PLEASE HELP :( Screen during phone call issue - Droid Incredible Q&A, Help & Troubleshooting

I screwed up.
I was installing yet another new screen on my phone, and I must have damaged the sensor that dims and brightens your phone. Somehow.
The problem is everything on the phone works, except when I make a phone call. Then the screen turns off and will not turn back on unless I take the battery out. This makes me think the sensor still thinks the phone is held up to my head. None of the buttons work, no matter how much I press them or no matter how long I wait to press them.
I don't know what to replace, otherwise I could likely solve the problem on my own, but I think this issue could be solved on the software side fairly simple.
Could anyone recommend an App (or maybe a ROM.. but that limits me) that disables that stupid head detection? I can not find it in settings either.

I had a similar problem to this once but it was related to a kernel. When id take the phone away from my head the screen would stay off and not come back on until i would swipe my finger back and forth over the proximity sensor a couple times. The dev of the kernel Tiny figured out the issue and fixed it in his next release. Kind of sounds software related but hard to tell. If it does need replacing its called the "CM3602 Proximity sensor - 0.5mA by Capella Microsystems". I believe this part acts as both the proximity and light sensor. Does your screen still dim and brighten when set on auto brightness? There is an app on the market called "Proximity screen off" but i cant figure out how to get it to work, mabey you can.

I actually found a simple way to dissable it. Add the line below anywhere in your build.prop
Code:
gsm.proximity.enable=false
I verified that it does work.

I have resorted to that very same app and I can't figure out what to do with it either.
And when I make a phone call, the phone simply stays off ... forever. I can still hear voice mail and all that stuff. I need to take out the battery and power the phone back up after ANY call...
I am pretty sure I know what I did to break it, but I rather fix it software wise if someone could explain what to do. I'll fiddle with that app a little more.

Did you see my post right before your last post. You can dissable the sensor with a build.prop edit.
Use a file explorer to go to /system/build.prop and use a text editor to add the line from my post above.

I did that, it didn't work. Can it be at the very bottom of the build.prop?
edit: Tried again, it just simply disables all the buttons.
I had this issue once before and it was because I had the sensor covered with a piece of double sided tape. But this time I fear I just straight up damaged the sensor somehow while repairing the screen.
What works:
EVERYTHING!
What doesn't work:
I dial someone or they dial me and if I answer the phone, meaning I enter into a phone call, the screen goes dark and every button is disabled.
Let me try everyone now while I have it in this mode:
1. Power button
2. Volume up and down
3. home
4. menu
5. back
6. search
7. trackball
Only way to get back into home screen is to take out the battery.
Ugh, I wish I had just been more careful. If I can't fix this with software I might have to suck it up and live with this giant pain in the ass until my upgrade time

The build.prop edit worked for me, and it didnt dissable any buttons. The edit can be anywhere in the file as long as its on it own line. Did you remember to mount system r/w first, and to save the file after editing? Are you rooted and s-off?

I think so for all that. How do I double check s-off?
Also, I found a way to get the buttons to come back on after I enter a phone call or the phone call ends.
Simply plug the phone into a power charger, because that always wakes my phone up. But other than that I can't find a way and that is useless to me out in the "field".

You can see if your s-off by booting into hboot. Pull the battery reinsert and then hold volume down and power untill a white screen appears. The end of the first line should say either s-off ot s-on.

It says S-off.

Download and flash this thru recovery like you would a rom or mod. http://dinc.does-it.net/dissable_proximity.zip It should dissable it for you. The first boot may take longer than normal as it also clears the cache and dalvik-cache, so be patient.

I figured out how to use that app Proximity Screen Off, but it wont help you in your situation. What it does is allow you to turn on and off the screen by holding your finger over the proximity sensor for a configurable ammount of time. Basicly created to prevent wear on the power button. I kind of like it, especially since i think my power button is wearing out. Despite cleaning it it tends to stick sometimes.

Flashing now, I will update you once it is done <3.

It must be something else. I flashed it and it still refuses to keep the screen on and the only way I can revive it besides taking out the battery is plugging it in to get back to the lock screen....
*sigh*

That sucks. To rule out a software issue i would do a nandroid and then flash a fresh rom and see if that fixes it. If not i would say you need a new sensor.

