[Q] Screen flashes after Samsung logo, screen black, vibrates every 2 seconds - T-Mobile Samsung Galaxy S II SGH-T989

My phone just started acting up really weird. Whenever I would graze the power button (not even when I push it in all the way) the screen would lock and sometimes immediately turn back on. Some times the power menu would come up. Other times it would just restart and go into this weird loop where the screen would be black, the phone vibrates, and the LED just flashes. Does anyone know what I should do about this? I was using CM9, but this happened pretty randomly so I don't think its a software issue.

Try flashing a different ROM. There may a bug or something on that ROM that could be doing that.

You just got a malfunction power button. It happens a lot. You need to call samsung/tmobile for warranty service.

[Q] Help!! Evo screen won't turn off

I have strange behavior with my EVO as of late. The screen will no longer turn off when I hit the power button or when it is supposed to time out. The bottom buttons are always lit up and when I hit the power button the screen blinks off and then the lock screen comes up. The same thing happens when the screen is supposed to time out. It blinks and then the lockscreen comes up. This happens when it is plugged in and unplugged. I've tried using multiple ROMs and it does it with all of them. It just started 4 days ago after I got a text. Anyone have any ideas on how to fix this?
Current Running OMJ Gingerbread
I would start by first backing up all of my data and then re-flashing the rom with a full wipe.

[Q] NO WAY! This is not possible?

I was talking on the phone and BOOM it resets.
It started reloading and can't! WTF!? It just gets caught. The Samsung logo comes up and then the darkside boot animation (been running this rom for a few weeks). Then it blacks out and does these intermittent vibrations like it's trying to boot but just stays black.
When I take out the battery and put it back in, it attempts to load itself without me touching any buttons. After the boot animation it goes black and does a single vibration that pulses every other second.
I've changed the battery several times, plugged in, unplugged, everything I try can't stop this.
I attempted to get it into recovery. After I get it there, it resets within seconds and puts me back to the same place. There is no way to get into download mode as it goes into this weird loop as soon as I plug the phone into USB.
Ever heard of this? What do I do?
Your explanation sounds like a hardware issue. your power button is being pressed and held without you doing it.
1- is the phone in a case? take the case off.
2 - if no case, did you get the phone wet? somehow the power button connection is being activated.
3 - power button is stuck.
Possible solution - remove battery then press and release the power button several times.
Let me know if that solved the issue.

[Q] My One X sometimes has trouble "waking up", has anyone else had this?

I have recently encountered a problem with my hox, where, if I press the power button, the screen doesn't awake. It's a little weird, because the back home app switcher buttons do light up if it is dark enough around me and, after pushing them a few times, the volume buttons respond as well.
I haven't fully tested it, but it seems like when I wait like a minute or so, maybe more, the screen does finally wake up. I have also held the power button several times to restart it while it was like this and then the screen doesn't light up until the sim unlock screen pops up.
I have yet to factory reset the phone etc., but I was wondering if anyone else had run into this problem. I have looked around the internet, but was unsure what to search for.

Are u using sweep to wake?, that sometimes causes this problem

Nope, I do not have sweep to wake.
Well, after a while of being okay, the issue is showing up again. If I press the power button it does wake the phone somehow (back, home, tasks lights light up, volume can be altered), but the screen wont come on. And when it's one of those rare moments that it does turn on the UI flies everywhere, making it literary uncontrolable, until at some point the screen just turns itself off.
I am not running any custom things, everything is stock. I tried a factory reset without erasing the SD storage. I also have just sent an email to HTC, but it being weekend and all I still have to wait a day or two.
Any other things I could try?
Never had this problem with the HOX.

Hi, I was wondering what did you do regarding the lockscreen problem. I'm having exactly the same problem here. I've already done a factory reset but it did not solve the issue. From time to time I'm not able to unlock the phone.
Please HELP!!!
It sometimes happens to me, recently after clearing the clock and weather apps and widgets. I don't know what it is.

G3 VS985 difficult to turn on, recovery mode buttons don't work

My VS985 has 2 problems, which may be related to each other. The first is that, when the phone is fully turned off, turning it back on again is difficult. When I press the power button, the phone just vibrates at me and then refuses to turn on. Screen doesn't light up or anything. Pressing the power button again does nothing at that point. What I have to do, sometimes up to 7-8 times before it turns on, is remove the battery, wait a few seconds, put it back in, then press the power button again. It'll vibrate every time, and eventually one of those times it will turn on and boot up.
The second issue is that I've found it impossible to get into recovery mode using the buttons. I can get in just fine using the quick boot app, but that's not much use if I ever end up in a state where I can't boot into the OS. Apparently it's supposed to work by turning the phone off, then pressing and holding the power + volume down buttons and waiting for the LG logo to show up. I've tried this many times, it never works, possibly because of the first problem.
I bought this phone used, immediately used ODIN to downgrade it to the original stock OS, then towel rooted it and installed CM (LOS 14.1 now), so I've no idea if this phone has always had this problem or if I caused it. It's not a big deal since I always keep my phone on but makes trying new ROMs scary. Has anyone heard of this before, or have any idea how to fix it?

Black Screen on some Reboots...

I am wondering if anyone has experienced the same issue that happens to my phone every few weeks. I don't usually reboot my phone, but sometimes I do. Occasionally, when the phone starts, the screen is completely black. If I shine a flashlight on it, I can sometimes faintly see the screen. The only thing that can resolve it is holding down the power button for 10 seconds so it restarts.
Sometimes when it happens, if I'm in the car etc, I can't tell if the phone is on or off, so it's a bit of a headache.
I've completely reset my phone and flashed an Android 10 Image a few months ago, but it still occurs. ( This was a full factory reset with clearing cache etc in recovery ). I've never rooted the phone, but have always had bootloader unlocked.
Anyone else ever experience this?

I'm still on Android 9 and occasionally this happens to me too. I rarely reboot so I don't notice it that much but it does happen. If I hold the power button down I can feel the vibrate feedback for the power menu presumably. I've never tried to troubleshoot it investigate because it happens too infrequently for me
