[Q] Screen wont turn on after it turns off. ATT Tilt 2

Everytime I boot my phone up, it works fine up until when the screen goes into sleep mode. Once it goes into sleep mode I cannot turn the screen back on, it stays black. The keyboard, end and answer key lights show up when I press the power button but the screen just stays black no matter what button I press.
I end up having to either take the battery out or using the stick to press the reset button on the side in order to get the phone to where I can see the screen again. I have adjusted the settings to where the screen doesnt go into sleep mode and the screen just stays on but that drains my battery. I want to be able to have my screen go off so I can save power but if it goes off it wont come on again until I reboot.
I have done a hard reset. This problem started happening to me when I started using the Energy Rom but I've even flashed different Roms and the problem still exist.
Somebody please tell me what's wrong! I need help! This is a big annoying problem to have. Thanks.

is this problem occurring when you slide the keyboard out?
i had the t-mobile touch pro2 with this problem.
the screen would die when the keyboard was out and not come back.
if this is the case, what i did was...
well. obviously not open the keyboard fully.
but if i accidentally had.
instead of pulling out the battery, i waited...
till the screen 'naturally' went to sleep.
than i would pull out the stylus or press power button
and the screen would come on.

Yes the problem still exist even when I slide the keyboard out. Once the screen goes off, that's it....pressing the power button to get it out of sleep mode, sliding the keyboard, I press all buttons and nothing works. The only thing that "works" to get the screen back on is removing the battery or using the stylus to press the reset button.
When sliding the keyboard out the keys light up but the screen doesn't come on, also pressing the power button lights up the end and answer keys without the screen coming on.

so. whenever the screen goes out, period, you cant get it back?
or the screen goes out and cant get it back once you slide the keyboard out?
if it is only when sliding out the keyboard...
try not opening the keyboard fully on the right side.
on my rhodium, after that point, the screen goes out.

Yes, period. Also, you know when you put your face to the phone during a call and the screen goes off so your face wont press anything on the screen? It doesn't come back on from that either once I end the phone call, it just stays black. I'm assuming you don't have any other suggestions. This Sucks

This has to be a software issue but I don't know where to start. I'm surprised nobody else has encountered this problem. I've grown frustrated of this issue because I don't understand why it's doing this. I have had the phone for almost 6 months only dropping it once 4 months ago and it wasn't a strong damaging drop that would affect anything inside. I guess I'll just have to go last resort and call warranty to swap the phone out. Thanks for the help.

Same problem

My phone also dos not come back on, when I put it in out the sreen with the power button on top, or when the phone goes to sleep. Nothing can put it back on(opening te keyboard, pulling out the stylis, presing the answer-, windows-, back- and end button). I and up using a music players too keep the phone busy what's makes it operational. Cant really remember when this started happening exactly. My phone is at the moment loaded with a standard ROM. I used too have a custom ROM.

My TP2 does this too, although I only encounter the problem sometimes when someone calls. I answer and put the phone next to my ear, the screen goes black as it should and the phone just dies. I can't hear what the other person is saying and the screen wont turn on anymore. I have to take out the battery to reboot.

set light sensor to manual in settings. You have some bad or fragmented code causing the problem. Pretty common actually, many different reasons, but usually either a bad light or proximity sensor or software issue. Setting the sensor to manual should do it, if not, hard reset and allow the phone to fully set up before touching it, to allow full customization process to complete. Search my posts on SOD (sleep of death) for more information.