I might check out the new ICS rom. Maybe by some miracle it will fix the issue.

check if phone is in standby without switching it on by accident

ok, has anyone else noticed this problem,
sometimes i switch my phone off to save battery and it will switch itself on in my pocket so i need to check every now and then to see if it is really off, however, the only way to switch the screen on is with the power button so if my phone was really off then i have to let it start up and switch it off all over again.
i'm going to have a look for a way to remap the buttons without root as i cant get unrevoked to work and i cant be bothered to go about it the long way
hmm im not sure if this is the same issue, but sometimes the keys on my desire are on with the screen being turned off, im not sure if it happens on its own or what, not a big deal really

I noticed this, it is very annoying!
What ROM are you using? I use DeFrost 2.3 and you can bring the phone out of standby by pushing the trackball button. A second push unlocks the phone.
I dont understand this. If the phone is on, a single short press of the power button will light the screen. If it's off, it needs a long press to turn it back on - therefore it's pretty easy to tell the difference

Mine is unmodified and i'm not planning on changing that until HTC stops issuing updates. Sounds like a good feature though, bit of an oversight on the phone that.

Careful, it may burn the LED out if you keep it constantly on.
rofl. this burn stuff is constantly floating aroung and is still crap.
why do you think, they enable the led while charging? because it is likely to burn?
who ever brought that up .......

I agree, I think the only LED to be worried about having on for long periods of time is the SUPER BRIGHT Camera Flash LED. It's obviously a different LED than the charging/notification ones, and snudel makes sense when he says that it's enabled while charging.
snudel, do you have a link for this blue LED app? I don't even think I've ever seen the blue LED on my Desire glow, but it would be neat to have it lit when the phone is "awake".
Cheers!
you can download a blue led app here:

Broken power button

I have a sort of weird issue. I've got a rooted evo4g with an unlocked bootloader running alter rom. I had some issues with it a while back, so I ran fix permissions and cleared the caches through amon-ra. when I did that, all hell broke loose. my power button stopped working and the volume button took over to wake up the screen. Not only does the power button not work when booted anymore, it won't even work in recovery or in the bootloader. the volume buttons will navigate in recovery, but not in bootloader.
I would like to do a nandroid backup so I can reflash my phone and then just restore my texts, call logs, etc on a clean flash...but since I can't select any menu options in recovery I can't do a nandroid backup.
I have cwm touch for my nexus s 4g, but I don't see one for evo 4g....only standard evo. is that one the same? can I still use it on an evo4g? I know some phones are not interchangeable with recovery on variants...like nexus s, for example hs two recoveries...one for 3g, one for 4g.
also, does anyone have any idea what may have caused the buttons to go haywire like this? I've never seen anything like it. I mean, sure buttons die. All moving parts fail at some point...it's in their nature....but switching control to another hw button???? That jusy makes my head hurt to think about how it could have happened!! lol
Download smelkusmod recovery. It has touch scrolling and you can scroll, select and Deselect with the haptic buttons.
Your power button issue could be a hardware failure. Possibly one of the connectors came undone rendering the power button useless.

even though death by soap has twice as many posts but the same number of thanks as you, he is right on about this.
smelkus is a great recovery and is, essentially, touch screen. what do you do if your phone turns completely off, and are you a little familar with adb?

hmmm...good question. It's actually my sister's phone. I'm also interested in knowing how she turns it back on...I'll definitely ask her that. when I turned it off I had to pull the battery and I quickly re-inserted it so it would trigger a start-up, but I'm not sure about how she turns it on if it's been off for a while.
...and yes, I'm novice-level with adb. I know adb, fastboot, etc...enough to get by, at least I have a black belt in google-fu, too...so anything I don't understand google teaches me lol
(btw, my thank you's came from the ns4g section. I posted the first working jb rom for my device and everyone clicked thanks for it....I'm no star dev or anything to say the least )
****
I just texted her...she says it always auto boots when the battery is re-inserted as long as it has a charge. it almost sounds like the power button is just stuck in a pressed position...but wouldn't I notice that when android is booted by the power control menu always being displayed (which I can't even get to display if I do press the button)???
****
I just tested with my ns4g by holding down the power button all the way through a reboot, until after the phone FULLY booted....no power menu popped up.
what are the odds the button is just stuck in a pressed position?? anyone want to take bets? I'm gonna take it apart tonight and see if that's what it is unless someone has any other ideas.

