Bluetooth malfunctioning - Android General

My Bluetooth on my Galaxy Tab S 10.5 has been working a month ago. Haven't used it ever since. Today I tried to turn it on, and it just reverts back to off in 3-4 secs.
Tried clearing Bluetooth cache and data, as well as system cache and dalvik cache without success.
Is there anything else I can try? What worries me is that it doesn't seem to be a common issue.
I am rooted, stock rom 4.4.2, haven't done pretty much anything extreme at all.
I read on some sites that doing a soft reset usually fixes this, but the battery on this tablet is not removable, so how can I do it?
edit: also - unrelated - first time I turn off Airplane mode in a long while, how the hell is it possible I have 3-4 signal bars even if I don't have any SIM in?

CM7 Galaxy LTE post airplane mode no data issue

So, everything works great, except when I activate airplane mode via settings or notification menu, a problem occurs AFTER airplane mode is de-activated. Only the cell network is active, neither edge nor 4g connection is available UNTIL after a reboot. WiFi CAN activate but no cell network DATA available.
I attempted to:
1. search forums and google (similar issues noticed, no solution available)
2. flash stock Rogers radio then re flash CM7, didn't solve
3. Redo APN seetings with different inputs, didn't solve
4. shutdown remove sim, startup no sim, shutdown reinsert sim, startup, didn't solve
5. now on stable (seemingly faster) UCLA3 modem didn't solve
wipe emmc etc., flash SkyIceCream ROM, and then the problem solved!, wipe to factory and wipe cache, flash back to CM7, and the problem returns!
So I'm thinking it's the kernel and/or ROM. My device doesn't FC or SOD atm it seems very stable.
I use airplane mode a lot since I do travel on airplanes quite a bit. I can reboot after airplane mode every time but it's a pain plus sometimes I don't have the time to wait for a reboot literally. Please help, I love the ROM.
Hey brotha - I had a similar problem with mine. When we went on a trip to Phoenix, it took a good 10 minutes or so for the bloody network to come up. I had a bunch of data charges too when it did finally come up... but no description except medianet data charges (sent data not received). My wife's iphone also had some large charged data for sent. I don't know what it was, but the Phoenix market has LTE (obviously nothing to do with the iPhone) - but I figured that because our home network was not the same (4g here) that was a lot of ATT internal configuration fighting going on and it took a while for their systems to parse it out. All speculation and what not, but reboots on my phone wouldn't help until if finally popped open, but I'm betting it's not a device problem, it was a network issue (based on the 60ish meg upload charges we both had our our different phones... and no, we weren't posting airplane bathroom porn to youtube...
I couldn't take it anymore so i flashed nexusmod4 and now i don't have airplane mode problems anymore. So for anyone having this problem on CM7 don't worry you can fix it by flashing another ROM.

Another Wifi Problem P6210 (SOLVED)

Two days ago, my device suddenly could not connect to any wifi anywhere, encrypted or not, WEP nor WPA. This began to happen after I did a backup though CWM.
It sees networks but continuously runs through a scanning, connect, disconnect, scanning cycle. It tries to set the IP from the network, but then flashes unsuccessful and starts scanning again and repeats the process, and in the list of available networks, all available networks cycle between being not in range, remembered or disabled.
Sometimes wifi networks are greyed out, sometimes, not. Sometimes it cannot even find my router, even if I place the Tab on top of it. It connects once in a while, randomly, but only holds the connection for a few minutes.
I have other wifi tablets and all can connect to my wifi, nothing has changed with my wifi settings, router, etc. But to make sure, I did cycle the modem and router on and off and even reset the Airport Extreme that I use to factory settings. Modem is new and Airport Extreme is only a couple of months old.
My Tab is rooted and running stock HC. Never been dropped, great condition, never exposed to shocks, water, etc.
I have tried the following fixes:
Restored to factory settings, wipe data, etc. Nothing. I have tried this several times.
I have tried setting a static IP address. Nope.
ODINed it back to stock using P6210XARKL1_P6210UEKL1_HOME.tar.md5. It briefly connects to wifi long enough to apply the update and after that, it starts cycling scanning, connecting, disconnecting, etc. Tried this several times as well.
I even tried the update to the UK ICS for the P6210 and have the same problem. It sees wifi, but cannot connect, and on occasion it cannot see any wifi at all, even when I am 2 feet away from the router.
At this point I am convinced that it is a hardware issue (either that or it is pouting because there is a new Nexus 7 in the house)
Anyone have any other suggestions for a fix?
Update:
I did another hard reset from within Settings-->Storage--> Factory Data Reset, rather than through recovery (either stock recovery or CWM) as I had done before.
Now, wifi connects a little more consistently. Would resetting that way actually make a difference? Or is this just a random thing? Am I trying to see a logic where none exists?
How would a hard reset through the system settings be any different than one through recovery? Or, does each reset clear something else that got corrupted along the way?
My wifi still randomly cycles through scanning, connecting, disconnected, just as before. However, now the connection is actually made more quickly (under a minute when before it could take up to 15 minutes - or just never connect) and seems to remain connected for longer periods of time now.
Well, after searching and reading through 100s of similar issues one of the workarounds is to use a wifi widget or a WiFi Fixer App.
I am using a widget to control wifi and it along with any other random thing I might try can occasionally make my Tab connect to my Wifi network.

