After phone call, screen is off - Epic 4G Q&A, Help & Troubleshooting

when a phone call is over and I want to click "End" my screen is off. I have to open the keyboard to get the screen back on. Doesn't happen all the time, but quite a bit. Is this a bug or maybe the way I am holding the phone?

The epic has a proximity sensor onthe top left of the front of the device. To the left of the sprint logo. If your hand is covering it, the screen will stay off.

Thanks. Will pay attention to that next time I make a call.

[Q] Optical Trackpad Issues

Is there anyway to disable the optical trackpad? as it is always activating on its own
What do you mean "activating on its own"? You mean the phone wakes up when you press the trackpad? Or when you merely touch it? There should be a flashable patch for your ROM that disables trackpad-wake. Search the thread for Virtuous G-Lite.

He means that it activates and selects things on screen on its own. It happens when strong light beams across it. The trackpad activates as if you've moved your finger over the surface because it is sensitive to the light.
Oh, really? I never heard of that! Now I'll have to try it myself.

Try sitting in the passenger seat of the car with the sun somewhere over your shoulder. Flickering sunlight does weird things to the trackpad.
Oh that is just cool. I have an LED flashlight on my key chain that is insane bright and I just shown it on my trackpad and it starting jumping around my home screens.

lol I could get over having trouble seeing it in direct sunlight I just bought a anti glare screen protector but this makes me want to throw my phone out the car window sometimes
What if you cut that anti-glare screen protector to fit over the optical trackpad. Maybe that'll diffuse enough light to stop the sensor from going wack but still sensitive enough for you to still use it with your thumb?
I can't get the effect to happen. The most that happens is the active icon selection on my home screen moves over one icon. No crazy jumping around on mine. Anyone want to trade me for their "defective" phone?

My phone ain't defective ... its "magic"
Sent from my HTC Vision using XDA App
got the same issue. especially when in the car. the most annoying bit is when i have my sat nav on, and the trackpad plays up, the screen starts moving off course! not helpful when aproaching a roundabout!
have had my desire z for 8 months now, and tried to live with it, but its just too anoying now. so thinking of returning it, but if its a common issue, wondering if they would be able to fix it?
anyone returned theirs to have repaired? did it work?
I don't think it is repairable it is just the trackpad is to sensitive if only there was a way to disable it via software:/
well there are those who say that they dont have the problem, so i guess theoretically, its a fault with many of them. unless they havent used their z in the sun!
i think i'll take it back, as it obviously shouldnt do that. if they cant repair it, or replace it with one that doesnt freak out, i'm gonna change to something else..

Slightly broken Xperia Play, help?

So I bought a brand new Xperia Play from eBay. I assume that it is covered under warranty.
However, the other week I dropped the phone. The LCD Screen is not completely cracked! What is disgraceful is that the drop was not even from a high height! Such a brittle piece of plastic!!
The strange thing is, although the phone still works, it seems to run a little bit more sluggish. I'm not sure. The BIG problem is, when I begin a call, my screen turns black, and once the call is finished, the screen won't turn back on again (Even though I can hear sounds through the speakers). If I press the lock button quick enough before ending a call the screen sometimes turns back on.
I was thinking about buying a new LCD screen from ebay for £20, however I'm afraid that it won't fix the 'screen turning off during a call' problem.
What would be the best way to get this phone repaired?
Any help would be much appreciated, thanks.

Maybe you damaged the light sensor on the screen?

Maybe you damaged the proximity sensor?
If the proximity or light sensor was damaged, how would this make the screen switch off during a call, not turning on again?
Does anyone know the best route to get this repaired?

Replace the front glass. Maybe you didn't destroy the proximity, but just damaged it to behave in that way. Also, broken glass is also maybe affecting it.
Thanks, I'm going to buy a new screen then. God knows how long it will take to ship, but I will keep you guys updated with pictures as soon as progress is made.
Mine was doing exactly the same thing after shattering the glass. The proximity sensor could not see through the cracks and the IR light would refract back in as if it were against my face. It behaved strangely where sometimes opening the slider would snap it out and other times it would not. Replacing the glass/digitizer did the trick. The only problem was that no replacement parts on eBay include the adhesive gasket and the old one is likely ruined with stuck-on glass shards. I pulled off as much as I could and reused it but me touchscreen doesn't stick all the way down sometimes. I ordered a dummy phone to see if I could salvage it from one.

