[Q] App froze -> Reboot -> No signal -> fixed after reboot. whats wrong? - Galaxy S II Q&A, Help & Troubleshooting

Today's morning my phone freezed suddendly and didnt respond.
I didnt know how to close the app that caused it so I rebooted it and it came back right after a few seconds, but with no signal.
I tried pulling in & out simcard or flight mode with no success.
Only after I did another reboot it was fixed and I could get signal again.
What happened? Should I be worried about it?
Im running cognition v1.5 & SpeedMod T27

I have seen this happen before. It's like the entire system freezes and then resets itself. I don't think that the phone actually did a full reboot the first time since you said it came back on after a few seconds. Either way I wouldn't worry about it so much unless it becomes a frequent thing.

[Q] phone shuts off please help

This typically stems from not wiping data as well as cache prior to flash...
Sounds like you have a rogue app locking the phone up while it's sleeping. I would do a factory reset, then install your apps one at a time until you figure out what's causing it. Allow the phone to sit idle, and maybe even reboot between installs. Allow the phone to settle down and enter sleep between each install and then try to wake the phone after it has been idle for a minute or two.
The other way would be to try looking at logcat with your phone connected to your computer when the screen is on, then when the display turns off and the phone sleeps. Odds are, whatever is causing the problem will be the last thing displayed if logcat stops giving you output. Otherwise, it should just repeat the same thing over and over (I'd assume so anyway) when it's trying to wake up from sleep.
My friend was having a similar problem so he flashed from SC 2.9 to the Deoxed eb01, wiped all the data on his SD card, and reflashed to SC 2.9, he hasn't had that problem since.

Media scan , kies connection loop?

Sorry another bug thread.
So i was at work playing some music on my power amp app, then i hear the connection sound and my battery has a lightning bolt sign like its plugged in ( but it wasn't ) also media scan is constantly scanning my sd card and i slide to unlock my phone and the kies connection to pc screen is up.
So i switched off my phone, pulled the battery and sd out and restarted.
It went back on and still same thing but my battery dropped from 98% to 82% ?
After a few more it stopped.
My phone has ke7 firmware. I have no idea what caused it to do this any ideas?
Sent from my GT-I9100 using XDA Premium App
i am having the same problem, my phone does this 3 - 4 times a week. Thought it would help to change roms so i went from stock to litening, it still happens.
Anyone know a solution or what is causing this scan loops?
Has anyone found a solution to this problem?
It started for me a couple of weeks ago and now it happens everytime I finish recharging my phone.
I tried to go back to a stock rom, but it did'nt fix anything, and I'm now running Cognition S2 1.15 where I experience the problem every other day. I've tried with different roms, but it dos'nt fix anything.
In order to get my phone to work I have to reboot it 4-8 times, otherwise it will continue to do a media scan from time to time, my battery stats won't be accessible and I will have lower battery, if I don't reboot it.
Any ideas, is it a hardware fault?
my phone started doing this tonight when I deleted a file (folder with some JPGS, folder from an app that had been uninstalled) and a media scan loop started.. phone turned off after two min.. now it has been doing it since, I have to remove battery to get it to turn back on .. it then commences the loop again.

Clock wont change time??

The stock android clock on top right of my screen wont update! Say i turn phone on at 1:20, it wont update to 1:21 or ever change unless i reboot then it will have the correct time for that ONE minute. I haven't recently installed or changed anything like apps or anything. BUT the clock on my lockscreen(widgetlocker) updates and works fine and is accurate. I went in date and time settings and its set to automatic, in the greyed out "set time" it shows a correct updated time, however this time isn't being shown up on the top right of my phone. I tried putting it in "manual" mode instead of the automatic mode and it still wont update..Ive reboot and pulled the battery several times to no avail. Im runnning stock rom and kernel, just rooted. As i said before i havent touched any new apps or settings in several days. This is really annoying as i cant tell what time it is while on and using my phone without going to the lockscreen and it just now began happening. Anyone have a fix or also have this issue??
I'm having the same problem today with my HTC Inspire 4g. Like you I have done nothing to my apps and its getting annoying. My phone has Cyanogenmod 7 flashed onto it.
i had same issue . made a phone call to make the phone get the auto time change then rebooted for good measure
Wow, mine was related to the time change, apparently! As soon as it reached 2am where i am it started working fine again!!(Time change was at 2am here)

Galaxy SIIX SGH-T989D crashing issues

Hi,
I'm looking for some general advice and troubleshooting for my phone's issues. My phone started crashing very often, sometimes at complete random, as well as when I was using it fairly heavily (any app that froze my phone for a second before loading before the crashing would now crash my phone). Sometimes it would reboot fine, other times it would bootloop once or twice before reloading fine. I previously tried doing a factory reset, removing my external microSD card, and updating everything via Kies and nothing worked.
I got bored and rooted my phone, did a full wipe, and flashed the latest Infamous update. The problem was still there but it wouldn't crash as often while using it because my phone could handle higher app activity but it's still there. Oddly enough, after flashing Infamous, it often fails to reboot and so I have to do a battery pull before turning it back on, otherwise it won't even vibrate after holding the power button.
I'm just wondering if you guys have any idea what the issue could be. Is it likely still something I can fix? Is this potentially a battery issue or is it a hardware issue?
Thanks so much!

Unstable Nexus 9. Sluggish reboot 3 times in 15 minutes EMMC issue?

got home last night from work, started using my nexus 9. I placed it on the bed screen went off. a few minutes later tried to use it again,
noticed that it was very sluggish, apps did not want to load. everything running very slowly. Then screen goes off again and it restarts. takes a while to restart about 2 -3 minutes, then comes back very sluggish again, I tried to load apps, it restarts again.
At this point I am about clear cache and start trouble shooting , did not get to wipe cache. it starts back up again, then does not run sluggish I am able to use it. been fine since yesterday.
Wondering if Internal Memory card is going bad I read others having similar issues, Not sure if I should send mine back.
I do not want to be with out a tablet.

It could be a rogue app as well, but did you try a factory reset? If that continues after a reset then just get a replacement.
it has been fine since I have not tried the reset yet, but I will if the problem comes up again.
