Hi guys,
First of all I'm amateur with this stuff.
I bought my HTC Desire 500 last year, everything worked fine until 15 days ago - it was on vibration but there were no vibrations, just like silent mode instead. I dont know how and when but vibrations stopped working. (Yesterday he vibrated all of a sudden, bjt instead of vibrating 3 times he vibrated for like 2 seconds and it sounded like someone is torturing my phone, like he is trying to vibrate but he lose contact or somethin') Few days ago my battery was very low so I turned it off. In the morning I charged him and I wanted to take a picture but it opened my front camera. I tried to slide to main camera, but I couldn't. I've opened my camera settings but no effect. I've tried with other apps but my phone don't recognize my front camera at all. Likenit doesn't exist at all! Yesterday I couldn't recieve any text messages and today no one could call me! He turns off my wifi every 10 seconds, then it takes time for him to connect me, it zooms stuff all by itself.
I downloaded 3 apps first when I bought him and I've disabled few apps I dont need, but I did all of that first day I bought him.
I bought this phone because of its fantastic camera and now it doesnt work.
It's not rooted, I've tried hard restart, factorymode but nothing.
Please help

Hey guys, I was wondering if somebody would be able to maybe help me diagnose the fault\problem part with my non-working diamond...
Basically I went to a club one night and the place was unbelievably steamy / humid. My phone was working one minute and then the next it wouldnt display anything on the LCD. The backlight was working however.
Since then I havent been able to get an image on the screen although when trying to turn it on, it seems to go through its startup sequence (backlight -> vibration -> beep (i think))
I havent had any power to the phone since a day after it broke (a few weeks ago).
I'd like to get it back working again but dont know exactly what part i would need to replace. I'm fairly competent with electronics .
Any help/advite would be appreciated!
Haha, ok that's odd...
I've plugged it into my pc to get some data files off about an hour ago.. forgot about it and just looked at it now and the screen is displaying!
It is displaying and accepting input although it was flickering at first (like pixel shifting). but i pressed the power button to standby the screen and pressed it again and the display is fine with no flickering ?
Ive moved the phone about and shook it quite hard to see if there's any loose connection but the display still seems fine..
Anybody have any ideas as to what it may be?
I'm not going to deem it as fixed until I know what the problem was/is lol
cheers guys
Ok screen actually keeps flickering nonstop, and sometimes 'fades away' to gray/white/black
comes back after a few seconds though
Looks like a faulty connector?
Hello
One night I was using the phone without doing anything special , some video watching . Phone went dark, tried to reboot. Blank Screen and the capacitive buttons flash. Left it to charge all night, in the morning it started but after I pressed the lock button blank screen but phone still working and receiving input.
Took the battery and SD card out left it for 30 seconds then started it again, Stuck at LG logo. Repeat , phone started ... Pressed lock button once then again to unlock , screen wouldn't start.
Used LG Mobile Update recovery tool to restore it ... Didn't solve problem. Sometimes it does not even start , just flashes buttons, other times it does without screen and last all works even the screen until first time goes dark , in the last two cases I can use LG On-Screen Phone without trouble, in doing so I installed a proximity sensor test app to see if it was causing my screen to not come back on , the sensor looked fine.
Facts:
1. Two day old Optimus Black p970, worked like a charm until stated problem
2. The app that checked proximity sensor showed the sensor to be free when my hand wasn't on it
3. The warranty laws in my country are idiotic so I would do or buy anything rather than send it so they can give me a new one in 3 months.
4. Tried another battery from another Optimus, fully charged nothing different.
5. Stock rom.
Do any of you fine people have some ideas on how to fix this? Thanks in advance
Hi there...
Sometime ago [1 year and a half or so~] I worked at a cell refurbishing facility [there were samsung, motorola and palm devices from sprint] and that problem you have was quite usual. Blank screen, still the phone is somehow usable like reciving calls...
There's this thing called "flex" which is the connector between board and display and that is what we fix, most of the time not even "fix it" just getting it in the right place...
This happen because of excesive use in those sliding or clamshell devices, in OB could be for overheating, you could try to fix it yourself or pay $20 usd [that's what it cost here]
Would that connector explain the fact that sometimes it doesn't start at all? hmm I am thinking now and I guess if it moves and somehow the phone feels it has not display connected it could fail to start... Anyhow thank you
actually yes, it could be only for the flex [some devices don't start at all when not having display or keyboard if there's any] but since our OB is not sliding nor clamshell type probably was overheating.
you say you have stock rom, well now I'm using CM7 but when I was at stock and after using the phone a few minutes it felt warm and some more minutes [like playing gunbros where you need to use both hands and a lot of movement] it was really hot and had to stop playing for a while.
what I'm trying to say is that because of overheating flex could have moved, but because of overheating too may have move something else, you couldn't belive the huge number of micro-things that reside in the board.
so if it's only the flex, it's an easy task to do, just unplug and plug again, but if it's something else it's quite hard to know just looking at it, you need to do some electric measures and stuff, the recomendation is to take it to a tech center or something