just saw this thread. and seeing as how the phone auto-boots when the battery is put in, it does sound like the power button is stuck in the 'down' position. i recently went through a similar thing with the power button, and i opened up the phone and just put the button back in place. does the button acutally LOOK like it's depressed ( ...hehe..sorry, i dont know how else to ask that..) like..is the button not protruding out like it should? if you're down for opening the phone up (which is surprisingly easy if you have the proper little screw-drivers) then it MIGHT be an easy fix. i had never done it before, and it really was easy. you can put that black-belt to use for some easy video tutorials. but, please procede with caution.

I can't say if it looks pressed since it's not currently in front of me...I know exactly what you mean, though. The inner workings of the button get stuck, and the outer rubber piece will be sort of caved in instead of sticking out like it should.
I build gaming computers as a side-hobby. I'm sure a little disassembly won't be too difficult, as long as I'm not removing any of the guts and I can just get to it by opening the case, I should be ok....too much more and I run into issues when things are that tightly packed into a case.
(reading a tear-down tut now )
Awesome! It should be a piece of cake for you, especially with your video game background. Cool. Let me know how it goes.

screen can't turn on without force reset (P600)

I bought my device (P600) a few month ago,
and suddenly (without changing rom/karnel or doing root) i got a big problem -
when i push the button that close the screen(turn off the screen but the device is still on) or if the screen is turned off automaticly, the screen stay off forever. Even pushing the power button doesnt turn on the screen.
The only way to turn the screen on again is to reset the device (by pushing the power button long press).
I almost sure that the problem is a hardware problem even that it's look like a software problem because after i saw the problem i changed the rom and the karnel to other option to check if the rom/the karnel is the problem and the problem didnt solved.
Someone have a clue which element make the problem?
Thanks (and sorry for my bad english)

I'd bet money on it being a backlight issue.
Test it again in a well-lit room with a bright lock screen wallpaper, something with a lot of bright color. Once the screen turns off, wake the device and look carefully to see if you can see anything. You might have to tilt the screen, but you should see a very faint, dark image.

Unfortunately I don't know of any solution other than sending it in for warranty coverage or replacing the screen yourself.
I've seen a couple of other posts on XDA involving the same issue, but never saw a solution. I've even seen this issue a couple of times IRL (not on my device, thankfully) and have not been able to find a solution. The two times I've seen this issue, the backlight level could not be adjusted, either. Whether it was set to automatic or manual brightness, it would never adjust, the backlight was locked at a constant level, until the screen turned off, and then the backlight would NOT come on again until the tablet was restarted. Reflashing stock firmware and doing a factory reset did not help, either. On one of those devices, the backlight DID start working again for a while after a manual wipe of internal storage, but only until the tablet was restarted, and I think that might have been a coincidence, I was not able to replicate that again.
So in short, I'm afraid I don't have a good solution other than hardware repair/replacement via warranty.
this has just happened to mine - will have to send it into repair, but it had CLEAN ROM installed so they might argue re the Knox trigger - really annoyed about this!

So I suppose my phone has the most weird hardware problem ever.

Please don't move my thread to Q&A as I already made a thread there but no one replied.
So what happens is that a touch is randomly registered on the screen of my phone sometimes when I press the power button. This isn't an HTC lockscreen specific bug as I have established it happens with PowerAmp lockscreen as well. I have done a full factory reset and it is still happening.
I don't use lockscreen security so the obvious problem with this is that so many times upon pressing the power button a notification is clicked and immediately opened as a result. This problem can be avoided by using double tap to wake but it's far too easy to activate by mistake so I can't stand it.
Repeatedly pressing the power button will not reproduce this result, it seems to only happen when the power button had not been pressed for a few minutes. But this cannot be a bug related to sleep mode since this happens when playing music as well.
So what I would really like to know is if there is anyone else with this problem? My M9 had been so perfect all this time but this has just ruined the experience. I don't exactly remember when this problem started but I do know it wasn't there from day one.

