Hi, I never root my phone or flash a custom ROM.
The problems was started when I flashed a new ROM from sammobile of another country, my phone comes with 4.2 and I flashed a 4.3.
I flashed newer ROM from only Vodafone-Spain (only those really are my official supplier), and then I update ever with Samsung KIES, (no Knox counter)
So, with Andorid 4.3 I had more problems than now with 4.4, now the only problem is with WIFI
I can use normally, with screen ON, the problem is when sleep for a long time (more than 1 hour) when I touch a button I see the unlock screen, but does not seem to work the touch screen, and screen go off after a seconds, if I touch other button the screen don't go on. And then, after aprox 30s it reboot itself, and show a window telling that the Process System is not responding, do you want to close?, and two buttons, close or wait.
I tried to start my phone in Secure Mode and I have the same problem, so it is not an app, it is the ROM.
I do at least 2 Factory Reset, but the problem is still there.
I think it is a software problem and not a hardware problem, because the problem start when I update to Android 4.3
I tried the trick WIFI Power save Mode OFF (on dialer, *#0011# -> WIFI -> Power save mode OFF) and never reboot automatically, so the problem I think it is with this power save mode. But if I turn off, when WIFI is ON, the battery drain fast.
In the samsung shop they tell me that first will format my phone to see if the problem solve and try for a time, if not solve, then I have to send by mail... and I will not send it because I know the time it will take to repair it is about 1-2 months and I need the phone for my work.
So is there another solution or something to try?

Since the first ROM (4.2) I flashed 3 or 4 ROMs from SamMobile, so I am not very optimistic. But I don't lost nothing, I will try it
I flash again the ROM, and after 2 days testing, the problem is still there.
Any other thing to try before send to samsung?
Please, give me another idea to try. I really have a problem with WIFI
This is how Wifi (some times) drain my battery when are not connected to a network. But the problem is worst when is connected, because it freeze and reboot.
Hello! You could fix the problem? I took suffering the same problem as your months, and I have not been solved, I'm for kicking the **** mobile! As may give so many problems with the wifi?

Yes I solve. So.. I don't solve it, it solve it self. One day I saw that I don't had wifi connection, then I saw that I don't any WIFI names stored, all was erased automatically, I don't know how.
But the result it, I don't have anymore a freeze or a reboot because wifi. ALL, absolute ALL run fine now. I had a lot of WIFI names stored, about 30-50, maybe this was the problem, a conflict with some of these names, but I'm not sure
No one update, reflash, factory reset, or start in safe mode was solve any problem, the problem solve it self... very strange.
If you try a factory reset, then don't restore all your mobile config. Try to install all apps manually, one by one. I ever restored my backuped config, and I think this was the problem.
Hope you can solve it

Thank you very much for answering so quickly.
Happens to me exactly what you do, but seems to have no solution.
I have tried more than 8 roms, stock or mods, and always fails.
At first I thought it would issue the modem or kernel, but after many tests, I do not ****ing know what is causing the problem.
I'm running out of solutions, anyway thanks for telling your case...
I'm glad that in the end one way or another, you have it fixed.
:good:

What happens when you fully wipe, flash a 4.4.2 rom, don't restore anything, not even your google account and don't install any apps.

