in 2300mAh, facing the MT6595M CPU and 1080P screen, it is kind of stressful demand.
After running some tests:
 Watching 30 minutes online video, power dropped by 10%
 Playing Asphalt 8 game for 20 minutes, made the battery drop by 6%
 Standby time during the night (so 8 hours with Bluetooth and GPS disabled but keeping WIFI on) and the power only dropped 4%
 After one day of standard use, we still had 24% of battery
With this figures, one charge per day should normally be OK. We must also think that I was simulating normal use, so I didn’t enable“Ultimate Power Saver Mode”during the tests.
Other says that opening it, the phone should be fine for 2 days of use, even 3 days some say, although I consider it too optimistic.
Conclusions
From my side, no questions the main point of Lenovo Vibe X2 is its cools and elegant appearance, with that colorful layer design that breaks the common practice of smartphone side design.
The aluminum and magnesium alloy frame keeps the phone weight very tight, in a way that having the terminal on the hand feels very light, even lighter than iPhone5 despite the different size,
To be honest, we cannot look only to the design, I wouldn’t be practical at all for a smartphone review. The powerful hardware brings us speed, then, but also the quick shot function, dual full active SIM with 4G LTE support
And about places to buy it. I have already a wide experience dealing with Asian sellers, and sincerely have been cheated (not same product, low quality, long delay, orders canceled, excessive customs costs...) so lately I prefer to go to those ones giving me more confidence like Etotalk (which as I said also modify the ROM to include more languages) who in addition uses VIP DHL shipping, so normally it takes less than 5 days to have the goods on my home.

What about Lollipop for this phone?
