[Q] Why does my Wifi & Bluetooth not working even with stock rom?

Hey guys,
I have a Galaxy S4 (i9500). I installed Omega ROM v22 on it and everything went smoothly, Wifi & BT working perfectly.
After a few hours of using the device (nothing special at all, texts and stuff like that) - I noticed my wifi isn't working and by not working I mean that I click the wi-fi button and it changes from gray to the mid-state between gray to green for around 20 seconds before it goes back to green ago.
If I open the menu to see my networks it just says "Enabling" without any networks there.
I had to drive somewhere so I went to my car and tried to enable Bluetooth, and same thing happens there - Bluetooth will not turn on and will stay stuck on mid-state between gray and green for a while and go back to green.
I flashed omega rom v22 again and the problem was gone, or so I thought. I went back to the car for another drive and realized the bluetooth issue is back - and when I got home I realized the wifi issue is back as well.
I figured I need to reset everything so I tried the following:
Full wipe (including dalvik and even including "internal SD card") and then flashing stock rom (from the official website, stock rom of my country).
The issue was back after a few hours. I do not have BT or Wifi access. Yesterday Wifi suddenly started working for a few hours but then it stopped working again.
I really need help! I have no idea what to do with this issue!

Well rule number one when you have problems after flashing without wipe.
1. perform a full wipe and see if the problem persists.

Tried that, no luck.
What else would you try?
In some places when people had problems with Wi-Fi they said to flash a different kernel but I don't see why I would have this specific issue with Omega Rom and why the default kernel with it wont work well?
Maybe this could be a root issue? My root works fine but I have this weird gut feeling like this is some permissions thing that's going on.
I'm trying to think why it would work right after the wipe but then stop working shortly after.
Another symptom: It randomly started working for a few minutes and then stopped again (around three hours ago).
Any idea what's going on?

Well, if you fully wiped and didn't restore any apps and settings then it can be two other things.
Or it's a bug in the rom or a hardware failure in your phone.
I would suggest trying a different rom first. Do not restore anything, not even your google account.

wi-fi fix?
Do you actually have an i9505? or is it a canadian or att version? if its the latter sometimes the devs offer some wifi-fixes, also try a different kernel. otherwise it could be that your radio/modem are not compatible with the version of the ROM you are flashing.

Tried arrow ROM and this issue doesn't seem to happen in this rom. Hope it stays like that...

Sadly, it did happen with this rom, after just a few hours.
I'm now using stock rom and still suffering from the issue.
Does anyone have ANY idea what I can do to fix this?
Thanks in advance!

[Q] SM-G900F (Date & Time problem with [klte] 4.4.4 ROMS)

Hi all,
I've recently upgraded from a Samsung Galaxy S3 (i9300) to a Samsung Galaxy S5 (SM-G900F). Phone seemed to be working as desired so decided to go ahead, root, and install a custom ROM for enhanced functionality and customisation. Root process went smoothly, just running a simple CF-AutoRoot with Odin3 (voids KNOX, but no other problems), then installing PhilZ Advanced CWM Recovery.
From there I decided to install an unofficial build of CyanogenMod 11; found information on this forum. Flashing worked perfectly (and took rather little time!), but upon installation I noticed a strange problem. If I hard reboot (power off, power on) the device, with Wifi & Mobile Data off, the time and date are reset to incorrect values. Usually 01/01/xxxx and the time around 00:00. Same problem occurs even if when I turned off Network-allocated time and tried and set time manually.
The same problem occurred with other similar CyanogenMod based builds such as [AICP] and [AOSB]. I decided to restore back to the stock ROM and noticed that the clock and date were set correctly on reboot (and also on custom versions of 4.4.2 such as SpeedROMv7).
I checked with the terminal the value of the 'hwclock' (from BusyBox) and it reported an odd date somewhere in 1970, but different to the ones in found on CyanogenMod etc.
Does anyone have any idea what could cause this kind of problem and how to fix such an issue? If anyone wants any additional information about my device, please don't hesitate on commenting in this post. Would be grateful for any feedback. Thanks! :good:
PS: Also seem to be experiencing a problem with WiFi randomly disconnecting after a period of time. Not seen many threads with this said explicitly however. Problem with no voice in phone calls with headphones still persists but I've acknowledged that this is a known bug at the moment.

Same Issue.

