Android screen inversion problem

I was wondering if anyone else has experienced a problem with android on the hd2 where very occasionally on waking the screen up the colours become inverted? I couldn't find anything on the forums about it and it doesn't go away unless u reboot. U can still use the phone completely fine, it just makes things difficult to read.
I don't remember having the same problem in winmo which makes me think it's linked to android as I've only been running it on my handset for about a month.
I am using the cyanogen 6 android froyo rom with chucky's Droid rom for win and radio v2.10 (just in case that makes a difference!)
Next time it happens I'll try to get a screenshot too!
Any help/ideas on how to fix it would be much appreciated!

I also had that problem before, happened to me about 3 times with shu8i's previous build. But when you take a screenshot of, the screen shot is fine. CM6 related I guess but dont have clue. I just reboot

Same as above, couple of times on shui8, not a real pain, just rebooted.

Occured to me once on a sense build on Energy WM ROM.
Had to reboot to fix it

hmm guess its not necessarily android related then, and if the screenshot's coming out fine could even be the hardware! just seems to be happening to mine more recently, however since putting this post up it hasn't happened (of course!)
Cheers for the help guys, like you said its just an annoyance more than anything, just hope it doesnt get worse

I've had it once in FroyoStone V1, rebooted and then everything was fine.

inverted screen
hi guys, i've also experienced this problem, I was running at the Feather HD rev.3 at the time (great build BTW), and had this problem two times. As far as I am concerned I used my phone as usually ,so there is no root of this problem I am aware of. Obviously it is not even build related. I also attach screenshot.

I got the same inversion 4 times now with FroYo 4.6.
1/2 year with WiMo I didn't got it.
First I thought this occurs when unplug the power cord
but 1 hours ago I got an inversion just going from standby
to work.

This happened to me only once, while using sense ui, locking the screen and waking it. Rafdroid Desire HD Rom - MDJ Kernel
Can someone merge the thread with this one? http://forum.xda-developers.com/showthread.php?p=11161353#post11161353

same inversion
Hi, I have the same problem till reflashing to android, now I have MIUI and it happens approx. every 2nd day od use. Do somebody have any advice to this yet? Maybe it's related to version of RadioROM...?

Touch Screen Freezes?

I'm still getting touch screen freezes with any of the Cyanogen Mod Froyo builds, Bangsters/HyperDroid, assumed to be associated with the g-sensor.
I re-formatted my SD-Card and re-installed and I'm still getting freezes.
This is the 1 thing that is stopping both from becoming a perfect build, as everything else is amazing.
Any suggestions? Does it have something to do with AXI/NOAXI/EVO kernels? Under-overvolting? Is it the kernel?

Ive had problems with screen freezes with almost every rom, but i got barely any on this one. http://forum.xda-developers.com/showthread.php?t=790374
It also is a very good looking rom.

Yeah, I've experienced similar results, though I dislike SENSE based builds and prefer a Cyanogen Mod. I know Sense builds are more stable in the sense that they don't have as many touch-screen freezes, but would like to find a solution for the other builds.

I didnt get any touch freezes with this setup: http://leoandroid.com/viewtopic.php?f=212&t=168

Are the devs trying to fix this problem/Are they aware of it? I'm asking because I have not heard anything about this issue since months and the release notes list g-sensor as "working" (freezes are definitely related to or caused by g-sensor). The freezing problem still exists. I can even reproduce it perfectly when g-sensor is activated. Compass is shaky too.
I've tried a LOT of builds since September, mostly Mdeejays (love them ) the last few weeks. Could reproduce it with any build. Also tried many radio ROMs, many WinMo ROMs -> no change.

It's the kernel. Try one of the builds that use a current kernel (such as Hastarin's, rather than the old desire-based kernal on most of the stock builds). They still get the occasional, very short, freeze, but it is almost un-noticable. I'm using Darkstone's stock build (from here) with hastarin's 7.8 and it's fine with screen rotation left on.
The freezes are caused by saturating the i2c bus on the device. G-sensor is one of the things on that bus, but not the only one. The current kernels have increased the speed of the bus to help keep it clear, but it is now set to its maximum speed. I'm not sure if there where other fixes done as well.

