MAJOR problem - phone restarting every 10 seconds!

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....

4.3 problems

I have Wi-Fi problems with 4.3. Seems to disconnect and be sluggish at downloading. Anyone else?
Also seen some strange flickering sometimes in apps.

I'm having the same issue with the Wifi connection being dropped on both my Nexus 10 and Gnex with 4.3, both were Ok yesterday but have started acting up this afternoon
EDIT: Ok it seems the problem was with my router! Guess I should have checked that beforehand!

I have experienced something similar. Reported in this tread... http://forum.xda-developers.com/showthread.php?t=2384328
I have not noticed that I drop wifi but notice in Chrome (99% of table use is with Chrome) that sometime when I click a link, open a bookmark, or a direct URL that it sometimes just sits and spins for anywhere between 5 and 60 seconds. I never get a timeout and indication I have lost network but it takes forever. Its really random, some pages load extremely fast (few seconds) but sometimes those same urls load really really slow. Don't notice this on my phone (on wifi) or computers and never noticed it on my N10 with 4.2.2. I did a full wipe and installed the 4.2.2 image then accepted the OTA yesterday to see if that would fix it. I'm not sure yet. It seems better but I had a least 1 case where is was slow again last night. This could have been the website so I need some more time to determine if it's fixed...

Although early in the experience curve, on my system You Tube videos are constantly stopping and restarting, waiting for the stream. I rarely experienced that with 4.2.2 so am hoping it is a issue that resolves itself.

Interesting... I find that WiFi has improved on my Nexus 10. At home, my Nexus would drop the network connection periodically and then reconnect about 5 seconds later. So far on 4.3 I haven't seen this happen.

I have no problem with WiFi on 4.3

I've had WIFI issues for as long as I've owned my N10. It just recently stopped working (couldn't reply in hangouts) so I turned off WIFI. When I turned it back on, it would just say authentication error. I had to reboot the N10 to get it to reconnect.

I noticed the ytube issue too. I changed from auto to 2.4ghz under advanced and so far seems better but not sure yet..

Well no luck with 2.4Ghz. The issue is very sporadic, sometimes everything works great and but then all of a sudden Chrome takes forever to access a new url. I have determined it's not Chrome, it's just that is what I mostly use on my tablet. I have seen this several times in Youtube and so when this happend i grab my phone (on wifi) to see if it could be network related but everything works flawlessly on my phone. I started doing some speeds tests to help troubleshoot this issue and the wifi performance is across the board whereas it's very consistent on my phone wifi. When I had one of these delays last night I immediately switched over to my speedtest.net app and it reported that it could not access the internet! My wifi signal indicator never indicates that I have lost wifi. Definitely something strange going on here. I have already factory wiped my tablet twice (originally going to 4.3 and after to troubleshoot this issue) and it never happened on 4.2.2 or on my Phone wifi there had got to be an issue with Wifi on 4.3. Just wonder why more people are not having issues. I might try swapping out my WAP but considering all worked great on 4.2.2 and it currently works fine on my phone wifi that would frustrating if it turns out to be my wifi.

Followup: The YouTube slowdown continued and after a few hours the internet connection became so slow that it would take several minutes to load a single web page. My internet connection on my Mac acted normally during this time. In the end I could not even get text pages to load in the XDA app. After rebooting several times, cleaning caches, turning wifi off and on, cycling thru the wifi advanced options and flashing the Monkey kernel I finally gave up and restored a Rootbox nandroid backup. My roadmap to the 4.3 install was: formatting all memory (including data/media), restoring my rooted stock 4.2.2 nandroid backup, and then fastbooting the JWR66V from JDQ39 OTA zip file. I then re-rooted by installing Chainfire's Update-SuperSu-v1.43.zip. I have no idea what I did wrong with the installation but will wait with 4.3 until updated 4.3 custom roms become available. Currently I am very satisfied with Rootbox so waiting is not an issue.

Has anyone with those problems tried to turn on/off WiFi optimizations in advanced WiFi settings?

Yes, tried that and it didn't help. I'm now torn between going back to 4.2.2 or staying on 4.3 cause I just picked up a Miracast adapter... Man i hate it when they create new bugs with things that had no issues in the first place!

I figured out that my laptop makes the wifi on my nexus VERY slow.

I have found that switching to my 5 ghz setting on my Asus router has solved this issue for me.

Since 4.3 has anyone else found that copying text from pretty much any application crashes the app?