I have been encountering this very same problem for a while now, in fact, I am expriencing the same issue with my Galaxy S4 (i9505). So this must really be an issue of the CM code I guess.
Any ideas on how to solve this would be welcome since it is a really annoying issue

Please help me in fixing rotation problem in samung s5 (g900w8)

I have read too many posts and solutions but nothing have solved my s5 problem, which is not rotating.
I lost rotation after flashing a new rom on my s5 (actually suddenly after two weeks of installing the new rom).
I have to mention that if I removed the battery for more than a min, "sometimes" it works again but not for long time, and when the screen shut down it stops from rotating.
I downloaded cyanogenmod roms but also didn't fix it.
I tried to reset my phone using kies, and it worked back for one day, then stopped.
I also tried the method of replacing libgnustl_shared.so file in system/lib and changing permission (as described in this thread http://forum.xda-developers.com/showthread.php?t=2644293), but it didn't work with me.
Please, I am so desperate to fix this problem. Anybody think it is a hardware problem?, if yes, why it works after restart with battery removal sometimes?
I am eager to solve this problem, and thanks for everyone who wants to help

Bluetooth not working with 7.1.1 aosp stable x - Jiayu s3a

Hello,
First of all, sorry for my bad english, i'm french and not very good
Thanks for reading me and the help you give me on xda (even if i never post, i always find my solution on the forums )
I'm actually on CM13 6.0.1 20160810 beta, working quite good since then, but my system is going completely drunk, my sim is not working any more (only my sim), wifi problems etc.
Factory reset is a solution but i have to setup again all my apps, so I want to update to 7.1.1 and then setup all my apps on a new rom without the bugs i used to.
I create this thread because i tried to install MAD Team aosp 7.1.1, stable 7 and also stable 8 and succeeded, but bluetooth is not working...
The problem i have is when i install this rom, bluetooth is written as "Disabled", and when i turn it on, it stays greyed 10 seconds and returns to OFF.
I tried many things :
-install starting from CM13 with factory reset
-install starting from CM13 without factory reset
-install starting from CM13 with format data
-install official 5.1 after factory reset + format data, then install 7.1.1
-factory reset after installing 7.1.1 with all methods over
I'm out of ideas, not finding useful things on the web, even on XDA threads :crying:
It's not hardware problem, my BT works perfectly on CM13 actually, and when I reinstall CM13 after a 7.1.1 fail (with or without restoring my data), it works again...
If you have any idea, i'm desperate :fingers-crossed:
Thanks for your help

I had the same problem the first time I enabled Bluetooth, but rebooted the phone (just one time) worked. Now Bluetooth works perfectly.

Thanks for your quick answer, I tried it this morning but no result.. :crying:

Wifi not turning on (i9505 - Stock rom)

Hi. After trying a couple of custom roms, I wanted to go back to a stock rom via Odin. I actually succeeded. The phone boots, and android setup screen comes. But in the "wifi connection" screen, when I touch the button to turn the wifi on, it just refuses to turn on. It goes back to off position. I have tried several different country's stock roms (4.4.2 only, I haven't tried 5.0) and they all ended up the same. I just can not turn wifi on in stock rom. Wifi works in custom roms that I installed using TWRP.
Any idea why this happens?
By the way, I also tried flashing different modems, but the result is the same. I read that turning off the phone and removing the battery helps, however, in my case, it didn't.
Any help is greatly appreciated.
EDIT: As I have looked into the issue, some people claim that a custom kernel usually solves wifi problems. I haven't tried it yet but I will as soon as I can get my hands on the phone. Also in another post, I have seen a build.prop tweak "ro.securestorage.support=false" which is claimed to have solved the wifi issues. I am writing these to be of help to others that might encounter the same problem. I will update the post after trying these ideas.
EDIT 2: It turns out, when you flash a stock rom, Odin can't actually flash the modem partition. It seems like it does but it actually fails. You have to do it twice.

No Wifi
Hi,
have some trouble with my Galaxy S4 (GT-I9505). Since 2 weeks I'm trying to get wifi working. 2 weeks ago I decided to root the phone (everything complete stock Android 5.0.1). At this moment wifi was working well..
I did:
- Flash TWRP with Odin
- Flash magisk 18.1
--> booted phone..
Everything seemed to work well..expect wifi. It wouldn't turn on. When trying to activate the WiFi button by sliding to the right it stays grey and after 10 sec. the slider goes to the right side again.
What I've done:
Downloaded several stock firmwares from sammobile --> no wifi
Flashed serveral custome rom's (lineage 14.1, 15.1), android 5.0 and 4.4 based --> no wifi
Tried differnt kernels --> no wifi
Flashed different bootloaders and modems--> no wifi.
Tried to delete files in /wifi folder suggested here in forum --> no wifi
Tried to modify buil.prob set the security value to false suggested here in forum --> no wifi
I don't think thats a damage on the hardware. It must be a software issue?
Bluetooth and mobile data are working well. GPS and wifi seem to be broken.
After spedning weeks of flashinng, recovering etc.. I am frustrated and don't know what to do.
Any advices?

My wifi is not being enabled with this rom. Does anyone know how to solve?