Funny this was brought up. Now im worried I just dropped 250.00 and have a new one coming.
Mine started with the ear piece quit working. couldnt hear anything except on speaker.
Anyway I started having the screen issue over a month ago, only way to get it back was soft reset with the stylus. Also when the screen was lit, I couldn't hit the power button to turn the screen off. At times the screen would be on 24/7 and I just dealt with it. The times when it decieded to go to sleep was when I needed the soft reset. Well long story short I forgot my charger one day at work and the battery died. after pressing the power button for hours with no response, moving the screen in all diffrent directions as I pressed the button.It came on once after hrs of messing with it. Well today it died again and I am fed up with it so out came the tools. Once I opened it up I noticed the ribbon that feeds the screen from the mother board was worn and torn. the ribbon slides everytime the keyboard is slid out and it rubs on both sides of the phone. I thought maybe mine was just a fluke and was installed wrong considering the phone being 10 months old but now I read this and see maybe its a common problem. The cheapest I could find the Ribbon was 56.00 so I didnt want to chance it not being the issue.

screen freezes when pulling it out of pocket.

hi guys,
got a bit of a problem.
i keep my phone with no case on in my pocket with the screen facing in. when it rings and i pull it out, the screen is not responsive and i have to use the power button to turn it off and on to get the screen to respond by which time ive missed the call. right about now, im missing the hardware button which i was never fond of on the hd2.
it does the same thing when the alarm goes off. wish i could prevent the screen from coming on when in my pocket. the screen is being activated by contact with my thigh through the fabric of my pants pocket and that is somehow messing up the screen and causing the freeze.
phone doesnt feel right in my pocket with the screen facing out.
anybody else experiencing this?
phone is stock.
regards,
asmd.

Same thing for me on occasion. Think your SOL because I haven't found a way around it

Any help for stuck power button?

Have had my phone for months, but suddenly the power button stopped working properly.
It's stuck in a recessed state and has no "click" to it anymore. It's very hard to press, but if I use my nail and push it in the power button does feature, but again no "click" or response to the button press. More than anything I am worried about it becoming permanently broken, likely leaving the phone unusable.
Due to some location/warranty issues, I think getting the phone replaced (for now) is near-impossible/not really feasible.
I am in New Zealand where Google doesn't have any presence and I am unsure if any local "phone repair" shops might even be able to fix it - especially if any replacement parts are needed.
Does anyone have any thoughts or advice to try and fix the button myself? It was in a case since day 1 and I cannot recall any single time a drop would have happened or some dirt/sand/etc. would have gotten in and stuck. I used a "rocket blower" I use for my camera gear to just blow the button area, but no change.
Happy to provide more info if needed... all help is more than greatly appreciated!!!

All I can recommend is a soft key power button...on statusbar or navbar. You need to be rooted.

I use Fingerprint Quick Action app but same deal (root I think). With it I assigned double tap to fingerprint reader to turn off the display.
As for power button replacement, iFixit teardown of the XL doesn't look like an easy DIY thing, with display damage a likely scenario during disassembly. Good luck with that.

It's not a fix but for the moment Nova louncher has great gestures to lock the screen swiping up or down, double tap and more.

I know how this sounds, but try sealing your lips around it and give it a good suck. Like you'll feel that you're sucking air through other gaps in the housing. Popped my button out and it's clicking again. Might only be a temporary fix, but it's been a couple of days without an issue for me. Damn thing has been bugging me for about a month, sometimes getting stuck long enough to hard-reboot the phone. Almost felt like there was some sticky **** under the button.

Phone App Screen Wake Up Issue

Nevermind. Turned out to be my Incipio Tempered Glass Screen Protector.
------
Hoping I'm not the only one with this issue. I can't tell if it's the Oreo 8.1 update or the latest version of the Phone app that's causing this, but when on a call and the screen is switched off, it should usually (obviously) come back on when you take it off of your ear, but in my case it does not. It's basically impossible to hang up (unless the other person hangs up first) or use any feature during the call (keypad, speakers, mute, etc). Pressing the power button does nothing. Scanning the fingerprint scanner does nothing. The only way to get into the phone is through the double power button feature to access the camera.
Needless to say, this is f---- annoying as I like my phone to work like a phone when I'm using it.
I've reset the phone (had to for another issue), and it didn't fix the issue. I forgot to check before the Phone app updated, and I can't downgrade now.
Help.

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.

<message deleted>

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..

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.

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
