Hi guys,
this is my first time using these forums and I wouldn't have done that if the problem was easily solvable. However, this is a major problem for me and I couldn't find a thread nor a solution to it, so I'll post it here.
I have the i9305 4G version of the S3. I have had it for about a month now, and it worked fine, up until now. The phone suddenly starts to restart itself (not reboot!) for about 10 seconds, then goes back to the dashboard.
The problem seems to be the WiFi. Right after I get the "Connected to ... network" message on the bottom of the screen, the phone vibrates immensely once, then everything freezes for a few seconds, then another 2-3 vibrations, before the Samsung logo comes up with the LED light on. After a few seconds again I'm back in the dashboard until I get the "Connected to ..." message, and so on the process repeats itself.
Turning off WiFi seems to solve the issue, but once I turn it on again the problem reoccurs.
Something else I've noticed is that if I have WiFi turned off and cellular data network (for instance 4G) turned on, the "4G", "H+" etc. logo does not appear, even though I'm connected to cellular data! Don't know if it can be related to my main problem.
I have tried everything I'm aware of. Unplugging the battery, factory reset and back up, hard reset, wipe cache pertition. After the factory reset I can use WiFi again, but only for a few hours until the problem reoccured. I THINK once my battery is fully charged the problem occurs.
Note: I haven't even touched stock ROM, kernel etc. Nothing is flashed. Phone is in the same condition as when it came out of the box. Android version: JB 4.1.1
I would be forever grateful if you could help me out here, I can't have a phone restarting itself and vibrating like crazy every 10-15 seconds.
(Sorry in advance if this was the wrong place for this thread.)

UPDATE:
Seems like my issue isn't just related to Wifi. Cellular data network was actually related to my issue, as I first feared. If Wifi is turned off and cellular data turned on, the same thing happens. Seems like the issue occurs every time I try to use the internet either way.
Anyhow, if I let the phone reboot itself without turning on or off anything at all, it will reboot about 5 times until either Wifi or cellular doesn't work anymore even though the status bar tells me that it is turned on!
This seems to be a serious connectivity issue and for the first time I'm suspecting interference with the phone's wireless network hardware. If none of you are able to provider an answer, I guess I have no choice but to hand it in to get it repaired or replaced.
Still noone who has a solution to my problem?

My solution to your problem would be to just bring it to whoever you bought it from and demand a replacement. That isn't normal behaviour.
you can boot into recovery and do a factory reset and cache wipe
if wiping does not solve your problem, just return your phone.
I don't know if this is related, but, I had this issue once (the cause is not wifi though), and samsung fixed (or replaced) my phone.

I'd wipe the phone and return it. This is not normal behaviour and should fall under warranty... Wiping might fix but this may happen again if there is an inherent problem with your handset....

My G1 has recently started playing up. The problems first started with cyanogen 4.1.9999 - it would loose signal, but a reboot sorted this out and it may only happen once every two or three days if that. It was an unstable ROM, no biggy.
But then one day, after rebooting, it got stuck at the android screen then just turned itself off. This repeated several times before it just wouldn't turn on. I left it for a while and tried again later, it turns on, boots but no signal. Rebooting did nothing.
I reflashed (without wiping) cyanogen 4.1.999. and everything seems okay. But then the phone started crashing and rebooting rather a lot, and rather unpredictably. So I wiped, flashed the ADP rom and then cyanogen 4.2.1 rom. This process was a massive brainache - plugging in the usb cable managed to crash the phone within 2-5 min guaranteed, it automatically rebooted.
So here I am. Cyanogen 4.2.1 - after a complete sdcard format, wipe, ext3 repair and flash. The problems still persist! But it's temperamental, a lot of the time I loose signal still, it often reboots itself and hates anything plugged in the usb when it's turned on - making charging the thing awkward.
I used the log collector app to get these logs
http://nopaste.info/17b5351296.html
http://nopaste.info/2e98b9d044.html
At some point during those logs, the signal is lost. The log collector doesn't seem to retrieve a very long backlist, these were taken minutes apart but don't overlap, so I haven't caught a crash. I'm not sure if there are better ways to view logs/debug?
But it's all very temperamental. Occasionally it boots up and life is fine. But more often than not it will loose signal and reboot itself somewhere along the line.
Has anyone come across anything like this before? When it looses reception if I manually try an connect to a network it will say
"This SIM does not allow a connection to that network"