The screen is designed to switch off during a call if it detects you face next to the screen (proximity sensor) if it is damaged and reporting wrong info to android. That is why the screen switches off during call.

The sensor is fine. The glass covering it is not.

[Q] Black Screen - My gf dropped her phone

Hey guys, my girlfriend dropped her Sprint Samsung Epic 4G that I rooted for her.
It hit my tile bathroom floor, and when she picked it up the screen was black.
Everything else seems to function. It turns on and off, she can even unlock it without the screen showing up, and can hear sounds, but the screen is completely black.
Any advice on how to fix a black display screen?
Thank you!
Edit: We just noticed a small crack in the right hand corner of the screen. Also, the menu buttons do light up, and the phone does receive phone calls and text, as we can hear the noises and use the touch screen to some degree.
Your in luck.. could be a loose connector.

Checking it out. Thank you.
Appears as though the screen itself is broken under the glass. Took all of it apart, except for the very last part.

Proximity sensor causing major problem

So this is my second S3 with an identical proximity sensor problem (phones are/were both completely stock) - hold it to your ear and the screen blanks like it should but lower it so you can enter a keypad number (like for voicemail) and the damn screen shuts off as soon as your finger comes near it! WTH? This is insanely frustrating but I haven't read of it happening to others nor did Telus tech support. Am I the only one to have this happen to (twice)?

When you hold the phone down from your ear, putting your hand/fingers anywhere near the top part of the phone will cause the screen to turn off. The sensor is just to the right of the speaker, to the left of the front facing camera. It can be a bit frustrating at times, but just taking your time and making sure not to go too close to it is pretty much all you can do.

This just seems a bit crazy to me. Some of the numbers I need to enter for my voicemail password include those that are on the top row of the keypad which is apparently close enough to the sensor to trigger it and blank the screen. I guess that explains why I have better luck with the numbers on the bottom keypad row. So the only thing I can do is hold the phone on the very bottom and very carefully slowly reach up with a finger and very gently tap one of those top-row numbers? That just seems too bizarre to be true - but I'll try it.
Hm, ive never had mine do this while typing. It does turn off if I put my finger up there but I've only done that on purpose, to test it. Never blacked out the screen on accident. Makes me wonder how differently you hold your phone than I, or maybe your proximity sensor is much more sensitive.

I don't think I hold the phone in any unusual way, I just hold it around the middle with my left hand and use the index finger of right hand to (try) and enter a keypad number. Sometimes (maybe about 1/2 the time) it works without an issue but when it decides to turn off the screen it can take me many tries before I am finally able to enter the complete 4 digit code. Just can't understand why any phone would be designed this way. If it's an overly sensitive proximity sensor I could understand that - but this is the second phone I've had with the exact same issue. I now try to not hold the phone to my ear at all but use the speaker function instead.

[Q] Issue with Proximity Sensor?

Hi Guys,
Newbie here, wonderful forum and lots of tech stuff, kudos to every one who have contributed.:good:
Facing couple of issues with my NOKIA X, request your help pls!
Issue: Screen goes blank during a call, when using the phone without headset, & doesnt come back on, untill the call is disconnected by the caller at the other end.During this period, when the screen goes blank, it leaves me with no access to the menu, dialpad, etc and the call disconnect button doesnt end the call as well.
1) Turned off proxmity sensor in the "Phone-Settings" menu, it works properly.ie the screen stays "on" during the call and no issues with disconnecting the call, accessing the other dialpad options etc.
2)Also Turned on/off Automatically adjust screen brightness , observed that issue is intermittent.
Any leads would be helpful.Not sure about sensor calibration and tweaks
thanks

the screen supposedly to turn off during calls when it detect something near the proximity sensor ie your face when attending calls, this is to preserve power, and it should've come back on again when u bring it far from your face. this is default bahaviour on all smartphones nowadays.
but when it doesn't come back on again after u bring it far from your face after making calls, then thats a problem.
u use screen protector? a thick one and it covering the proximity sensor perhaps? from my experience thick screen protector that covering the sensor can interfere with its sensitivity.
the sensor is on the right side of the nokia logo infront of the phone. look closely and u could see it.

Thank you mdfzhi, i took off the screen guard (yeah it looked unusually thick :silly and it seems to work at the moment, will monitor and see if the issue pops up!:good:
thanks again!!
search for screen protector that doesn't cover the proximity sensor, or if u cant find one that doesn't, cut yourself a hole in place of the sensor.
i'm using a thick anti fingerprint screen protector myself but its not covering the proximity sensor.
