Will it be possible to combine both screens so that it appears like just ONE screen thus having a 7.8" screen?
And is it truly 2.1" notification bar screen?
Because the Nexus 6 has a 5.9" screen but the entire body is 159.26 x 82.98 x 10.06 mm
The LG G10 is 159.6 x 79.3 x 8.6mm
I find it VERY hard to believe that the LG's secondary screen is 2.1" Perhaps more like .21"? (notice my period placement)
The second screen only covers a part, not the whole with. It's about 200x1000 pixels or so... The two front cameras are left of it.

Each screen uses its own backlight, seems like a lot of work would be needed to combine their brightness levels for a uniform appearance. Also like ^ stated, the ticker shares that width with the cameras...

the 2.1" obviously is measured diagonal.
Let's revive this thread 4 years later
so I have noticed that twrp recovery combines both screens into one but of course it has a bad notification bar but if you need proof of this I can take a few pictures with another phone. But my interest is if twrp can do that with no code for that, can someone code and shape the notification bar and combine them in regular Android UI? ( I use a LG V10 with a nugat 7.0 version of andriod. )

I purchased the Photon on release day and have had no problems with it (shutoffs, reboots, screen of death, etc.). I came from an Iphone 4 on AT&T because I wanted unlimited data. My only gripe is what appears to be touchscreen sensitivity/preciseness.
When I look at my Photon with the screen turned off in the sunlight at an angle, I can see a grid of boxes that appears to be the touchsensing grid. When I look at an Iphone the same way, I can see a similar type of grid.
The difference in the grids is substantial, the Photon grid boxes are significantly larger than those on the Iphone.
I've noticed that in general, the Photon has worse touch sensitivity than the Iphone 4 did. Making exact screen presses on website links, for example, is simply not as fluid or precise. Not even the unlock keypad works as well.
I haven't had an opportunity to look at the Epic Touch (GS2), I'm wondering what the grid is like on this phone?
Anybody else here notice a lack of preciseness with the Photon touchscreen? Is it an Android issue or a hardware issue?
The grids are becuase the screen has an arrangement of pixels and subpixels called PenTile Matrix, which makes it appear as if it had more resolution than it actually does.
That does not affect, however, the touchscreen quality. The SGS2 does not have the square thingy.
You have too much time on your hands.

No, I am familiar with the pentile nature of the screen.
l am referring directly to the capacitive matrix grid above the lcd used to sense finger presses. The grid squares are very large in comparison to the iPhone. That makes me wonder if the touchscreen is less accurate. Look at both phones with the screen at an angle in direct sunlight. Each has a grid.
I would definitely agree its not at fluid as other phones I've used but damn can it be touchy. Scrolling down a webpage always seems to end up in a unintended click for me.
Yeah mine can be touchy as well. Mostly with the xda app

My girlfriends' SII recently got her screen burned in,which got me thinking "can this happen to me?" Is it even a problem for us EVO users? I know the screen for the SII wasn't an LCD screen , and I believe the EVO's is. Any answers will be appreciated!
LCD do not burn in, which is what the EVO LTE has.
IPS LCD screens can have what is called image retention or image persistence, which looks like burn in, but it is temporary and goes away if you stop using your device for awhile or flash a bunch of colors quickly on the screen for awhile. http://en.wikipedia.org/wiki/Image_persistence
Amoled screens can have burn in, which is what your girlfriend has. This is why I cannot understand why people want onscreen buttons on phones like the galaxy nexus. I would guess a majority of Galaxy Nexus phones will have their navigation buttons permanently displayed(it is really faint usually) on their phones within a year and it can probably be seen during any full screen activity in which a gray or similar light colored background is shown.
I am not sure if the Super LCD2 used in the EVO LTE is an IPS screen or not(I think it is based on a quick google search and the fact that the colors and blacks look amazing) so I can't tell you for sure if it will have image retention issues, which again, are not permanent anyway.
Thanks! That's exactly what I thought, I just wanted a second opinion. Thanks for clarifying the difference between image retention and screen burn in. I'm fine with it as long as its not permanent.
If you find the image retention lasting a long time, you can run something like this: https://play.google.com/store/apps/details?id=net.ujacha.deadpixel&hl=en
It's meant to detect dead pixels, but by cycling through all the colors, it "erases" the image retention.
Ideally, you can find a video on youtube (there are plenty), just search for monitor calibration or hdtv calibration and then play that video for 5-20 min. (The video should just be rotating full screens of colors like the dead pixel finder)
Hey quick Q, i bought a S3 on Wednesday, just noticed that when the screen is green ( or when browsing 0 brightness) that there is a faint whitish pixel that always shows up. Its not visible on black screens, red, purple, or blue.
Anything i can do? Or should i not even bother as its only 1 and how often does the screen go green.
There is no such thing as stuck pixels on AMOLED screens, only defective (either always-on or always-off) pixels or lazy pixels.
While it may sound stupid when related to what I just said, try the app 'Dead Pixel Detect and Fix' and let it run for half an hour.
It will cycle the colors very fast. It will most probably not work but it's worth a try.
If it still appears, try taking it back. Defective screens on a new 600$-handset is not very nice.
ah i see, but can you explain to me why it does not show up on a black screen/background? I just find it interesting and would like to know the reason behind it.