Hi there, got the same problem too with my optimus black. Screen goes flickering, shut down don't do any good, and the phone temperature is kinda hot. But in my case it work after I clean some cache and data in the phone storage through LG OSP. After that, the phone temperature back to normal and the phone screen back to normal also. I believe that in my case the phone is overheated.
using HTC Google Nexus One, Android 2.3.4
This is very strange, but I noticed today that my camera is no longer working. I have no idea why, but it just goes black when I select camera. I have restarted my phone, took out the battery, etc. and nothing. Also, I even tried downloading other camera apps, and they won't work either.
Even more frustrating, though, is that my phone goes black when I make or receive a call. The calls do not get dropped, but when the call is over, I can't even hang up, as my screen is black. It's weird because my phone is still "ON," but I obviously can't do anything. The only thing I can do is take out the battery, put it back in, and turn the phone back on. Then, it works perfectly normal...until I make or receive another call. I have no idea what to do.
Can anyone help? I'd really appreciate it, as I use my phone for everything!
Hi,
I had very similar issues after accidentally dropping the phone (landed exactly on its face) . The sensors no longer worked, nor the camera and the flash light.
The problem during the phone calls is most probably related to the defect of the proximity sensor. However, I managed to use the phone with a bluetooth headset. The screen could be turned on any time, and, of course, I could terminate the call using the headset's hardware button. I used my N1 this way for over a year...
Few weeks ago I dismounted the phone, and realized that upper motherboard's connetor was detached from the main motherboard. After fixing it, everything is fine again.
I followed instructions from here: http://www.ifixit.com/Guide/Installing+Nexus+One+upper+motherboard/8025/1
I hope it helps.
Cheers,
Zoltan
Thank you for this thread
I created an xda account just to post about how this helped me.
My Nexus One camera had stopped working, auto-rotate no longer worked, and my screen was remaining dark after completing phone calls. So annoying. Was about to pony up some money for a new phone.
BUT... I followed the ifixit instructions that Zoltan posted above to take my phone apart, and low and behold, I had a loose connector. Plugged it back in, reassembled my phone without breaking anything, and it works! I have camera and auto-rotate again, and my screen acts normally when making phone calls.
Thank you!
Hi,
Have not posted in here in a while but i'm having a huge problem with my HTC one M7.
Had the phone for a year now and suffered a problem with it once before. The problem before was something to do with the phone locking itself and required me sending it off to HTC to repair. It kept bootlooping and wouldn't allow me to do anything at all.
This problem hasn't occurred since repair however last week the phone was working fine until the next morning when i woke up. My girlfriend used my phone to send herself some photo's and then put the phone on charge as the battery was running low. When i woke up the screen stays black and wont allow me to do anything. If i hold the power button the bottom two lights flash and i can hear the phone booting itself back up. I have a feeling the phone works since everyday at 6:15pm my alarm goes off and i am able to deactivate the alarm by swiping up (i remember the location of the dismiss function) it would appear i'm also able to receive calls and texts since i can hear my message and ring tone going off however cannot see the screen.
I have tried a few things such as holding buttons to reboot, shining a light onto the sensor during a reboot and fully charging etc however nothing.
I should also add i have a slight hairline crack in the screen which occurred about 9 months ago but didn't appear to affect the LCD at all or the digitiser either. Any help would be highly appreciated or any tips on stuff to try.
more information available if needed.
Many Thanks
Kris

It looks like you tried all of the usual methods, sorry but it might just be the screen is shorted.

I thought as much, i have ordered a new screen and once its delivered i am gonna attempt to fit it and see what happens, thanks for the reply.
When opening the camera app, occasionally my phone start vibrating. It doesn't happen all the time, and the vibrations aren't always the same length.
I just got the vibration once, and 4 out of the next 7 times opening the app it vibrated in varying amounts. Of course this affects the picture. After these 7 times opening the app the problem stopped.
This has happened to me on multiple occasions, and I have not found a reason why. I have Smart Alert on, but I tried turning this off in the middle of the 7 retries and it still vibrated afterwards.
Does this happen to anyone else?

its the camera senor. it is normalizing from what i read. happens to me too on snapchat and the regular camera.
So this is normal behavior? I have not experienced this with other phones.
Happens to my phone as well when using the camera app

Mine has been getting worse and worse lately, when I shake the phone front to back I can hear the camera make a tapping noise like something's loose. It's starting to vibrate more often when starting up the camera app.
When it stops everything works fine, I'm not sure if exchanging it is worth it since I'd probably get a refurb. I've had my phone for 37 days.
I'm having the same issue. I see it on other forums too.
ro.ril.sensor.sleep.control=0 In build is supposed to fix it, but not for me.
