[Q] Display Problem - LG Optimus Me P350

Hello to all. I have one thing to ask you. I realized that when I replace in my terminal a ROM like CM 10.x or derived, the screen starts to behave abnormally, with a sudden flash or white lines that delivery from the lower end of the screen until the upper end.
This is normal? I do not think, to avoid damage to the phone, however, soon after verifying the occurrence of these phenomena I immediately replaced with a different ROM.
What causes do you think? No one has had the same problem?

Issue w/ Screen during phone calls

After flashing the DeFrost series of ROMS (I am not saying they are the cause of this issue..) from 0.8 to 1.0 ---
I've got an issue where the screen switches itself off during a phone call and never turns on again, unless I pull out the battery and reboot it.
I've just tried flashing Pays BS and RS ROMs and they still to have this issue?
Could it be a problem during flashing just screwed over soomething inside the phone? (Prox. sensor maybe?)
Thanks for your help.
*****EDIT****
I've just found out that if i place the handset (whilst during a call) in very bright sunlight or bright artificial light --- then the screen does re-display.
It's strange however, I'm outside during midday and the screen still is off whilst placing a call. It only registers that the phone is away from my face near a very bright light source.
I've found this issue is faced by many people usually after ROOTing their device(s).
A 'USB-Brick' like issue possibly? (Proxy-Brick lol)
I will attempt to hand in my now HBOOT 0.80 ROOT'd desire to Telstra for warranty tomorrow.
I am now pretty sure that this problem is random and occurs when rooting/flashing a cust. ROM through recovery.

[Q] Weird input problems

Hi,
so I am finally at that point where I'm about to jump off a bridge.
My beloved HTC Desire has got weird problems and I really have no more idea, what I can do.
So here's the problem:
Sometimes (turning screen off sometimes helps), my phone registers an input (at a certain horizontal line, I will clarify that later) when I'm actually not touching that zone at all.
So (if you have the keyboard open), it always thinks it is touched at a horizontal line which is about there, where the 'a' is on the qwerty-keyboard. (I have a swiping keyboard on my phone, that always gives a nice blue line from 'a' to 'l'...).
The really weird thing about that is, that I don't actually have to TOUCH the screen. I can move that blue line on my keyboard (or change homescreens for that matter) while I am about 1-2 cm ABOVE the screen and I DON'T EVEN TOUCH IT. That really drives me crazy, as I don't even know whether that's physically possible...
That behaviour is totally random, sometimes I don't see it for 1-2 days, sometimes it won't go away for a couple hours.
Additionally, sometimes the Screen won't recognize my touches at all (only at lockscreen, turning on and off helps).
So I tried restoring various Nandroid backups from when I didn't have that problem, I tried flashing a new radio, a new rom, data, factory etc. wipe and nothing helps.
Pulling the battery when it's off and leaving it off for about 10min also won't help.
If you don't understand what I'm trying to say (I know it's difficult and I appreciate any efforts to help) I will try to record a video of it.
It is also difficult returning the phone as that failure is not reproducible.
I am running MIUI 1.5.20 on my S-OFF'ed HTC Desire with SLCD Screen.
I would be so thankful for any help,
Don
Maybe just an issue with the screen in general. You ever throught about contacting HTC or your carrier? See if getting a new screen would be better and stop these problems. Just be prepared to use an RUU though.
thanks Meaple,
anyone else got an idea?

[Q] DHD Display flickering; How to repair?