Thanks for your interest! The truth is that it is very strange ...
If I remember correctly, already try what you mention me, but I kept going ... It's like at some point something had happened which change roms not seem to solve..
I'm considering installing a rom with 4 files and pit file, but do not know if this will help in something
Let's see if I can come up with the bug because it is becoming a pain in the ass
:good:
I would try what say Lenny1988. So the only change before solution and after solution, was a big crash on WIFi drivers/app/modem (don't sure) it self, and was deleted all my stored wifi access points that I had. It was a problem related to Wifi power save, if I disabled it then I had no reboots/freezes.
So, I would try a factory wipe and DON'T restore anything, and try for a couple days. If work, then you know a way to solve it.
Tell us if it works.
Hello there! I will update with the latest news!
I tried the recommended advice, but no luck...Not seem to affect him leave without restoring.
The only thing that seems to work and keep it running, is to disable wifi power saving system
you know....
Code:
1. Go to your phone dialer
2. Dial *#0011#
3. When you see the "ServiceMode" screen, press the left menu button
4. Select "WiFi"
5. See that "Wifi Power Save Mode" button that is "ON" - well turn it "OFF"
But this way drain your battery much faster,so it does not seem a good solution to the problem.
Curiously, the same phone, some people suffer this problem and others do not....
It may be hardware? or software?
If I find something, I'll note here.
Regards
Recently i noticed wrong time after restart and the device didn't update it unless it's connected to Wi-Fi. I did some research and found that the device connects to ntp servers via udp 123 port. And most common issues is provider limitations on this port. Asked in provider's support forum and result is that is set some limitations and probably will experience issues with it. So for know solution is to find why my gt-i9505 forgets time after every restart? I own and HTC Desire Z (Vision/G2) as work phone without data plan but it keeps time correct. Both running CM11 (4.4.2 on DZ, and 4.4.4 on S4). Tried to uncheck "Automatic date & time" but isn't helping. Any ideas?

Seriously, no one?
Just a guess - kernel or hardware issue. Maybe it is worth to flash newer or different kernel.

I'm using CM11 and they releases new update almost everyday, so different kernel will no last long (i presume flashing roms updates kernel too?)
And also the time after reboot is set on random basis from 1970 to... pick a year from this century. I guess to ask in cm's forums is the best thing to do next...
Have you tried factory reset after problem occurred. I have searched in Google and there are lot of phones experiencing the same problem.
One says it is CWM problem (?strange), some do a factory reset, some re-flash firmware... So, start with most acceptable to you.

Yes, this was first i did. (with stock rom had no issues). Yes i'm using CWM, what is next best choise (till madmaxx82 release 4ext recovery for jflte)? On My phone CWM acting weird, for example backups are created in /data/media/clockworkmod/backup instead of /sdcard or /sdcard1
EDIT: TWRP flashing in't solve issue, even when set appropriate time zone
i have a nexus 4 running CM 11 M10 and i flashed the roam around 2 weeks ago and now this strange bug has showed up, the wifi doesnt work.
The device connects to wifi but the connection is only partial, the icon doesnt go from brown to white and thus i lose access to many features like the play store and google now. This bug has showed when my phone was running Paranoid Android and CM 11 M8, has anyone else had this issue? It happens for mobile data as well. Anyone know a fix?
My phone has been factory reset and everything. Ive also recently installed and used freedom, could that have caused the issue?

Uninstall freedom - that is directly using your network hardware -- if that doesn't affect the problem you could re-install it.
Have you tried it with another network router - or just on another network you have access to? You could restart your local router, clearing any ip assignments that may be blocking your phone from connecting.
IF you have access to your router and admin rights you could TEMPORARILY disable encryption to see if the problem goes away.
To test the likelihood of hardware failure, you might want to restore the phone to factory software -- NO custom roms/kernals no extra apps and then see if the problem occurs.
Cheers.. hope this helps
Well okay.

Are you running the latest modem? I believe the most recent version is 1.03.

as you probably noticed im a novice at this, i dont know how to check if mines the latest and how to update should it not be.
Go to settings, about phone, and look under baseband. The last 3 digits will tell you the baseband. Mine says 1.03.
Yeah

Yeah! mines 1.02. how do i update?
1.02 is a very recent modem and that probably isn't the problem. I suggest flashing back to a stock ROM and test it.
The radios are flashable from CWM or TWRP: http://forum.xda-developers.com/nexus-4/general/ref-mako-modem-collection-t2087227
I've been using local cast for a long time now it recently started acting up so I made use of the restart Wi-Fi button since then I cannot connect to any wireless network norsee see one. Any ideas?
Stock or custom ROM? Custom kernel?
Same thing happened to me after upgrading to CM13 nightly from 7/7. Haven't been able to get it back since even after wiping system, data, caches and reinstalling.
Are you using ElementalX kernel?
Last update causes this. Revert to previous version.
ok