Note 4 (T-Mobile) Lag, Freeze, Crashes, Restarts.

This is my first post on this forum. I searched around here for a solution, didn't really find one matching my problem. I am not a phone wizard or anything like that either. So I'll try my best explaining my problem.
First things first:
Phone: Note 4
Model #: SM-N910T
Android Version: 5.1.1
Rom: Stock Rom
Rooted: Rooted Once and used a custom Stock T Mobile Rom Once.
Here's the ROM I used at the time: http://forum.xda-developers.com/not...10tuvu1cog2-debloated-deodexed-stock-t3175406
Recently I So recently my phone out of the blue started lagging, freezing, and restarting itself. I didn't download any applications or anything like that for it to freeze up. I was currently then on the custom ROM I have mentioned above and it was the updated version. I have tried everything to my knowledge to try and fix the problem. I have tried going back to stock T mobile ROM (currently on stock rom now) through odin and stuff. After all that, it was still lagging, freezing, and restarting etc... Ran it through safe mode and the only problem in safe mode is that the lag is gone, but the restart is still there. Running in safe mode, if I would turn the screen off and back on to unlock my phone, there would be like 40% chance that it would restart after unlocking the phone and the phone would just restart normally. Rarely, whenever my phone would attempt to restart.. I would get a "Could not boot normally" message along with couples codes below and the image of android guy. Then I would have to take my battery out and attempt to restart the phone once again.. I've wiped the cache and everything in recovery mode, nothing helps at all. Also, the phone is in perfect condition. Hasn't been dropped, cracked, no water damage, or anything like that.
This place is my only hope to fix my phone before I will go out to buy another phone from the carrier.
Thank you all for taking your time to help me

Well I already got rid of my note 4 unfortunately before anyone could help me here so I had to upgrade my phone to note 5 and return note 4. While I still had my note 4, I realized something weird. While the phone was lagging and crashing etc.. When I had it plugged in for charge it would work perfectly fine. No lag, it wouldn't freeze up or restart (had it running perfect for 7 hours). It was like my phone was brand new again. As soon as I unplugged it from the charger, few minutes in and it was back to restarting and all that. I never knew why it did that.
Anyone know why this mightve happened?

Might be the battery though

I thought that too. I tried my brothers note 4 battery for awhile and it worked for a little bit and then it started doing the same thing even on his battery. Shrugs.

In the COH update iteration there is an annoying bug that affect fingerprint.
The bug causing the phone to restart, lagging & closing all apps randomly when the fingerprint is set.
May be this one is also the same.
Try to disable all fingerprint related settings.

Unable to turn WIFI On.

Hi there, I had my phone for about 5 or 6 months where it was fine till recently.
The problem was that I am unable to turn the wifi on. in the main settings the slider is greyed out and a text is on screen saying turning on WIFI but it does not. it does not even show the list of networks. it quick settings it shows as searching but nothing is listed.
in the about phone settings it shows the mac address to be 02:00:00:00:00:00.
This occurred a few days ago but no new software was installed the most recent being a week before to the April security update.
I have tried multiple things such as turning on the airplane mode then off, switching phone on or off, safe mode, factory reset, wiping the cache, taking the sim out.
There has been instances where I am able to connect to a wifi network but it does not last long (few mins) except when taking the sim out which lasted about half a day. (tried again but did not work)
My phone is not rooted and has the stock rom.
There has been some research on this matter where people have done something with the presist(I think that is what it is call) folder but there was no result on it so I have not tried it due to wanted to keep the phone unrooted due to warranty concerns.
I would love some solutions in figuring out this problem.
Thank you for your time.

Apps constantly reloading/refreshing

For the past several months my apps have been having an issue where they will refresh/ reload while I'm using them. Facebook goes black a scrolls back to the top of my feed. Games restart and reset to the main screen. While typing in certain app text boxes, the app will restart and I will lose all info that I typed.
I am currently on pi3 mm firmware as this was my last effort to troubleshoot the issue. The issue is present in all firmware past pi3. Anybody experience this??

Quick update, the issue completely disappears when I switch on airplane mode and use Wi-Fi only. My line is suspended so there is no service to the phone and I typically turn data off just in case. Just to be clear the issue IS present when on Wi-Fi and not in airplane mode.

I've ODIN'd both nougat and mm firmware several times as well as trying different roms and the issue seems to be present. It didn't start until after the nougat update and has only worsened since I turned off the service to the phone and use Wi-Fi only.
