Now that Android can be installed from NAND, I had assumed that the problem with the screen only displaying 65k colors would be fixed. It still isn't, is there a known way to fix it or any progress being made to fix it? At the very least, is it known what the issue is? I thought it was a problem with WM utilizing only 65k of the screen and that carried over to android when it was run over WM, but now that WM is eliminated that's obviously not it. Anyone know?

There was a discussion about this back in 2010: http://forum.xda-developers.com/showthread.php?t=807307
Some say its 262K. Others 265K or 16M. It's all very vague.
According to Microsoft its 262k

I hope someone sheds some light on this, gradients look awful on my screen.

Seriously, it's the only thing holding me back from using this phone full-time. You can see a great example of it in the widgets.
I agree, widgets look terrible, specifically news and weather widgets (genie.apk), power control, etc (anything with the black gradient background).
However, they only look bad on some launchers (on launcher pro, for example, with high quality scrolling turned on, widgets look exactly how they are meant to look - somehow launcher pro manages to 'smooth' the gradient).
I think this should be made a priority as the banding is very visible in many apps, and especially when watching videos on the device. It is very noticeable in the new gingerbread ROMs, which make use of more subtle gradients (take the notifications bar, the phone application for example) - fixing this issue would bring android on the HD2 up to a whole new level!
I'm going to do some digging and see what I can find...
i dont think we can improve the screen to much higher than what is meant to be.if you have a normal plasma tv.you cant watch 3d movies from it,because it was not intended for 3d.same thing with the hd2 screen.

But isnt that always MS's way of looking at things, being conservative opposed to using the capabilities? MS has never used anything to its fullest capacity, they are always on the reserved side so to them less means better compatibility and less issues. I wouldnt go based on MS's articles or opinions, I think the best to answer the screen capability would be HTC - the maker.
But thats just my opinion.
For me, some sense builds look more colorful than others do.
is it possible that these builds make use of the displays capability?
Cause when I use Froyo everything seems to be paler and less colorful.
And its not just the wallpaper..
This is a concern of mine aswell, I hope it really is not a hardware limitation

I thought that limitation was just because that's all WM6.5 could handle. I'd be surprised if the screen couldn't handle 16.7million colours. It's just a standard TFT device after all.
Perhaps it comes down to drivers?

Earlier today I got into a discussion about CRT monitors with a bunch of nerds. We all spoke lovingly of the ffffffTWWAANGGGGGGG noise that degaussing makes and the general benefits of doing this action periodically to your screens. One of the gentlemen in the room mentioned that his Motorola Droid Evo 4g has a screen flicker and washout much like a crt that needs a degaussing.
This led me to wonder, "Why hasn't the dev community created a degaussing application for our phones?" After all, we spend dozens to hundreds of hours and dollars in modification to and accessorizing our phones. Why not take it a step further and make sure that the screen itself has an even longer life?
So who is with me dev scene? I'm to damn stupid to develop this application as my fundamental knowledge of how linux actually works on a ground level is severely lacking. I implore one of you randy fancypants out there: Please help nerds have that delicious fffffTWANNGGGG again.
Edit: I just realized this would be much better suited for general android application development. Can a mod move it?
hey matey, this would be a great idea, however lcd's dont need deguassing lol
althought it would be amazing as a screen on animation or a timeout animation lol
i can see why you want a degaussing feature but i dont really think its necessary and that's wiithout taking into account its impossible lol.
degaussing is he method of clearing magnetic interferance and other electrostatic interferences out of the screen that just dont effect a lcd screen which is one of the benifits of them
great idea though!!
Okay well that being said I think it would be a fantastic boot animation/noise.
of course ! that would be amazing, using it as animation and boot animation would be cool... have you seen the CRT animation for screen off and on, its on cyanogen mod roms its pretty neat!

SGS4g actually needs degaussing- mine at least
I tricked a nephew of mine to trade an old samsung S4g vibrant (tmobile) with a relatively new Galaxy Y. I wanted to play around with an older phone for tweaking experiments and I noticed after a month now (and 5 Roms and several wipes) that a shadow of the android keyboard shows up everytime the screen displays a white background. It does not show up on black though and it reminds me of the old degauss issue with crt monitors.... Is there any solution for this?

This sounds exactly like LCD burn-in. I don't think there's much you can do about it if the screen already shows ghost images like that.
A fake degauss would be a great animation for a FC, but since something is already crashing, wouldn't the animation have trouble playing smoothly, especially full-screen?
(Apologies for the junk post, but I'm trying to get enough posts to give feedback on stuff in the Dev section.)
Hello,
I picked up my GS4 about a week ago but haven't really used it in direct sunlight until today. I was outside, and the sun was shining brightly on the screen. Home screen was fine, and darker images were ok, but if I were to go to an app with a primarily white background, or open up something which used the keyboard (texting) the screen would flicker pretty noticeably. Brightness is all the way up, and auto tone was off.
Has anyone else seen this?
yup this is normal esp when using the keyboard.
Im not sure if it will be fixed.

I guess my question is, is this a hardware issue with many GS4's or a minority. I came across a thread on the Tmobile GS4 forum where people were experiencing it, but it seems not everyone is.