Hello Forum,
seems that my DHD has an irreparable error.
But i've still a little hope that maybe someone of you guys out there can point me into the right direction to repair the phone again.
What happened:
on December, 20. for no apparent reason the Display started flickering approximately 2 cm from the top.
The upper Part (the first 2 cm from the top of Display) was showing the normal Picture, on the lower Part the Picture was flickering at irregular time intervals, but the touch gestures were still working without any Problems.
Setup at that Time:
- Latest 4ext Touch Recovery
- Latest MIUI.us Rom by bliind
- Custom DPI set to '190' (with ROM Toolbox)
- Max CPU Speed set to 1200 Mhz (with Set CPU)
(Had this setup working fine without any issues for approx. last 2 Months...)
Last change i did before the error occured: Set Custom Boot Animation with Rom Toolbox
The Flickering started not immediatly after setting the new boot Animation but i think 2 days and some reboots later...
Actions that i've already tried to solve the Problem:
1. Shut down the Phone, pull out the Battery, wait some Minutes, reboot the phone.
-> The flickering was gone and the Display looked normal after reboot.
2. After some time I took the Phone out of my pocket and the flickering was there again like before.
Tried to set DPI back to original value '240'
reboot the Phone
-> The Flickering still was there and it seemed to me that the responsiveness of the touch was slightly slower than normal.
3. Reboot into Recovery
Nandroid Backup all Partitions to SD-Card
wipe all partitions except SD-Card
new, totally clean flash of latest MIUI.us Rom by bliind
Reboot the phone
-> The flickering was gone; responsiveness of the screen normal as it was always before.
4. restore all apps; put the phone on the charger over night. everything worked fine again.
on the next Morning this strange flickering was there again; the Touchscreen was very slow responsive in the flickering area
Managed once more to reboot into recovery, but the flickering was now even in the Recovery and on the boot screen.
-> The Touch got more and more unresponsive.
Could no more start a new ROM flash out of Recovery.
5. Tried to access the phone via aahk tool and restored last stock ROM
-> After Reboot the DHD vibrates (like it usually does for startup)
the screen shows a bunch of black and white Stripes that chnge their Color when the Boot Animation should show up,
and later again when the lockscreen should appear.
It makes the boot jingle and i can send Commands via adb.
but Touch commands doesnt work, (tried to put in the Pin blind, but it shows no reaction)
Stupid, but I can't change it: my Warranty and the extra Insurance that i purchased for the DHD ended just 2 weeks before on 6. December.
6. Disassembled the whole phone with Help of you tube disassembling Guide, carefully cleaned all contacts and assembled it again.
-> nothing changed; same behavior like before disassembling.
What can I do? Any ideas except of small rasping and stirring into the soup? :crying:
Can it be only the display? Maybe the Graphic Chip?
Any other ideas?
thank you for reading this all and i appreciate any suggestion that might give my DHD a new spirit of life
Greetings from Cologne
I know it's not what you want to hear, but that sounds like a graphics or display hardware problem...

Thanks for your reply!
That was the same what I thougt after disassembling and cleaning with no result.
Cause it seems to me that the Display is still working, but the Signal that's coming in is broken.
I alsready supposed that the Graphic engine is broken.
Just had a little Hope that someone might had the same Problem and got it solved,
before I start practice for mobile phone throwing competition...
i suggest another ROM JB used to cause my DHD flickering (earliear versions)
My DHD was with same problem 1 year a go, and that usually happen when i played games like Angrybirds or Asphalt, or when the device temperature was high.
I was worry at that time, thinking that the device was gone.
Take the same solutions that you had (except disassemble the phone) but they're only temporary.
By that time i decide root the device and install a new rom, (nothing to loose had i think) and Revolution HD was my choice.
After that my DHD didn't flick any more.
I didn't ever know what was the origin of that flickering but for me, that was the big solution.
I'm using Viper Venom 1.2.3 for now, and still with no flickering insues.
So, my advice for you is... give a try to other rom's and kernels, maybe you resolve your insue has i did.
Good luck with that.

Thanks for you Answers guys,
the Problem i have is, that my DHD does show only sripes even if I try to boot into Recovery, I can't see anything and am not able to start a flash process...
cause i have installed 4ext touch recovery i need the screen to wipe and flash a new ROM.
But i will try to flash an CWM - Recovery through ADB and then to start the flash Process blind by tapping the buttons...
let's see what will happen. There's nothing to loose...
For now, cause I was sitting without a mobile phone at all, I've ordered a cheep one from Amazon... - Huawei U8510 (Ideos X3) -
And oh WONDER!!!: I've got a fully functioning phone with CyanogenMod 7.2 and all the stuff i use my phone for is working without any Probs..
And the whole thing has 2 years of warranty at a cost of € 80,-
only the Display for my HTC would cost € 40,-
so I'm thinking of selling the broken phone on ebay and let anyone try to repair it who is able to....
but I will give it a try to flash another ROM.
Already downloaded the JellyTime R30...
Hello unbeteiligter,
seems that my DHD has nearly the same issues, but with some extra problems.
It seems to be broken since today morning. I wiped the phone and restored the backup I made the afternoon before, and then the first vertical stripes occured. I wiped it and flashed the same rom (CodefireX 4.2.1) again. Same issues. Now I tryed to flash a GingerBread Strock Rom. Even the same issues, and even more shocking is that this problem also occurs in the bootloader, recovery, splashscreen and bootanimation.
Stupid situation, today my Warranty ended.
What can I do? Previously I tougth this is a software problem, but now I think it might be a hardware issue.
Thanks in advance!

