Screen won't come back on after call. - EVO 4G Q&A, Help & Troubleshooting

The EVO my wife has, the screen will not come back on when she is wanting to end a call. No button pushing will wake the phone. She has to plug her charger in to get the screen to come back on so she can hang up. She is completely stock. Any ideas?

Have her download and install a different dialer and see if that works. Just search 'Dialer' in play store and pick one that has good reviews.

Have her clear the phone cache and data. Did she install anything recently?

I will have her try both suggestions and see what happens. She hasn't downloaded new. Thanks for the info.

Proxy sensor I think its on the left of the ear piece just wipe it and turn your phone flat screen towards the floor and flip it back up or just wipe it lol

Wierd launcher popping up when I hit home

Can someone please tell me what this is.... I haven't installed any launchers or anything
Sent from my SPH-D710 using xda premium
Task manager doesn't show anything. And hitting home doesn't bring up twlauncher
Sent from my SPH-D710 using xda premium
That is not a launcher that is clock mode. It can accidently be triggered if you have dust in the USB slot, or if your phone has had some water damage. Hitting home should get rid of it....
i believe that is the clock app, your running ics rom ?
Thanks I'll clear out the usb with some dust off... And no ics

If my post helped, I'd appreciate you hitting the thanks button
***** The real solution*****
It is in doc mode.Reset the phone by taking out the battery all will return to normal.
You can thank me.
If those don't work try wiping your ram with the task manager then pressing home or forcing another launcher on to your phone through Google play site on your comp

Phone vibrates and won't boot

So I was listening to music on my phone with slim bean and it fell behind the bed and when I found it all it does is say Samsung and vibrate in a consistent pattern. Also if I remove the battery and put it back in it vibrates as soon as battery/charger is connected. Does this mean it somehow got in bootloader mode? If so is their a way to get it out without my PC? I tried getting into twrp but. No avail.

No problem. I knew there was something on it but didn't know the details. People have also had a similar problem with Pandora. Don't know if that's what you were listening to, but there seems there's a problem with Pandora and the latest roms.

I was listening to music from my SD card. I got it to boot
But I didn't have the similar in and when I rebooted it it did the same thing. Also got it to load the tarp splash and it rebooted then and I can see the screen flicker like it was booting and the power button was pressed. Looks like I'm going to have to send it off. Hope I can get it replaced for free if not I'm gonna look at a different phone.

Screen Goes Dark During Call

Has anyone ran into issue where you make a call screen goes dark like it's supposed to however if you want to end call screen won't come back on until call ends on the other side. So if person doesn't answer I have to wait till voice mail picks up and hangs up on me after it times out.

Phone isn't rooted. I have tried to hit all the buttons including power to turn it back on after it dims out and still nothing. I'm thinking of doing business factory reset but I rather avoid it if I could.

Got a screen protect covering the proximity sensor? Yours might be too sensitive. I had the same problem with my n4. Solution was no protector or wait till dearth or whatever brand you use to not cover the sensor. That was the first and only phone I ever had that issue though.

Did reset still same issue. I'll try without case, however I have had no issues with case till now.

Also heard of this bug in a German Android forum: there have been some users reporting the same problem without screen protector or case. Still don't know why this happened but You're not the only one with this bug

Yesterday I wanted to read a numberplate from a picture to the person I was talking to. Had to text it to him later because the screen wouldn't turn on.

Enter *#0*# in the keypad to open the "test menu".
Press the Sensor tile and test your proximity sensor's function bij moving a finger over it.
If it does not change value from 0 to 1 and make the screen go green, your proximity sensor is likely to be broken.
Replacing the front camera (which houses the proximity senor) will then fix your problem.

I went into store today to speak to a tech that used to work with when I was a sales rep @ sprint. He told he has seen issue a couple of times. He says when that happens its a sensor issue. More common with fones that where 1st shipped out. He could of replaced it if I wanted but he wanted to avoid giving me a refurb. He did a couple of tests and it's been working since. He suggested if it happens again to bring it back again.

I admit this is sometimes frustrating for me too. I'm curious as to a quick fix.

phone goes completely black and locks up after calls - help

i've never seen anything like this in all my years now with android. no matter what rom i am on comletely stock or any of the custom roms when i make a phone call my phone call and the person doesn't answer my phone is black and locked up. i can't hit the power button to turn it on the only way to get my phone back is a battery pull.
basically, when i make a call i cannnot turn the screen on to hit the keypad, can't do anything. if i make a call and the person answers everything will be ok - after they hangup. i can't hangup since i can't get to my onscreen buttons to hangup.
things i've tried
stock and custom roms with no apps loaded
wiping multiple times
fixing permissions
dialer one from the market
any ideas what could be wrong? it must be a hardware problem or something.
Is your proximity sensor working correctly? Try using some of the motions in settings.
Sent from my SPH-L900 using Tapatalk 2
yeah, i was thinking the proximity sensor must be broken. but even if it is broken why would i not be able to hit power to turn the phone screen back on.
ive never used motions before not sure i'm doing it correctly to determine if its broke for sure

I think what he's saying is go into settings>motions and check quick glance. Then with ur screen off wave ur hand over ur prox sensor and ur screen should turn on with info about ur phone and current time and such..

yep, i'd say the proximity sensor is broken. doing this in the motion settings works fine on my brothers note 2 and will not work with mine
any idea what my options are if the prox sensor is indeed broken? i suposse the only option is to try to take it back to sprint.

Proximity sensor and phonecalls.

Why when I press dial the screen turns off right away? The screen should only turn off when I put it next to my ear. It's very annoying when I'm dialing automated systems and need to use the keypad because if I manually turn the screen back on and then put it next to my ear to talk the screen doesn't turn off and I end up accidentally pushing buttons.
On an iphone the screen remains on and only turns of when put next to my ear, and turns right back on when pulled away from an ear. Is there a way to duplicate this behavior on GS4?
Go to settings/My device/call settings and select turn off screen during calls. That should do it.

Thanks, the screen doesn't turn off anymore but it also stays on when I put it next to my ear... I don't get why Samsung can't get a basic function like that right.

In your original post you forgot to let us know what exact rom you are using.
It would be very helpful to know that and other specifics before offering any suggestions.
Good luck!
Well, I tried this on a stock rom with the same result. Are you saying it works for you?

Download an app from the android market (its free) called AndroSensor and see if that app is saying the proximity sensor is blocked. You might have a spec of dirt causing it to always return that its blocked. Read other threads with same issue, and in the one thread, the guy at T-Mobile took a can of compressed air and blasted out the earpiece and it fixed it.
I downloaded the app and proximity sensor does not show any reading all the other functions have a graph next to them but not the sensor. Does this mean it's broken? And if it is broken does tmobile exchange the phone or do I have to send it back to Samsung?

It's definitely a hardware issue which should be covered. You just gotta make sure you get it back to stock and reset your counter with triangle away.

Agreed. Definitely hardware. Your sensor is reporting that the sensor is never covered and always open. Use that app and a test call to show the Rep at T-Mobile.