I was using different versions of hastarins kernels. I don't get the freezes (only sometimes) when I hold the device in a normal way. But I get them EVERY time when the camera is facing down (for example when I look on the ground in streetview in Google maps with activated compass function, or when I play teeter). It's the same position you have to lay down the device for calibrating the g-sensor. The air bubbles will freeze almost every time in this position. All other orientations work very well.
I've made some videos where you can see the problem (sorry for the quality):

There is workaround which works: http://forum.xda-developers.com/showthread.php?t=803242... new hastarin and mdeejay kernels include this patch... and no, freezes aren't caused by saturating i2c bus but by occasionally not releasing i2c bus by g-sensor chip after reading its state...

My HD2 screen gets inversed color after a while.

IF somebody know the inverse option on photoshop when black comes as white and same for all colors it happens to my hd2 after a while when I unlock is cuz I press harder on it or is a soft problem?

I've seen a few people reporting this, luckily haven't experienced it myself. Nobody seems to have figured the cause as yet, but a reboot solves the issue (until the next time of course).

I had inverted colours recently. Was weird... I was on the phone when it dialed another number (possibly i did it with my cheek cos i'd been switching back and forth from keypad and loudspeaker settings). When i hung up my phone went strange with the 'inverted' look.
I'd love to know why because it's the only stability issue I have now.
Regards

This happened to me as well. I had to give it a restart. It happened after I waked the phone from screen off. It would be nice to find a fix for this.

Hope it is just a soft prob and not a sign of hardware fail.

Haven't tried it myself, but they say taking a screenshot creates a normal looking one.
So I'm afraid it is a sign of hardware fail. The bad thing is my phone is barely 2-3 months old.
edi: could you all please post the kernel you have. From what I've read, it seems an MDJ kernel problem. I used MDJ 0.2oc

I had this a few times before Xmas on one of Darkstones SD builds, only did it 4 or 5 times though. Taking a screenshot didn't work, just got a normal screen.
Since using NAND builds I've not come across this problem once, so I'm guessing the problem is Software/Kernel related rather than Hardware, which should come as a relief.

Did anyone find a fix for this?
I am using prj Clean Desire v0.3.2 (NAND) [Kernel: prj v0.4] and am getting the same issue, unlock the phone and everything is inverted but taking a screenshot with drocap2 comes out perfectly normal. It is happening every few days now.
I am going to try a different ROM and see if it still occurs.

Never had inverted colors in WinMo, with first Android SD releases I've had that problem quite often. But since flashed NAND Android 45 days ago haven't seen any inverted colors yet.

Had this problem today for the first time while in a call. A reboot put it back to normal...
Any known reason?

hyperdroid 2.1.0
I get this error occasionly on hyperdroid 2.1.0 but it happened to me again today.... its also happened on miui. No one found a solution or cause?

I have had this on various occasions and there i various topics on it but with no resolution of any answer as to possible cause.

[Q] Android NAND - occasional pale screen

Hey,
I've got the HD2 running extremely smoothly with the NexusHD2-Gingerbread v2.2 build.
Since moving to android and trying out WP7 I have been experiencing an issue where after a whole day of running perfectly I will turn the screen on to find everything is washed in white - it's like the screen turns greyscale but in white so everything is still visible and works but in white.
i don't seem to be able to find this problem anywhere else but it has happened with all the android nand roms and the WP7 rom - a soft reset fixes the issue. I'm currently using radio Radio_Leo_2.15.50.14 and have switched around but haven't found one that fixes the problem...
Any thoughts on what could be causing the problem??
Thanks, Luke.

I have the same problem sometimes. Will be glad if someone can explain!

