[Q] Camera Freezes/Black Screen/FC, anyone fix HW on their own? - Sprint HTC EVO 4G LTE

I've been trying the past two days to get my camera stable. Regardless of the rom I am on, sense or aosp the camera will work maybe 1 out of every 15 tries.
It will either freeze, go to a black screen, force close, or state that the camera cannot be connected.
I have even opened the phone up and reconnected the ribbon cables at the mainboard although nothing looked loose.
The only thing I didn't do was try the camera when I first got the phone (before rooting and loading custom roms), to see if the issue existed at that point. I have however tried the camera with the stock variation compatible with root.
I've looked at a lot of posts on the subject and most of them seem to end with the OP getting it fixed under warranty, which I do not have.
Has anyone with this problem (most likely hardware related) solved this problem on their own, maybe by replacing the camera or another component?

[Q] Spastic touch screen

My touchscreen has been doing some weird things for a while now. First of all it just stops responding altogether and a temporary fix is locking and unlocking the phone. The second issue is the screen taking a mind of its own and pressing itself to which I can only watch and hope that it stops. I thought these two problems were software related but I've flashed a few roms and kernels and have factory reset the phone too, yet they still exist. So does anyone have any solutions or has had similar problems? The annoying thing is that the issues happen on and off so there's no solid way of showing it to my carrier so they can give me a replacement phone.
I had the same issue, only while charging my phone. Seems like another bug or something

try wiping the phone's surface with very slightly damp cloth, it could be the dust & water causing all sorts of problems. make sure its clean. If it continues, contact the LG service. they MUST fix that kind of error. but get rid of your root
It's a hardware problem (touch screen)
I had exactly the same problem. I've sent the phone in for repair and had the touch screen replaced. Now everything is working fine.

[Q] Another Digitizer Thread or Maybe Different One

Hi, I have a quick question.
My digitizer starts failing. I know in the end it should fails cause most of them need to be replaced but maybe my problem is different.
Most of digitizers are stop working at all or only some parts of it. My digitizer is working fine but ONLY after turning on screen sometimes it's working like using it with wet fingers - it's crazy pointing everything without my control. After turn off and on screen it's working fine until next turning on.
I'm wondering can it be software problem?? I had similar problem in Defy+, leds under hardware keys stop lighting and before sending it on warranty I wiped it and now all working fine.
It's no problem for me to replace digitizer or wipe system but it would be good to know that it can be software problem before buying new digitizer.
Maybe you need to apply the raindrop fix. Been discussed already.
First, thaks for understanding what I mean. (Very poor english)
Second, this is exactly what I ment. I just copied tounchpad.cfg from http://forum.xda-developers.com/showthread.php?t=1467696 and all looks fine now. No mess up on multitouch. I hope it will stop messed up touch while turning on screen, need to test it for a while cause this issue isn't appears on each turning on but ocassionaly.
Anyway thanks for fix. You saved my time (3 hours on wiping and bulding new system) and money on new digitizer.
One more thing. I'm using this phone from few months and everything was ok. The problem appears few weeks ago. So if it is bug in rom it should appears just after I bought it, not after few months. Or maybe it's not factory bug but just error in touchpad.cfg??
Sorry for post under post but I have few more informations.
After testing few days raindrop fix the problem still exist. Fix helped but not fixed problem. Still after turning on screen touch is acting crazy but after first touch it stops and before applying fix it stops only after turning off screen and turning it on.
I reflashed full sbf stock Gingerbread, full wipe including internal memory and still the same problem.
Strange thing I observed is the problem appear only when WiFi is on and it's searching or trying to connect. When WiFi is off or it's connected to router the problem never appears and when I turn on screen and after that turn on WiFi everything is ok. Only when I'm turning screen with WiFi on screen touch acting like crazy.
Is there any chance to fix it or should I buy new digitizer??
Ok, I changed digitizer on warranty and now everything is okay. Funny thing is that I have unlocked bootloader and they changed my digitizer without any problems. Less funny is that they broke both sensors changing it and I had to send My Atrix to Motorola once more after two days to change flex. But now I hope it should be working fine.
So after all it had to be popular hardware problem.
Thred can be closed.

