Hello friends,
My situation:
Out of the blue my phone stopped responding to the wake-up action. Every time I lock it, I have to restart for the screen to turn on again. The power button is working just fine, since I can go to recovery mode and use it to select options there. I even installed a somewhat wrong version of the TWRP recovery that would not boot to the main OS, but the power/lock button would work just fine in recovery, putting the phone to sleep and waking it up. I reverted the instalation after so I could boot to the main OS ( Android 10). I tried reinstalling(from an official image of the rom) the full rom, incluing everything from OS to Bootloader, and could not make the wakeup action work again. Once my phone is on, if I lock it, I have to force a restart to turn the screen on again. I even tried sending a direct command to the OS using adb shell input keyevent KEYCODE_POWER and KEYCODE_WAKEUP to no success. Even tough I made sure other common events like opening the camera (KEYCODE_CAMERA) were working when the screen was on, and I bet it was working when the screen was off too, but it would not wakeup the screen and I would not be able to see the camera view finder.
My phone is a Samsung galaxy A30, model SM-A305G, currently in Android 10.
I think I described the problem good enough, but If anyone have a problem understanding it, just let me know and I try to explain it better.
Can anyone help me out here? I tried a lot of things to not success.
Thanks!
I have the exact problem you described, did you find any solution ?

flash official ROM with Odin or with twrp
I tried several different official roms by odin but nothing changed.
Power button and volume rockers works perfectly in recovery or download mode but in the OS volume rockers do not do anything (nor volume button commands from adb shell) and if I press the power button phone sleeps and never wakes up.
Very very strange at this stage I disabled sleep and with a amoled black bacground using the phone but I really wonder wtf is going on ?

very strange
I made furher research about the issue and here is what i've found.
Some videos mentioned same problem in similar samsung models and they stated that changing the daughterboard that connected to motherboard via screen flex resolved the issue. Other videos reflowed the connector in the motherboard side of the flex.
Also phone not responding the adb power commands while in sleep but responding fine when awake got me thinking there is a problem with a some kind of awake pin of screen. Probably there is a short or a missconnection in that pin. That's why solutions in the videos work I think.
It is definitelty not a software issue because it happens in every official or custom rom except in twrp (which does not put screen into sleep mode according "mScreenState" info)
It is not a hardware issue related to power button. Power button works perfectly fine in recovery, download mode and when awake.
Its a hardware issue that probably about the connection that sends wake up signal which maybe from motherboard side of the connection or maybe daughterboard side.
Not a real solution but I found a app called touch protector which has an option that you can disable the touch and set screen brightness to 0%, basically means normal off state for the amoled screens.
I set double click of volume down to sleep mode for touch protector. Maybe with some keymap editing someone can set powerbuttons function to not real sleep but touch protector's sleep. This will be best software solution.
In the hardware side if the problem is daughterboard it can be swapped easily but reflowing smd connecters in motherboard could be risky for me and I don't want to open the never opened device for not solving the problem.

Hello,
I was wondering if there is some way to track what is happening on my phone? Since my screen stops working when waked up from standby. i.e. if i press the button at the top to standby and then when i press it again and reach the lock screen the touchscreen is not working, it is simply not registering touch and neither are the 4 small buttons on the bottom (back, settings, home, search). However, the OS in itself is still running as I think since I can still see the time move and if I hold the off button the menu comes up for reboot etc.
Anyone heard of anything like this or any tips how to solve this? I am rooted and running CM6 I think at the moment.
Thank you,
Svarto