Ive also experienced this, disappears after reboot or sometimes if i turn the screen on-off a couple of times, kinda weird.

Glad to see others are having this problem - seems to be so rare but I cannot find a solution. Would be interested to see if it still occurs now with standard wm6.5.
Anyone else experiencing this or have some idea of a fix?

i too have this problem.many times screen just go off like greyscale.can anyone help?

One more with the same problem...

Never had it with my currentrom (Hyperdroid) until I've read this thread.
Bump for wisdom.

Are you morons really that stupid
Get the screen out of the sun and away from hot surfaces you dumb bastards and it wont happen, it isn't a nand but a screen issue.
With stupidity like that you will be admins of XDA in no time

Erm what the f*ck? No need for that. Any actually, it's not a screen issue, it's an issue in earlier ROM's (well from what I've experienced). Like flash Cotulla's Desire ROM and it happens a lot. I presume you don't really like XDA due to your username? Banned maybe? Why would you even bother making a new account and just trollin'? That's sad, lol.
I only had it when the first batch of ROM's came out. Never withing the past month and a half.
It's like the screen goes negative.
But yeah, there isn't a clear fix for it AFAIK, you should back-up everything on your ROM and try an up-to-date ROM and see if it's still happening. I doubt it.

having the same problem as well
usually happens after i wake up, so during its idle time which is kinda strange
i also noticed it started happening after i installed cracked widget locker, any of you using that?

It happenes to my phone quite regulary but only running android roms, i think around september 2010 it happened the first time. I suspeced my phone, but even after getting a new hd2 it happens sometimes. It usually just happens randomly, not after specific actions. Sometimes it stays only for some minutes and sometimes it can be only fixed with a reboot.
I'd really like to know when this bug will be fixed.

I was having exacly the same issues with my old build. But since im using CoreDroid this problem has dissappeard.

+1 I've only experience this twice, and not since December, but I found it weird both times. I think both times were during a phone-call. A reset worked.

Wow...another keyboard hero....you are so brave typing that, we are all in awe of how awesome and manly and strong and tough you are!!
ANYWAY......STFU...it's not a screen problem.
I too have this problem, and it is my 2nd HD2 and happens VERY rarely, but does happen and has happend on both of them.
OH, and Mr Tough Guy....I live in the UK...VERY rarely get warm weather over here, so it AINT the sun.
You, Sir = FAIL.

Same here happens once or twice a month no big deal though

I'm currently running imilka's RAM Desire HD v2.0 since a month or so, the pale screen appears sometimes up to 2-3 times on one day and then not for several days. A reboot allways fixes it, sometimes it fixes itself after some minutes.
But i really find it annoying.

This happened to me in most desire/desire hd sense builds.
Now, I use the official hd2 MIUI and gingerbread seems to solve the issue.

Touch sesitivity issue

I bought my Blade 4 months ago and i have been noticing for the past few weeks that the touch sometimes has become less responsive, and only gets fixed until i reboot the device.
I noticed this behavior with SS RLS5, FLB, CM7 stable and a few nightlys. With CM7 sometimes it got worst being almost impossible to unlock the device, my finger goes to the right and the sliding tab goes to the left. And i have to press really hard until the touch responds. After i reboot it all runs normally for a while.
I am running gen2 (since almost i noticed this situation, maybe it has something to do with it...) and i always wipe everything when installing new roms.
Is this hardware failure?
Thanks.

I think when bugs like this happen after flashing a custom ROM a hard reset will fix them.
I think hard resetting after installing a new ROM is always good practice. Fixed my Galaxy Europa up when I upgraded it to 2.2

I don't think it's your ROM because I have the stock Orange ROM and have the same issues. The screen will become entirely unresponsive to touch and only a restart will fix it. Does anyone else have this problem?

How strange, I've had my phone for a while now and this has yet to happen. Too many apps running?
Modaco is probably a more likely place to find the answers you're after.