If it bothers you, just take it back to where you got it from and get it either fixed or see if they can give you a new one.
LCD screens use a white backlight illuminating the whole screen from behind. White includes all visible colors from near-infrared to near-ultraviolet.
To create the different colors they use crystals which are rotated by a power source in the correct angle that only a certain color (e.g. blue) is visible.
LED-Screens [*] and their derivates such as OLED get rid of the backlight and instead of using crystalls, replace each dot with a ligh-emitting diod (LED) which by itself gives light. However LED's have a big deficit; they can only produce one single exact color. So, similar as with the old CRT screens, LED's use multiple colors per pixel [**], these are the RGB colors (Red Green Blue). So each pixel is made up of multiple so-called sub-pixels.
If all 3 are lighted, they mix together to white, any combination in intensity (from 'off' to 'full brightness') gives you millions and millions of colors to display.
(It's easiest to see on large-scale LED televisions, just move very close and you see the 3 tiny 'lamps')
Now your particular issue is that a certain, due to one of several possible issues is not powered off or connected incorrectly; it is lightened at the wrong time.
So the reason it only shows at certain combinations is, that at other combinations you cannot see it due to the difference in color being too marginal or the other LED's also being off.
While it's unnerving, these issues keep arising during production. One has to keep in mind that one such small screen is made up out of thousands of individual light sources which can each be triggered individually to form millions of different colors.
Usually quality-control should get rid of such screens, but sometimes one slips through. I'm not sure what Samsung's standard for the S3 in regard to maximum defective pixels per inch or unit is, but you can (and should) always try to get it replaced.
[*] A lot of cheapskates sell LED televisions where in fact a normal LCD panel is built-in but they refer to the backlight source which in their case (and most other current productions) in fact is an LED source. It has nothing but the name in common.
[**]
This is not entirely true since structures such as active-matrix OLED (AMOLED) share LED's between pixels to cram a higher pixel densitiy in the same physical size.