so the only way to escape this is by pulling the battery and rebooting? when you do reboot and dont go in standby, the touchscreen works fine?
You can check the issue using logcat and /proc/kmsg.
Also, you can read my threads on the subject, describing the same error with logs, and see if your logs are the same.
I'm currently trying to check if the error repeats itself after full wipe and starting from scratch. In the meantime it didn't show up until I applied a theme, and then after reflashing the ROM it's gone again - I'm still checking, only a day has passed.
Yes, the only solution is to pull out the battery and reboot. Then it works fine and I can go in and out of standby. I havent found a particular pattern to it happening so it is hard to reproduce.
I will have a look at that logcat and your other thread!
Just to guide you - when it happens to me, the phone gets stuck with mmc0 access that receives "CRC error" reply and doesn't go through. Pressing power button for a long time several times and playing with trackball / touching the screen between presses "releases" the "lock", and you'll be able to work with the phone again until you put it to sleep again. If you turn WiFi and BT off and then back on - the problem seems to disappear.
My Fiancee's G1 wont turn on at all,No T-mobile slpash screen or nothing.LED lights turn on and Call,Home,Back and Power buttons light up except for the screen itself her phone wasnt rooted,I have never experienced this before.
Can someone please help?
the phone is not turning on via the power(end) button???
try pressing the camera button and keeping it pressed, also press the power button to enter into hboot mode...if u succeed in entering that mode, the phone is fine, or else it could be bricked.
Try Home+Power see if you can get into recovery mode.
If you can wipe cache data.
Hi everyone, hope it's okay to post this here since this Question relates to mine.
I'm having a trouble like this except instead it's like my backlight went out, it was working fine until my alarm on my phone went off and when I went to turn it off I had to take the battery out of my phone because the screen wasn't pulling up. It flashed basically, so when I put the battery in the screen came on but no backlight. Could it be due to Cyanogen? I'm restoring my backup to see what else could I try?
could u be a bit more specific?phone is working??? calls etc???or are u stuck somewhere????
As I said, the screen came on but no backlight. The phone works fine except for the backlight I'm trying to figure out if it's a hardware issue or a software issue. I don't know how much more specific I can get really except that the only way to see the screen is to hold it at a certain angle so the light hits it just right.
If your phone's power button is in a 'pressed' state, like mine, (turns on automatically when battery is inserted), it is a hardware issue.
Here is a hassle free alternative to turn on the phone when it is in sleep mode, without relying on the power key!! Takes a minute or two only!!
1. Get 'Go launcher' from the app market (play)
2. Get 'Go Locker'
3. Now Enable Go Locker on your device. And you are done!!
When the screen goes black again, Just press the volume button, The screen wakes up!!
Using this method you don't lose the normal functionality of the volume rocker!!
I recalled that I used to have Go Locker on my phone, and that when I pressed the Volume key the screen turned on!!
At that time I found it a little annoying, But now it has turned out to be such a gift!!
* For this method to work, your phone has to be rooted.
The power button is not going to work until the hardware is repaired, I prefer to use this method, because it is a safe and quick method!!
Believe me I looked around the internet and this forum for a fix, The usual method: editing the system files on the phone, and after which the volume button cannot be used to control the volume.
For those looking for a quick fix, just follow my method!
Cheers!
There are also several roms out there that have the volume rocker wake built into the rom without making it completely useless for it intended purpose. As well as several that offer a go to sleep toggle in the notification window so you can lock your phone again.
so this is a hardware issue ? i had been using the go locker i been using but the power button is annoying cus it keep showing the power button options . and killing my battery.
only fix is samsung?
Pretty much every version of cm for cappy has volume rocker wake as an option, because of this common problem. I use app called turn off screen as well.

I had the exact same problem with my Epic Touch 4G. Thought it was the ROM, the overclock, etc. I flashed back to (almost) stock, went back to original clock speeds. I couldn't figure out what it the world was causing the issue, until it got worse. Then, I noticed that even brushing past the power button would wake the screen, and about 10 seconds later the phone would reboot.
Long story short, I bought a replacement power switch, soldered it in place, and have had zero problems since!
Several eBay sellers offer the proper replacement switch you'll need.
(They don't include the required skills to properly desolder/solder it, however. It's a tiny switch - about 4mm x 2mm x 1.5mm, and you'll need a good quality fine-tipped soldering iron.)
Hi everyone I've got a big problem with my wife's Mi 5. After some minutes/hours of usage the touchscreen stops working and the only solution the make it work again is to reboot the phone (by keeping the power off button pressed).
I've tried some rom (MIUI stable, MIUI dev, Paranoid Android 7.3.0) but all of them have the same problem, someone has got the same issue?
I think it's not only an hardware problem because the touchscreen works most of the time... Any ideas?
I'm having the exact same problem with my wife's Mi5 too. I thought she was talking rubbish until I started using the phone full time over the past few weeks.
Symptoms:
Screen switches on and accepts one touch event.
Screen is then unresponsive to touch events.
All other buttons (home, power, volume) all work OK.
All functions work OK (calling, SMS, etc) via remote control (MyPhoneExplorer)
Screen then becomes responsive again after reboot
Tried so far:
Clearing dalvik/cache
Clean flash - using MiFlash and China dev ROM
Opened phone, cleaned all ZIF connections and reconnected.
It almost feels like something in the touch firmware or driver crashes and does not reconnect - as the phone is clearly usable save for the touch panel.
I'm going to ask Bruno/bgcngm and see if there's anything I can do to try and diagnose the issue.

