About a couple weeks ago I cracked the digitizer(touch screen) on my Lg Thrill and replaced it. Before doing this everything was fine with the phone...I upgraded to GB and it is also rooted but like I said everything was working just fine until I replaced the digitizer. Now every time I make or receive a phone call the phone goes black like it was close to my ear. This only happen if I answer the call and if I make a call it happens right away.The phone is still on and the calls go through but the phone goes black and is useless and I can't even hang it up until the other person hangs up. Not even pressing the power button on the top helps. I have checked and nothing is blocking the sensor on the front of the phone and the new digitizer I got from ebay but again it is a perfect fit and nothing is blocking the sensors...Any Ideas or suggestions? anything would be a great help thank you!

The sensor that the phone uses in order to register face proximity is just to the left of the forward facing camera. Ensure this is connected nice and solid (reseat the wire if necessary) and make sure there is no dust in it as this will likely cause it to behave as it has. Simply replacing the screen won't do this, but improper cleaning before replacing the screen could. You may have to tear the phone down again just to reseat the screen itself.

hmm i had the same issue BUT mine would do it when i cracked the digitizer, which is weird.. replacing my digitizer fixed the issue or it just cleared up itself, try resetting the phone.. Or like zombie said, Tear it down and clean the connectors and sensors

I have taken the phone completely apart and used a can of compressed air to clean it I double checked the sensor connector and made sure there was no dirt or dust in or around the connections. I put the phone back together and made a test call...still doing the same thing
But I did notice that when I made a second test in a dark room the phone did not go black and when I moved the phone close to a light the phone went black....needless to say I am so confused now more then ever. I did a third test and the same thing happened. So any other ideas as to what may be going on??? Seems like the sensor is working no? just in reverse??? Maybe the tint in the new digitizer is too dark? but this still makes no sense as to why the phone goes black when it gets exposed to light. Anyway any other help would be great right about now THANK YOU!

Hey guys,sorry for bringing this up.
Whenever i dial,screen goes black and doesn't come back on.
If i place it flat on a table,then it gets lit but as soon as i rotate the device it goes black again.
My HD7 recently started having this problems...
It started happening after i replaced the micro sd inside with a bigger one.
So my concern is that somehow it moved or got dust when i removed the back plastic cover? Where is it placed anyway?
I tried hard resetting 2 times but nothing works. It would be cool if there was a registry or app to take control of it. Can somebody help?
PS. i cannot send it back because i live in Albania (no official htc shops either around here)
Thanks!
Hello,
The proximity sensor is located on the top left of the device, you can see it when viewed under a bright light. Have you applied any screen protectors which can interfere with them? Replacing the sd card should not have any effect on the proximity sensor. When you rotate the device when the call is placed, the screen should go black by default cause of the sensor
@rhn thank you for your reply.
My phone does not have any screen protector or cover of any kind. Also,if i rotate it while in call it still remains black. As soon as i press the call button,screen goes black and wont come back until the call is ended by the person on the other side.
Really really annoying... Oh sometimes it even flashes after the call has ended...
Sounds like a hardware fault ...have you tried updating your rom?You can find a compatible rom in the rom development subforum..
Yep,tried that too. Just updated today and still the same issue.
It also happened after i changed the micro sd,so maybe something has moved in there. There's no other way than try to open the device and check it out,i guess :/
If you can think of something else,let me know
Warranty
Warranty replacement worked for me.

Thanks bofett, i cannot get a replacement. Warranty for this phone was for 5 days!!! (stupid i know....i totally regret picking it up) So that means i'm screwed...
Thank god i still have my great HD2 so i can start opening this phone without fear
last night my x1s screen was going all fuzzy like different colours and cut out a few times. now today notthing. the screen is blank. backlight comes on i think. the phone starts up normal as i can hear the start up sound and i can accept calls. i think this is failure of the felx cable. Is this true? and if so is i worth get on and fiting it myself or going to a repair shop. im on the cheap here so any fix will do.

I have had the second part of your problem before where screen doesn't come on but the back light and everything else works. A couple of months back when I was at college I dropped my phone really hard at a party( I was wasted ) and the next morning the screen wouldn't come on. So what I did was I looked up the guide to how take the X1i apart and luckily one of my buddies had the same screwdrivers that I needed because he uses it on his the Blackberry Storm 2. So what I did was went to where the Flex ribbon cable was located unattached it, then reattached it, and put my phone back together and the screen came back on and still works to this day. If this helps press thanks.

I just bought a Galaxy S from ebay and am facing this problem. Everything works fine on the phone and it doesnt look like there is any water damage. When I try to make a call the screen goes completely blank. I cannot disconnect the phone or do anything since the screen is blank. The only thing that I can do is remove the battery and install it again. Based on my research it seems like its a proximity sensor. I even went ahead downloaded Z-deviceTest and all hardware seems fine. I also upgraded to the official 2.3.3 from Samsung so I dont have a custom ROM, no root nothing! What can it be? Should I ask the seller for a refund or there are any tweaks for it. Any help is appreciated.

I'm not an expert, but seems related to a faulty proximity sensor indeed...
Sent from my GT-I9000 using XDA App
I am pretty positive that it is the proximity sensor as when I insert the headset calls can be made without the screen going blank. I dont have a screen protector and I tried to put some compressed air to see if that changes anything.
When making a call and the screen goes blank can you cover the proximity sensor for a while and see if its turning on the display? I kinda have the same issue sometimes and covering the sensor would normally do the job.
Sent from my SGS using XDA Premium
Same problem here, seems that plugging headset does the job. It is kind of lose or lose situation, even turning off (any idea how?) proximity sensor would not help as screen would be touched by ear Any other solution anyone? Or some kind of calibration? Check? Most applications from marked I have checked are crashing or showing 5cm from sensor regardless.

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!
Hello fellas,
I replaced my note 5 lcd before 4 days it was working perfect w/out any flaws but it suddenly went black while using it was full charged while it happend. but i can receive calls texts hear sounds. I tried a youtube fix by holding Vol down+Power!! Yes it does reboot the phone but whateva happens lcd is black, even i tried to flash stock rom also its succeed!!
I dont know what the problem is but my lcd was broken before, while in that stage it cannot boot or receive calls there was only a solid blue led.
But in this case i dont know what the problem is and i think you might help me figure out.
Thanks.

I had the exact same problem and unfortunately the phone had to be replaced under warranty so if you don't have a warranty on the phone then immediately contact whoever sold you the screen and get a replacement since that one's broken. It's not going to come back no matter what and it was probably a cheap knock off which is all I keep seeing all over the place but try anyway because they aren't cheap at all!!!
Sounds like when you had the LCD replaced they didnt do the digitizer ( that is the component that converts the signal to pictures for display on the screen) usually when one is damaged they are both replaced at the same time

I think you're a bit confused on what a digitizer is... It's not for converting pictures it's for dealing with the touch part of it I.E it senses where your fingers are on the screen.