Seems to be the same like my DHD. But for me it ended up 2 Weeks after end of Warranty!

The T-Mobile Customer Support told me, that they would have accepted the case as Warranty, if my DHD had ended up during the first week after End of Warranty. Don't know where you bought yours, but maybe there's a small chance for you to get Warranty Support through their obligingness.
If I were you I would try this...

If your dealer don't accept your Warranty Call, I can't give you much Hope... Sorry for you...
... would imagine you should look for a new phone...
That's what I did....
Similar problem
I have also got a similar problem. Had my phone for two years and have also just hit the same problem. Flashed a new ROM, everything was working fine, then all of a sudden top half of the screen is displayed correctly, the bottom half is always flickering. This occurs in the bootloader as well. Anyone would think that HTC decided to make sure the phone only works for two years and a few weeks after the warranty expires to make sure it experiences problems.

[Q] modded/rooted One X screen issues: hardware related?

So, recently my One X (EU version, endeavoru) begin showing some problems, as outlined below. It was the newest stable CM (10.3) and a somewhat older version of CWRM. After the problems showed, I managed to upgrade to the latest CWRM and CM. Here's the problem:
- When I tried to unlock my phone, the screen stayed black, so I reset the phone.
- When it started up, the HTC logo looked fine, but the CM logo was shifted down and banded: the top of the circle was visible on the bottom of the screen and the bottom of the circle on top of the screen. After that logo the screen turned black.
- It DID boot though, as I could feel the haptic feedback when trying to unlock, and I could hear the sounds of making a screenshot (power+vol down).
- After some resetting etc I finally got an image of the screen again, and saw that I moved some widgets around, so the touch screen def. works when the screen was black.
- I wanted to make sure it was a hardware problem, so I did a total wipe (factory/dalvik) and flashed a new recovery. This worked, but a few times when working in recovery the image froze. I'm not sure if the recovery crashed and did not respond to input, or that the screen just froze, as CWRM only has visual feedback.
- I managed to install the latest CM, tried it, it worked, and then the screen showed some green lines, and a slight shift upwards (the top rows of the status bar showed at the bottom), and I couldn't do anything anymore as far as I could tell.
- The bootloader also showed some problems: the letters were enlarged and overlapped while the image was also smeared across the screen.
Now, basically my question is: can I be sure this is a hardware problem? HTC will fix it if that's the case, but otherwise I will have to be a bunch of money for nothing, because then they will pin the problem on the custom software/firmware/recovery installed. However, I don't think any of the firm/software can actually influence the bootloader, am I right? So if there are problems with the bootloader, it cannot be the case that something I installed on the phone causes the problem.
i think what u have there is Screen Flickering ,, and it's due to a hardware problem ,,someone had the same problem and he had to replace the screen and the motherboard !!!
again am not sure !!

Thanks! I searched for one x screen flicker and found a video that showcased my problem perfectly:
youtube.com/watch?v=BfnwMFtD2_A
One of the comments said that if they pressed the screen just below the HTC logo it worked again (temporary), and I could reproduce this on my phone. Now I have no doubt at all it's a hardware issue, and I will contact HTC for repairs!

Desire 820 (A51_UL) - strange touchscreen problem (fixed?)

Hello everyone
I bought this phone used for an attractive price, the seller said that the touchscreen became unresponsive "after their son installed an update"; what happens exactly is that every second touch or so is ignored. When I begin dragging and it doesn't get ignored the drag never gets interrupted as long as I hold the finger down, so it's not the touchscreen connection dropping at random. I unlocked the bootloader and put a matching Lollipop RUU on it, then updated to latest MM through OTA, installed TWRP and SuperSU - the touchscreen problem never disappeared, not even in recovery. After that I got the digitizer completely replaced... And the new one does the exact same thing.
This is probably about the same problem: https://forum.xda-developers.com/desire-820/help/htc-desire-820-touch-issue-t3398027
There seem to be many others all around the internet with the same thing happening to them, often after an update...
Does anyone have any clues? I tried everything I could think of and now I'm at a complete loss.
EDIT: After taking the phone apart and putting it together one more time, the issue is mysteriously gone. I'll keep this here in case anyone else gets the same problem.