In my case unresponsive screen to touch events, all phisical button works and the only option to make it works again is to reboot. I didn't try to use it with some "remote" control.

I didn't try to open the phone, but I installed all roms with TWRP and format data/wipe cache/dalvik before.

Well on my old mi4c i had similar problem. I mean sometimes when i pressed power button and tried to unlock it screen didn't work. For me solution was simply to press power button again to turn off screen and then turn IT on. Maybe this will help u. Have u try that ?

Do you think it's something related with Doze or standby? I think so because today (and yesterday and so on...) I wasn't able to turn off the wake up alarm (the phone was in standby with the screen off all night) with "the screen" but I have to force restart the phone with the button... and it's very annoying.
Maybe we can try with some Marshmallow ROM instead Nougat one.

I'm facing same issue.I've changed my display panels but it doesn't solve my problem.it is quite painfull.i don't know what should i do.
any update sir?
My MI 5 has a different issue. There is no response if I place the phone on the table, but it is fine if I held it. It seems the touch panel is only responsive when the sort of sensors that a human is holding the phone. I have no idea why it starts to happen in these weeks. This symptom happens even in TWRP, so I don't think it is related some particular ROM. Tried firmware 7.7.6 ~ 7.9.22 with no luck.
skip lock screen
Hi
I know I am late to the party, but just faced the same issue yesterday. To bypass the issue, follow the following steps
1. Restart your phone .
2. Enable developer options from about section in settings. (google enable developer options for specifics)
3. In developer options, there is an option to skip screen lock. Enable that.
4. Voila!!
Hope it will help other mi5 users..
Hi,
I had the same problem. I found this video and I tried to fix it. It worked pretty well. Bye
In a situation that I can't do any service for my Mi5 as of now - is this really loose cable thing ?
Can more folks confirm that this cable solution from above video works ?
exactly same symtoms :
Random screen freeze - only option is to reboot phone or phone goes rebooting randomly itself.
Hi,
My note 8's screen got damaged a month ago, but
from past two days the power button seems to be
unresponsive.
I have to press it atleast 10-15 times for my screen
to wake up.
Even if the screen doesnt turn on by a single click,
the usual touchscreen functions still work.
Ex: I can still open the particular app by clicking the screen
on the specific area.
Kindly help.

There's nothing any of us can do to help you when it's a hardware issue like this. You need to open the back of the phone using a heat gun to loosen the glue and then take the power button out and replace it with a new one.. There's nothing else that can be done and I would suggest that you not shut the phone down or let the battery die out because then you may not be able to turn it back on until you get the power button taken care of!

Hi MrMike2182,
Thanks but let me elaborate the issue.
The power button seems to be working fine because it takes approximately 10 to 15 clicks to turn on the screen (sometimes 1 or 2 click)
Let's say that I click the power button and the screen doesn't turn on, the screen functions work fine despite showing black screen.
Ex:
1. If I click on screen location where samsung music is placed and open it, and if I and click on the location of the play button, it plays the music just fine.
2. If I click on the restart button when the screen is black (not turned on), the phone does restart. The Samsung logo lits up just fine. (Mensing to say, the bootup process is not affected)
Also, note that if I successfully manage to turn on the screen after clicking the power button 10-15 times and if I put it to sleep again. I can easily turn on if I click the power button immediately (within the span of 2 seconds).
The problem persists only if the phone is kept I'd for 5 to 10 minutes.

Ok based on what you said now I don't believe there's anything wrong with your power button and when you press it and the screen doesn't turn on, in reality it actually is on and it's possibly damaged which is why you can still use the screen functions with the black screen. Whatever type of damage you say happened to it could be causing the backlight to not work but the screens touch function is fine.. Try rebooting into recovery mode and select to clear the phone's cache only and see if it helped anything.. If it doesn't help anything it's pretty much a screen hardware problem and you'll still have to get into the phone's internals..

Since the factory reset didn't work, then unfortunately it really is a hardware issue.. I think you need a new screen..
I have the official led cover case, just opening the case will turn the screen on... Just a temp fix until you can get it repaired maybe.
