And those buttons are working normally when you turn on your phone (and the screen is on, too)? Can you go to home with home button or lock the device with power buttton?
Maybe just a hardware issue?

buttons
when i power on phone i can use every button normally until i block it :/

This sounds like really random issue, may be a hardware one. If reflashing stock rom trough odin didn't help, then you probably should give your phone to service

Black Screen

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.

I don't know what ROM you're running, but MIUI has the option to do what you're asking. It's in the settings menu (I believe under Lockscreen).
oh, ROM CM7 have it also, but I want separate app. Do you know any apps ?
Widget locker. Like 3 bucks in market enable easy wake
Sent from my Samsung Galaxy S Captivate with ICS and a broken power button.
i just ran into the same problem. golocker is working great for me. and its free in the market.
Also MiLocker.
Fix Broken Power Button by Destil
I found this..
market.android.com/details?id=cz.destil.fixbrokenpb&hl=en
When I tried to download it said it wasn't compatible with captivate but I found the .apk and it ended up working. I attached the .apk I was using to this post.
Another thought, I took my phone apart and cleaned it. I took everything apart down to the motherboard and I poured a little rubbing alcohol on the actual button and pressed it a bunch of times (no battery in of course) and after it dried out it seemed to help get it working again.
Also, when I started having problems again I installed a different kernel and that seemed to help as well. Who knows.. but it has been working ever since.
The Fix Broken Power Button by Destil .apk is below
Thank you topiratiko, I was about to go crazy worrying about not being unable to turn my screen on. But what will I do if the phone shuts off? How will I turn it on? My power button seems to be unable to work.

You can allways go into download mode and flash a kernel for ex and check reboot so it'll boot up, or even better use a jig by inserting it for just a bit to power on and to avoid download mode.

[Q] Lockscreen problem

Hello @all,
much times, when i active the mobile by pressing the power button or home button, it shows the lockscreen, but when I press the button to unlock (e.g. ics) it wont recognize my finger. I can press on the whole screen. It seems like the screen does not detect my finger. when i switch of and then switch on the phone again ( just screen of / on ) it may work, but sometimes i have to repeat this procedure. Im getting quite angry with my SGS as I can not unlock it how i want.
Anybody ideas. This problem also appeared with miui...
kind regards

If youre using an older version of ics builds it was a common problem but upgrading to latest it will disapear. If youre using other rom, i don't know but on those based on GB i never encounter that problem.
When you are on ICS try flashing another kernel (like derTeufel or semaphore). This solved the problem for me.

(Q) Screen stops responding?

So across all roms including stock and cm based my touch screen will randomly stop working and i am forced to reboot the phone via the little pin hole method unless i am missing a hardware key reset combo? Anyway the screen turns on and everything looks like it works except the fact that none of my touches register at all? How do i fix this issue? Its not a big deal when i am at home with a pin or pencil but sometimes i am away from home and cant reset it...

Well, just hold down on/off button and power up button for few seconds. You will feel a vibration. It will restart
Hold it a bit more and it will switch off with three vibrations.
I guess you should get your phone checked. It seems to me hardware problem. it could be a bug too but chances are slim!
Secondly, try clearing dalvik and cache but I am afraid it wouldnt be of help!

Just go on stock rom n relock your bootloader. Sony might ask and make sure you say nothing about rooting, custom rom or anything. Just it's not working well should be the answer.
Secondly, try volume down +power for few seconds when phone is on. Even try volume up+down +power for few seconds.
Make sure you hold these buttons simultaneously.

Samsung Galaxy A30( SM-A305G ) does not wake up. Any suggentions?

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.