Seems like a hardware problem. Something presses your digitizer (touch screen).
If u have any screen protector , remove it.
If not, take it to warranty.
Good luck!

HTC doesn't provide warranty in my country so I am outta luck. I don't have a screen protector so I guess I am screwed.
I guess I won't be buying HTC again. I already tolerated the crack on my bezel but it seems every HTC phone has some hardware issues. It's too bad though because I loved HTC software and performance, the M9 had been nothing short of a spectacular phone for me.
It happened to me too when I used a stupid Samsung charger. Try another charger, I don't know why but sometimes the current of power is somehow overflowing the chassis of the phone that the digitizer thinks the difference is actually a touch on the screen.
I want to update this thread. As it turns out it's 100% a software issue. How I figured this out is that when I turn on "double tap to wake" this problem completely disappears even if I still use the power button for unlocking. So basically the bug comes into play when you turn off double tap to wake as it is turned on by default.
So is anyone not using double tap to wake? Are you experiencing this problem? Unfortunately I find double tap to wake extremely annoying as it is so easy to wake up the screen.

That's quite a unique software issue then. At the risk of sounding like an obnoxious tech support guy, I would absolutely backup everything and then just factory reset (or wipe and reflash your custom ROM) when you get the chance and quickly check if the problem is still there.
I've been using double-tap and it has actually been the opposite for me - I find it annoying how hard it is to wake up the screen because you need to hold up the phone vertically before double-tapping, rather than just tapping while it's lying on the table or in your pocket.

I have already done a factory reset to no avail.
That's strange because I can activate double tap to wake from any orientation.

Oh my bad re-read OP and saw you already mentioned it.
Hunh, I stand corrected I guess, since now I'm able to wake from having it flat on the desk. Could have sworn that didn't use to work. But still, I'm not by any means accidentally waking it (if I pick my phone up, it pretty much means I want to use it).
I can't replicate the digitizer anomaly, so not much else I can say other than good luck. Have you tried custom ROMs?

I can't replicate the digitizer anomaly, so not much else I can say other than good luck. Have you tried custom ROMs?

It might take a day or 2 of usage to replicate the problem, it doesn't happen most of the time.
I wake up my screen accidently sometimes when putting it into my pocket after locking it which is hugely annoying as the lockscreen is kinda easy to unlock once it's woken up.
I really can't be bothered with custom ROM as I am done with all of that. I'll just live with double tap to wake.

That's quite a unique software issue then. At the risk of sounding like an obnoxious tech support guy, I would absolutely backup everything and then just factory reset (or wipe and reflash your custom ROM) when you get the chance and quickly check if the problem is still there.
I've been using double-tap and it has actually been the opposite for me - I find it annoying how hard it is to wake up the screen because you need to hold up the phone vertically before double-tapping, rather than just tapping while it's lying on the table or in your pocket.

That's the design. When lying flat, you can wake the phone with a triple-tap.

Power Button worn out? Accidentally starting Camera despite clicking it only once.

EDIT: Fixed it (for now). Copied from my post on site 2.
What's up guys, I'm sorry for the late followup. It turned out, that I was too lazy to send it back. Now, almost a year later, I'd gotten into fixing phones and got the courage to open up the device and see what's up with the power button. It felt like the issue has been a bit less noticeable recently but I checked the replacement parts prices and how to open our phone up.
I think I've fixed the issue by adding one layer of electrical tape over the button-contact. I believe the issue is that the pin a just a little bit too short to reliably properly click the button.
Short tutorial:
Turn the device off and remove the simcard bracket.
It's actually super easy and you don't need to screw or remove anything. Google "Xiaomi MI A2 LITE disassembly screen battery smontaggio" you'll find a video, in the beginning the guy shows how to remove the backcover. I've used a hard, plectrom-looking "opening-pick" at the bottom, then carefully but firmly around the sites. You don't even need to remove the flex cable from the back, just make sure you don't rip it off. Cut off a short bit from the electrical tape, tape it from the battery to the contact, so it doesn't fall off. Close the case again, turn it on and check whether the powerbutton still clicks (doesn't stick) and test the screen lock. Post back if this has worked or if you've tried it.