I've read that could perhaps be a problem with the sim... but the sim wouldn't cause reboots would it?
Any advise would be great. I bought the G1 off ebay just under a year ago, so no warranty.
So i remember that i just rebooted my device and next thing i know is, wifi is stuck with 'WiFi is turning on'
Things i have tried to fix it : factory reset, hard reset and when none worked, paid a visit to lg service centre where it started working automatically. Came home, worked just fine but for 2 days.
Now it's been a week. I even flashed stock rom thinking it might be 4.4 rom issue. And nnope. Sane issue. So i guess that means is isnt software issue.
BUT here's what happens. Same modem, mother's galaxy mega2 connects, her laptop connects. I today tried connecting my phone to her phone's hotspot and it connected in first try. Confusion is, i don't know if it's modem that's faulty or phone ( idk if software or hardware )
Also, i noticed when i try to turn on wifi now, it shows no connection available and the wifi icon in drop down menu keeps blinking without being blue. I think it should just turn blue even if there if no wifi to be detected. Sometimes it stops blinking and doesnt turn blue still
It's so confusing
Any help will be much appreciated !
hi, it has almost been two years, did you fix the problem meantime?
hey guys
was using my nexus 4 5.0.1 (stock, bootloader unlocked, not rooted) with no issues this morning. then suddenly i can launch google music. the app launches and i get a white screen with nothing on it. so eventually the app crashes. then i try launching messenger, good play, and many other apps with the same result. my phone begins to get very slow and laggy, nearly non responsive. i restart my phone and i get no service. restart my phone again and a few apps like chrome will launch, and whatsapp aparently, but ive tried so many other apps that will not launch or hang on launch. any ideas? is it a failure of sorts or will a wipe fix the issue?
edit: i think its helpful to note this is a refurb phone. there have been times when my phone suddenly restarts (normal for android) and other times when the screen just goes off and i have to hold the power button till i get red blinks or sometimes i have to plug the phone into the wall for it to restart.
edit2: just restarted my phone connected to the wall. wifi wont even turn on. i waited 60s and it finally switched on. its like the phone has gone limp lol. it wont connect to my mac anymore either ("try reconnecting or restarting your device").
It sounds like your memory chip is failing. I would advise you to extract as much valuable data off of the device while you still can. Then we can troubleshoot to see what the problem really is without having to worry about important data loss.

i did a full factory reset from terminal. im not having any issues anymore.... yet. however im still concerned about potential imminent memory/storage failure.
Alright that's good to hear. Keep us posted.
So this morning my WiFi was working just as usual. But after that I went out so I turned it off and when I return home, my WiFi isnt working anymore. Its not that it wont work completely, but it keeps connect and disconnect. I just can't use it. After an hour I'm going out again so I turned off the WiFi. I was so annoyed by what happened so I decided to play with the WiFi toggle. Guess what, it wont turn on. When I tapped on the toggle it slides to the right remained greyed out, and stucks there. It will not turn on. I rebooted it many times, it worked for about a second then it stops working again. I tried to find out if it was software problem or what, I rebooted several times, disabled root, reflashed ROM, cleared cache, but it still wont work. I even factory reset it by clearing data and caches and reflashed my ROM but it still wont turn on.
Then just now I did a few Google and found out it may be hardware problem and many solved the issue by whacking it at the back. I tried it it worked for a second and the problem comes back again. Then I suddenly remembered that I heard some shaky sound from the upper part of the phone when I shake it. I noticed the sound long time ago but I didnt bother. And I did some sports this morning with my phone in my pocket so I think its the wifi antenna contacts.
Okay assuming it wasn't a hardware problem, is there anything I can try to be more sure that it's a software fault? I did factory reset from recovery. And is that shaky sound a hardware bug or it's normal?
Update: I can't turn on Bluetooth too so it's definitely a hardware problem since they share the same antenna. More over I saw this line in logcat thus making me more sure it's the antenna

Yes it's hardware.
I've been having some problems with my Galaxy S5 recently after ~2 years and some change of owning it. I'm stock rooted on the original ANCG KitKat version.
The problem: If I power off my phone, it will cause it to go into a bootloop, not going past the first screen (Samsung Galaxy S5, powered by android). I haven't found a reliable way to fix it from the loop, but I usually just remove the battery, wait, and try again until somehow it just works and boots up. This is extremely problematic because sometimes my battery runs out and after charging I'll have to go through this game of chance again until my phone works.
The next problem also adds to this frustration as well. When I attempt to pick up a call, my phone will sometimes just not work and restart itself. This leads to lots of confusion and I can't call them back for some time because the phone is stuck in a bootloop.
In the few times that I do get my phone to actually boot up, everything works fine except sometimes my Wifi just doesn't work. It gets stuck on "turning on" where the notification drawer quick setting icon is dim green and never gets to the turned on full green state, eventually just turning itself off (no green color).
I haven't done a factory reset or any real troubleshooting yet, as I'm a bit worried I won't even be able to boot up the phone and I don't have the time yet to spend a full day fixing it. Any help would be appreciated, thanks!
The calling problem may be caused by the google dialer app not being set as the the default phone app but as for the other issues i have no idea a factory reset is a good start though
unfortunately I had the same problem but I have marshmallow but the factory reset helped with the not booting up and see a big difference with the battery