Hello,
I recently picked up a LG G2 to replace my galaxy note 2, after having the phone for 4 days I thought I would deliver my review.
I always find it helpful to read reviews from actual owners of the phone rather than just the standard review sites. This review does not contain exact specifics but instead my view of the phone rather than an experts. I hope you find it useful if you are looking to purchase the handset or looking for some owner opinions.
Bit of background on previous phones:
HTC Hero
HTC Desire HD
iPhone 4
HTC Sensation
Nokia Lumia 800
LG Optimus 3D
Samsung Galaxy Nexus
Samsung Galaxy Note 2
Look,feel and build quality:
After opening the box (very difficult as mine came with the free official LG case) I was pleasantly pleased with the overall look and feel of the phone. Coming from a galaxy note 2 I was used to the whole plastic feel of the phone, granted a nice metal or glass finish would have been good but overall it is a very appealing phone.
Switching on the handset for the first time illuminates the entire front of the phone, at this point you realize how attractive the phone looks with the cut back bezel allowing everyone's attention to be placed on the fantastic screen (more on that later).
Move to the sides there is a simple metal band which circumferences the entire phone, adding a little detail to the otherwise plane sides.
To the back; we have the standard environment stickers a nice metal engraved LG badge and of course the unusual buttons. The camera, buttons and LG badges are all in a direct line in the middle of the handset which I feel visually appealing rater than the current trend of placing the camera in the corner of the handset.
Onto the buttons, an usual twist on a otherwise standard placement I find that it is easy after a couple of days to become used to the unusual placement. As your finger will usually always land in this area it allows for easy change of volume, quick key (camera / note) and the unlock button. I also find that the unlock button lighting up when you unlock the phone (nice white lines around it) is a nice touch.
Other details on the front include a nice LG badge embedded in the screen, front camera, speaker (standard silver finish) and a LED notification on the right hand side corner.
Overall I find this a nice middle ground between something such as an iPhone or HTC one and a Samsung device, due to it being sealed it appears more sturdy and has a better construction than the galaxy line but due to the lackluster plastic cannot live up to the standard set by apple or HTC.
Hardware:
On paper this handset stands atop the very large android market, in real life it does not disappoint. Use of the phone is a joy due to the snapdragon 800, there is 0 lagg using launchers (tried apex/nova/stock), multitasking and using slide aside happens instantly and web pages load almost instantly.
The screen needs to be seen to be believed, watching videos (especially the stock HD videos by LG) really shows off the screen. With almost 0 bezel around it shows the true beauty of the screen. Giving a little more saturation than a standard IPS, not to the length of a SAMOLED but maintaining white whites and black blacks. Colors pop, look extraordinarily accurate and pictures and moves look stunning on the full HD 5.2" display.
Battery life is excellent thanks to the 3000amp battery, allowing for twitter facebook full google intergration as well as wifi/gps/data enabled will easily power through a day with 4 hours of on screen time with brightness set to 100%.
Camera quality, yet to be fully tested by myself but some of the shots taken have been excellent. Outdoor in well lit conditions produce excellent clear results with a brilliant amount of detail captured. Night time / low light photo seems on par with other high end smartphones, thus far I have had some mixed results as with my previous handsets. I find OIS seems to work very well, taking photos in a moving car led to no blurred photos.
Software:
LG's software I find "borrows" many features from Samsung, such a smart stay / pause many of the camera features and over-all camera UI. However this being said it does have less unnecessary bells and whistles s4/note2&3 come with. The LG does come with a large variety of features, TV remote, gestures, Qslide and knock off. Double tapping the screen to lock/unlock is easily LG's best feature implemented, this counters any downsides of the rear mounted button i.e when using in a car holder. Many comments have been made on the task bar I personally do not use the Qslide option lists however the volume control (again helpful due to button position) as well as quick toggles are many but not overwhelming. Within a few hours I was used to the over-all layout and could quickly toggles and utilize these features.
One issue I do find is that you are able to customize the on screen button layout, helpful if you are left handed or prefer you button in a different order. Despite this you are unable to set a multitask specific key e.g. nexus line. Instead long holding the home button to activate the recent app list.
Over-all:
My overall week impressions of this handset are excellent, ergonomically speaking the size of the phone is perfect. People do not complain about screen size but handset size. By removing the bezel and fitting a 5.2" screen in what is a 5" screen body is a fantastic move by LG. The button placement takes some getting used to but software implementations manage to cure any issues you can have with this (knock on/off when the phone is laid down and volume adjust in the task bar i.e in a car dock). The hardware of the phone comes to impress and does, camera processor screen and battery are all market leading. Software is busy, however brings some very useful additions to android, improved if not a little OTT task bar, gestures and qslide give some good flexibility.
It has been agressivley priced at 400 GBP from three mobile sim free including free official LG case puts it in the same leagure as a preowned HTC one or s4.
From my perspective this is the perfect phone, smaller than the note 2 and bigger than a s4 without the foot print.
Good:
Screen, processor, and overall speed.
Battery.
UI implementations
Camera
Excellent ear phones included in the box

Hey guys. Have been doing some LCD comparisons for my droid mini and thought hey why not investigate this phone as well.
My quick story:
1st g2's screen for water damaged and I got a replacement. The picture was perfect with nice color balance..not too cold or hot.
2nd g2's screen was way too warm in color not to mention the phone would get hot...I returned it.
3rd g2's screen was still warm but not as bad as the 2nd. The screen stopped responding to touch randomly. The phone Was replaced under warranty.
Which brings me to my current phone. This screen is different.
Nice color balance like my first one but I notice its a little over contrast/grainy where u can see the difference if you hold them side by side with Another G2.
Also noticed the screen flickers around 45% or so which my previous phones did not do.
Don't feel like going through exchange process again just for this.
Have you guys noticed a difference in the LCDS for this phone?
Is there anyway for you to know what kind you have without taking the phone apart?
Yeah there are two panels, LGD and JDI. There's a neat tool that requires root which shows you which panel you have. Aside from color differences, kernels have different configurations for the panels so if you flash a LGD kernel on a JDI phone you'll get white lines. Most kernels, however, automatically detect your panel and installs a patch.

Why do we have two panels? And which one is better?
Sent from my LG-D802 using xda premium
I don't know, my best bet would be that the demand for the G2 was greater than what LG originally thought it would be and had to ask JDI to make them panels to catch up with the demand. Or JDI could simply offer them a couple panels at a really attractive pricing, and LG chose to accept that.
As for which panel is the best - I don't know of any tests have been made to compare the displays in terms of color accuracy and gamma, brightness and so on. But generally, LGD panels make less of a mess when flashing