I have done a bit of research, apparently the vendor image has to be up to date with the ROM but the problem is if I get the ROM dirty unicorn I could not find any vendor image for their ROM version 10.4 latest one. I don't understand whats happening with the system but this WiFi problem has recently occurred to many people.

read tge F. A. Q on the first page of the rom version-thread you are interested!!!
JiaYu S3, Nougat 7.1
Did you try to reinstall the rom? Doing again a full wipe.
That MAC looks weird to me...

mac address changing
can someone help me.. im using Nougat rom Stable 3 for Jiayu S3 MTK6752.. my wifi mac address always changes when im rebooting.. and i need to connect to the wifi again when that happens.. can someone help me on this? thanks
it has been covered again. people with that phenomenon just do something wrong with wiping data.
Anyway now that you are into this state. Take a backup wipe for factory reset from twrp and try to install RC4 from recovery. Check if you have the same behavior with the WiFi mac address and report.
If ok, then try to wipe data/cache /dalvik, and install 7.1 stable 3 again.
Used TapaTalk with JiaYu S3
Here same with wrong MAC Address 02:00:00:00:00:00. Everything began when I rolled back to RC5 from Nougat to try fix WiFi dropdown because of conflictive 00:80... MAC Address, as detected in other forum threads . I did it with Flash Tool and using "Firmware upgrade" option. Everything was good, and WiFi was as stable as I wanted. So, when I came back to Nougat 7.1.1 via Recovery, firstly everything was good, but one day I had to remove battery for its replacement. When I switched on again... OPS... No WiFi and BT and MAC Address 02:00:00:00:00:00 Of Death.
Since then, I have to make all the process again (Flash Tool to RC5, then Recovery to Nougat and reinstall and configure apps and accounts) to make WiFi restores 00:80... MAC again and work again. But now, everytime I have to do a reboot and/on shutdown it's like a russian roulete: sometimes WiFi/BT breaks again. And this happens ALWAYS when I remove battery.
I have tried from "soft" solutions (installing ChameleMAC, but just solved the problem once) and even "hard" ones (using Flash Tool in 'Format all+Download' mode, and recovering IMEI later). But nothing makes to keep MAC address stable and fixed.
Just I think some new things to try. For example, use the 'Format whole flash' option, and format Bootloader too, but I am afraid to brick device definetively (there is no much clear documentation about that aggresive format for Jiayu S3 or in other devices). Or maybe I am wrong by using RC5 everytime (I tried one time to rollback Kitkat Stock ROM, but it didn't boot and I was sure I chose right ROM, S3A 16gb; I had to 'revive' device entering in META mode).
I am not so expert about this device, but my diagnostic is, maybe NVRAM corruption. I have not find any documentation about similar problem and how to restore NVRAM in order to fix that kind of issues that 'rolling back to RC5' does not work.
So, do you have any ideas about how to solve hardly this issue? Or am I condemned to not to open or switch off my device nevermore ?
Thanks in advance!

Check to install the RC5 Repacked that exists also as thread here in xda. Then boot at least once into the RC5 and be sure wifi and Bluetooth are working.
Then install the proposed TWRP that is mention in FAQ of the madOS thread for installing 7.1.X
P/S. There are ppl that mentioned that when enabling device encryption then they loose the Wi-Fi. And when they disable it again, Wi-Fi is working normally!!!

1 use SP Flash Tool flash replace Recovery to MAD TWRP 3.1.1-0 and the latest LP5.1.1 RC5 and ，the WLAN and BT is fine,
2 wipe the artcache/cache/system/data/Internal storage，
3 format DATA
4 unmount /system
5 flash the MAD OS v11 2017/05/27 ,bean GApps，SuperSU 2.8.2 at once
then WLAN MAC Address 02:00:00:00:00:00，BT not work