Does anybody have a similar issue?
I've ordered the device from gearbest to Europe. Everything worked nicely.
However, recently when I hit the power button it sometimes triggers the double click interaction and opens my camera. I've tested a few ways to press it slightly from the side, with more force or less. However it will 1/3 times vibrate and start the camera like I had double clicked it, it's more likely when I hit it a bit too lightly though. Could it already be worn out after 2 months? This never happened when the device was new as far as I ran remember.
Yes I'm aware that I could change the camera shortcut but this doesn't stop me from worrying about whether my powerbutton will give out soon.
I was using the phone happily in the case Xiaomi has provided. Dropped the phone once and got a little scratch on the VOL Button but other than that, nothing crazy has happened. Does anyone have a clue whether they will still replace it? I'd gotten it in mid-August.

Buttons are usually the main gate to "planned obsolescence". I bought this device after my nexus 5 power button started working funny (I physically removed it and worked only with gestures). So, now I try not to press the button unless necessary. I unlock with fingerprint, and lock with Greenify.
In other words. Make sure of it, if the button starts working funny, I'd file a warranty claim. Or it won't last long and warranty will expire eventually. It can happen with this device and with any other piece of tech.
My opinion.
If you do place a warranty claim, let us know how xiaomi's customer service works in Europe.

when you dropped it
the power button may have got stuck
this is possible and I've seen it on some other devices
you can open it yourself if you don't care for warranty like i do
but the safest option is to claim warranty and yes they would replace it

I have the exact same issue. It started when I installed the Oreo update, but it could be a coincidence. I'm still looking for a fix.
It also happens to me, and I didn't drop the phone... Is there a way to change the shortcut to, maybe, press the power button 3 times instead of 2?

It happens to me too, I disabled the shortcut and just not using it right now. I don't think there is a way to change the shortcut
It happens to me....
It happened for me as well.
And i think it's a software bug, not hardware..

Same here, never crashed on the floor, it's software issue

It obviously is not a software issue. This means that they've used cheap contact points on the button if this happens to many of us. This is a hardware issue.

I'm having this issue since day one. It is obviously software, otherwise the same contact problem would occur when turning the screen ON, but it never happens. Solution is to disable the feature under System -> Gestures -> Jump to camera.
i also dissabled the camera gesture because of this issue.
im sure this is reasoned by a more or less loose power button and not an software issue

How can that be a software issue? Same issue happens to me whenever I use the power button, either to lock the screen or unlock the screen. Also if it was a software issue, it could be fixed via installing a GSI. That doesn't fix it either.

Let me break it down and you can tell me if I'm missing something.
1. Many users are reporting that the camera app starts when pushing the power button to turn the screen off.
2. They are not reporting any other issue with the power button, like the camera app starting when they try to turn the screen on, the button being irresponsive, or the camera app NOT starting when they deliberately push the button twice.
3. The problem reportedly goes away if the double-push gesture is turned off in settings.
Do you still think this is a hardware issue?

When I disable double press gesture from Gestures, still when I sometimes hit the power button, the phone locks and closes the screen and then turns the screen on again which means that it still registers one presses sometimes as double presses. Also if you've ever used a keyboard or a mouse or anything electrical with buttons on it, these appliances do the same sometimes even though you tap one button they sometimes register it twice. Which is a hardware issue. I still can't see any software issue here. When you disable the double press gesture, it doesn't launch the camera anymore but it turns on the screen after locking it (sometimes as usual)

Not for me, so it's possible that these are actually two different problems with this phone. I wouldn't be surprised. :laugh:

Yeah me neither. They don't look like they're going to fix anything or listen to users either. I'm happy with stock Android though.
Hi guys, for me, the problem has fixed disabling the option "Power button lock the phone", and set the option "Lock automatically": immediately.
The fix

I changed the power/volume button assembly outright just the other day, and so far I'm not getting this issue anymore.
I recorded myself doing it here, so you can see how easy (or hard) it is: https://youtu.be/q8kaY-v0q_Q
