[Q] Blank and frozen screen - Galaxy S II Q&A, Help & Troubleshooting

When alarm clock plays I can not turn on the screen. Nothing works. Only if taking out the battery has an effect (thank God ) I had it now for two days in a row and did not have before. I also did not flash anything new in the last two weeks. Am using stock alarm clock and have 2.3.4 running.
What is the problem and solution?

I found the problem. It was the app Green Power locking the screen.

[Q] Unresponsive @ Lock Screen

So yesterday I rooted my phone with glad root, installed tenfar's cwm, and flashed to greyblur 2.1 on my atrix. It worked fine all night, but this morning when my alarm went off I went over, disarmed the alarm successfully then the screen went black. I powered the phone back on it isn't responding to my touch at the lock screen, (when I touch the bottom 4 buttons it still vibrates though) so I can't unlock or use my phone.
Do I have to SBF and start all over? Is this considered a "brick"? Is there any easy fix? Help is greatly appreciated!
ps my notification bar is still working I can see that i have messages, full battery, alarm set etc.etc.

[Q] Clock / Alarm acting weird

Hello,
I've been having some issues with my clock app; more specifically the alarm. I have a daily smart alarm set with repeat for weekdays only.
- first time it FC'd, and that's it. I woke up on my own seeing the FC message.
- second time it didn't even do anything, no error message, no ring.
- today it started the alarm, but my phone was frozen. The screen was black, and I couldn't wake it up anymore, or shut it down. I had to pull the battery.
So I'm just wondering, is it only me or did this happen before? Should I clear alarm data? Install some alarm app? Update firmware?
(Please don't suggest getting an alarm clock, I expect a phone like this to be able to wake me up in the morning)
Currently I'm running a rooted stock KE7.

Alarm doesn't go off

Hi, I'm using the stock alarm and recently it's stopped going off. When I do wake up, I turn on the screen THEN the alarm goes off, what does that mean? I don't use task killers. I do use aeroplane mode while sleeping but that's never caused trouble before.
Only changes that I've made recently was a mod to add boot into recovery etc. but it was an update of a mod I've been using for a long time without trouble.
This mod doesn't add an other alarm apk that can cause a conflict?
Do you see a other "alarm and clock" in your drawer?
Your alarm apk has green or blue indicators?
No, the mod doesn't say it affects the alarm, but I still wondered! I'm not using any other alarms. The alarm goes green when active.
I reset the phone twice and it did not help. I have noticed something: it works if I leave the phone on, if I put the phone in aeroplane mode then the alarm doesn't work. I will re-install the software to see if that helps.
Are you on ICS already?
Issue might be due to the time not in sync when in airplane mode.
Is your time settings set to automatic?
Interesting ideas ^^. Well I did not find out what the problem was, but I restored the ROM to a long time ago and the problem is gone. Yes, I'm on ICS already. I tried deleting all apps and that wasn't it either. I suspect it could have been a bug in a mod.
Hi, so
You turn on alarm
You shut the screen off
You turn on the screen and see the alarm is off?
Try another alarm from the market maybe? If you really want to keep this rom

[Q] Alarm Does Not Ring Sometimes.

Hi,
I have Samsung Galaxy S3:
Android Ver.: 4.1.2
I9300JKEMC1
Recently, the alarm does not ring sometimes. I have no idea why, and it makes a lot of troubles...
I have noticed that when it did not ring, when I click the home botton, I see that the time at the lock screen is incorrect for a millisecond and then it turns to correct.
I tried to turn off the automatic date and time and I use a manual time zone, but the problem keeps showing from time to time ()
Someone have any idea how to solve this issue?
the thusbomb
Anyone???
I tried to flash a new Samsung original rom from sammobile.
I wiped the deivce using CWM.
The alarm keeps not ringing. I don't know what to do...
Again, the same problem; The clock freezes at night and the time it should ring passes.
When I click the Home button after I noticed the alarm did not ring, I see an incorrect time on the lock screen for a half of a second and then it turns to the correct time.
Maybe some application causes this???
How can I find the source of the problem?
PLEASE HELP!!!
You require a service centre .

Moto C - Clock (alarm) app randomly gets stuck and alarm is not triggered

Moto C with stock firmware.
Current status: rooted phone. Yet, the problem has occurred before and after rooting.
The clock and alarm app randomly gets stuck, which provokes that the alarm does not trigger. I attach a screenshot where you can see that the widget has the right time, but the status bar clock doesn't.
Sometimes, rebooting fixes the issue for some time (it could be a day or a week). If the time display option, from 12 to 24 hrs., is toggled the clock in the status bar is fixed; alas sometimes it just gets stuck again.
Does anybody have this problem too? Is there any known fix?
Thank you in advance.