Very strange crash every time I use my phone

I can leave my phone plugged in and charging and quickly check a text message and reply, and my phone will be fine. But if I try to use my phone any more than that, the display gets strange artifacts (it's different every time, ranging from a dark grid overlayed on top of the image to the screen filled with different colors on each pixel) and sometimes the speaker emits a constant loud high pitched noise, even if it's on silent. I noticed one of the times that the sleep button worked, but using the touch screen and the capacitive buttons is impossible and I have to yank out the battery every time it happens. I'm running a recent CM10.1 nightly and default kernel, and I've experienced this problem independent of which nightly or kernel I'm using for the past few weeks (I have had no problems in the recovery menu). It even crashed one time upon boot up when I tried to unlock the phone immediately. Another minor problem is that my home screens got screwed up one of the times it crashed. It seems like a hardware failure to me. I'm wondering if anyone has seen this problem or has any ideas that might help. Thanks.
It certainly sounds like a hardware issue to me. I have not seen anything similar reported on these forums. Is the phone currently stock, or custom firmware? The best test to see if the problem is firmware or hardware related is to flash a fresh stock firmware using Odin3. If the problem goes away, then it is obviously a firmware issue.
If it is a hardware problem, you may have trouble flashing a fresh stock firmware, or may not be able to at all. Or if you are able to flash a new stock firmware, but the problem does not go away, then it is probably hardware.

[Q] [HELP] [URGENT] Xperia Mini Pro Touch Not Working

Hey Guys,
I am having a big problem with my device. The touch is not working. I have been flashing various roms on my phone and after playing with many roms, i finally flashed stock rom into my phone and flashed a stock ics based rom. Everything was working fine until one day my touch was not working well. I switched off the phone and turned it on and the touch was right back on. Again, things were smooth until this issue happened quite frequently. The problem was solved after turning off the phone and powering it off. After some time, the problem again started to come. At this point, the touch was not working COMPLETELY.
I was scared and immedaitly flashed the stock rom. During the initial boot, everything was working fine. But, when i locked the screen and tried to use the phone after some time, the same problem occured again.
So friends, my question is, Is this a software related problem or a hardware related problem. If this is a h/w related problem, is there any point in touch working during some time and not working later? ( Now, touch stopeed working completely). Will any tutorial on this forum about bricked touchscreen (after flashing wrong rom, which i am sure i didn't) will help me solve this problem?
I am awaiting for your valued input as this is the phone that i use for all my communication needs.
Kindly help me
Thanks
Well, if stock didn't solve it, there's a chance it's a hw issue. If you look closely, "touchscreen brick" guides are meant for the mini and the lww (touch digitizer separated from display), not the mini pro (touch digitizer and display as one assembly).
And yes, there are situations where your touch digitizer might cease to function for a few seconds then respond after a while, and sometimes it stops working completely after the next reboot (or forever). It happened to me with a deffective replacement part.

Thanks for your reply.......
I guess it is indeed an hardware issue. My phone used to reboot when i slide my keyboard out fast. The screen gets dimmed out and the phone immediatly restarts. Last few days before the problem worsened it was overheating also.
Can you suggest me which hardware part i should change to rectify the touch issue? Awaiting for your reply
Thanks a lot
Ok your problem seems to be worse than expected. A faulty touchscreen shouldn't cause sudden reboots. I'd say it's a flex ribbon issue.
Try to get a replacement flex ribbon and test it extensively before installing it on your phone. Replacing the flex might be enough to solve all of your problems. If any of the problems persist with a new flex, you'll need a new screen assembly (quite expensive at 35~50 bucks).

Camera problem

Hello
I had my phone in a drawer for over a year because the lcd shattered and a few months ago I ordered a 'new' screen and replaced it.
The first time I opened the phone I broke the front camera flex cable so I ordered a new one also.
The reason I'm giving a little context is to give you some insight to what could be the problem.
After replacing the front camera, it wont work. I tried installing the original stock rom, updating firmware via mmi codes and cleaning the connections.
What happens is, when I open the camera app (tried multiple ones of course), the back camera behaves very strangely and when I switch to the front camera, the phone either reboots or the app freezes.
This behaviour is green and purple lines through the image when opening, it kind of pulsates and if I get it closer to something bright it takes a few secons getting to a normal clear picture.
This is a recording I've made with the back camera: streamable.com/ilxln
Would apprecciate any info on this.
Thanks