Its a hardware thing, but also its only in touchwiz so a developer might be able to turn it off so to speak.
It adjusts the color and tone no matter what to save the display from overheating and or burning in...
Does it a lot and I notice it cause im weird about those kinds of things.
If you use CM 10.1 or AOKP its gone.
ive made some progress with the RGB light meter on this; hoping a friend can write up some code so we can test out a 'smoothed out' transition and sampling rate and one that is sped up, averaged faster, but will take up more CPU and RAM and battery but more accurate.
here is another thread regarding it:
http://forum.xda-developers.com/showthread.php?t=2280715
http://forum.xda-developers.com/showthread.php?t=2284726
Maybe if someone who is using CM10 or AOKP could test it to see if it is a software issues and not a hardware issue?
edit: slade and jet replied while I was writing this...thanks for the info. looks like it is touchwiz related.
edit2: just went out in the sun again to test a lot of different options in the display settings (which none worked) but is seems it is only happening when the keyboard is enabled. I am using swiftkey.
yeah TW and that sensor communicate; i believe the sensor itself probably works better ALONE, but TW changes it and throttles it for either battery or screen safety.
It is always dependent on what is being pulled up on the screen, though it can be mitigated quite a bit if you disable all power saving and screen auto features, and leave brightness under 80% or so.
yea anything under 80% in direct sun is basically black. all power saving and screen auto modes were disabled. i covered up all of the sensors too and it still flickered....

Not just a sensor thing per-say.
It's hard to explain, they most likely did it because they didn't want the amoled to burn in.
Its the same reason why the brightness goes up another 34% or so on auto above the max brightness. Only uses it when needed to save the screen and battery.
Does it on youtube too btw, bring up a video on wide screen then tap it and you'll see the drastic color shift
I noticed this thing when I got my phone also. I thought I was just imagining it but I guess it's an actual problem

Hey guys, I have to ask:
- Does this device have a bootloader lock such as sony smartphones when purchased from a carrier?
- Is there any sudden death/current bugs/defects I should look out for? (tinted screen, broken hardware buttons, bad touch controls, anything?)
- I see there's unofficial cyanogenmod support, is there anything not working? (gps, camera, nfc? threads don't seem to mention anything broken, is it omitted or there isn't anything to fix?)
- Anything I should do other than read the stickies? Samsung phones have a very important and easily corrupted EFS folder, so I'm on the lookout for anything like this on my next purchase.
Any answers will be greatly appreciated.

If you use autorec it will flash the JB boot loader, and a custom recovery (TWRP) so you can flash ROMs and what not. The only thing I've heard about hardware defects are lines on the screen. Vertical, horizontal and screen spasms altogether. When it comes to cyanogen, I've never used it on this phone. Unless you're one of those must-have-aosp sorta guys, stock ROMs are the way to go. On the other hand, I did use Mahdi for awhile and it was awesome.

It has a locked bootloader, yes.
- Is there any sudden death/current bugs/defects I should look out for? (tinted screen, broken hardware buttons, bad touch controls, anything?)
Yes there is. Check the screen. On some phones, the digitizer randomly stops working. Often occurs after a drop.
Check for something like this or something like this.
- I see there's unofficial cyanogenmod support, is there anything not working? (gps, camera, nfc? threads don't seem to mention anything broken, is it omitted or there isn't anything to fix?)
I wouldn''t say "Not working" as much as I'd say not working properly. Camera performance on AOSP is generally horrible and more often than not, a Stock based rom would be the way to go =)
- Anything I should do other than read the stickies? Samsung phones have a very important and easily corrupted EFS folder, so I'm on the lookout for anything like this on my next purchase.
The G2 also has an important EFS partition. It's not as easily corrupted, but make sure you have a backup of it at least.
Don't drop the phone, the digitzer is glued to the LCD - if the screen cracks, your digitizer dies.

Is it possible to unlock the bootloader?
I'm a sucker for AOSP, do you mean the camera has worse quality (as the stock has more options), or does it randomly stop working? Coming from an i9300 I thought this device would have all the necessary sources available for development, or is LG a bad company towards developers?
Also, is anyone compiling AOSP roms with linaro for this phone?

I'll advise you to go for a Nexus 5, One Plus One or wait for something with tons of development for AOSP ROMs like the two I mentioned.
Also there is a risk of permanent black lines that happens to some G2 owners, its suspected that heat is the cause but if it happens to you while flashing you'll have to RMA the phone.
There is a workaround for the locked bootloader. The camera quality is worse on AOSP cause the drivers for the camera are closed source. Development on AOSP ROMs is slow. Best option is stick to stock or stock based ROMs

i just wanted to add :
- how is the over all experience comparing it with samsung - htc devices , i have been using both of them for a while ( i dont like build material in samsung and update process with htc - i read that lg is making progress in this direction ).
- how does it feel after a while like the size,shape, build quality including overall performance .
im very close to buy one but im afraid a little bit - never owned an lg smartphone.

I came from a generation of small devices since before the sgs3(biggest device I had prior to the g2) I had a lot small devices so getting used to a bigger device was little but difficult but rather quickly and the button placement/knock on and knock code is a great feature and before you know it you will be knocking on all your devices(I spent about a month like that)
build quality is okay for a plastic device it feels nice but it definitely needs a cover to maintain it safe
performance is great, I never experienced any lag; camera took some great pics(in the day because low light performance is bad) and after rooting and installing the modded camera you will enjoy all the improvements in day/low light scenarios; and I use the phone for lots of gaming specifically emulators, so I was able to average about 20 hours a day with heavy ppsspp usage so both performance and battery life are killer

Hello guys, I'm new on Mi 9t, I have it since one month now.
I'm running 11.0.5 global (waiting for miui 12) and everything is working smootly (a part some heating problems and battery drain).
Yesterday I noticed a BIG strange spot on the right side of the display only when I have a black/dark theme (for example on Telegram) and when brightness/light around the phone is low.
I tried to googled it but I didn't find anything useful and still don't understand if it's software or hardware. I just get that is a common issue of AMOLED screen but in 2020 I don't get how this is not fixable lol.
Any suggest?
Thanks in the advance and I wish you a happy day!
Nope, every AMOLED is like that. Tested even on the S10 plus. No worries