Persistence = Profit.
I think I have finally solved the broken wifi issue. Just to recap, the problem started after I did a backup with garyd9's CWM http://forum.xda-developers.com/showthread.php?t=1379532.
And as a last ditch effort I even tried toggling the wifi on/off with a widget as was suggested from other sources (Google is your friend), in addition to factory restores, or restoring from a CWM backup, etc. And that was not a reliable solution after all.
These are the steps I took.
Through stock recovery, I wiped data and cache, and did a factory restore, twice.
I ODINed back to stock, again.
Wiped data and cache and did a factory restore.
Wifi was still sluggish to connect, but finally I was able to load the update.
Then I wiped data and cache and did a factory restore again.
It has been 24 hours and I still have a strong wifi connection. If I power my Tab off and wait an hour or two, then reboot it connects immediately to wifi. If I toggle wifi on/off it still makes an immediate connection. YAY!
So, it seems that something got corrupted during the initial CWM backup and then persisted through many wipes and reinstalls.
UPDATE:
Still have working wifi!
I'm having the same problem now. I'm using latest CM9.
I was using Google Chrome just fine when suddenly Wifi disconnected for no apparent reason and it's now showing the same symptoms you described in the first post. I have formatted cache and cleared dalvik cache and it didn't work. Wiped everything and it didn't work. Reflashed CM9 and tried two different Wifi fix flashable ZIPs but I still got the problem. I'm wiping everything and reflashing CM9 once again.
Is someone else experiencing this?
I'm afraid to data wipe in stock recovery due to the brick bug reported (my tab uses one of the defective chips).
How is your Wifi holding up, VitaZora?
I hope persistance pays off.

My Tab also has the defective chip, but I didn't know that until AFTER I went through all those wipes and reinstalls.
But I can report that all is well and wifi is still working like a charm.

Ohhh I see...
I did wipe in HC stock recovery several times, but not in ICS stock recovery.
Have you wiped in ICS stock recovery? By selecting "Factory default" option from config menu or by manually going to recovery and selecting data wipe? Or both? Hahaha
Thank you for the reply!

Honestly, I can't remember. I know I flashed ICS twice as well as the CM9 version for our Tab.
I think the order for flashing from rooted HC was the following:
ICS, CM9, HC, HC, HC, ICS, HC.
In between each was either factory restore from the config menu or through recovery. Occasionally after flashing my device back to stock, it would go into a reboot loop and the only way to fix that was to enter recovery and wipe everything. But I reflashed so many times and tried wiping and factory restores multiple times as well, that I may have wiped ICS through recovery - in fact I am sure I did at least once.
Oh well, I guess I live dangerously.

Carefull! ICS stock recovery may brick you're tab. See this thread

WiFi troubles...

I installed CM 10.1 on a fresh storage (everything wiped. top to bottom) and everything is awesome so far until recently. I primarily use data but sometimes wifi for like netflix and stuff. I switched on wifi and watch for a while and am ready to go on to data and it says its on but I get no internet. WHA?? I have full LTE bars. I tested and every time I turned wifi on and off my data is shot. I tried going into recovery and wiping both caches and that'll temp fix it but as soon as I connect to wifi its done again.
Any known ways to fix this? Getting pretty iritating to go in, wipe, boot, every time I need data...

Wifi enabling impossible after Android L installation

Hi guys...
after installing the android L developer preview on my Nexus 5 i can't activate the wifi anymore...
back to stock...... unlock.... wipe dalvik and cache..... no luck....

Please help me.... i don't know what to try.....

I have the exact same problem. VERY frustrating. No idea what happened.
[Q] Stuck on WiFi Turning on
Hello,
I've seen this issue with various phones and various fixes... But I don't want to Hi-Jack anyone or anything. Anyway, I tried the dev build of "L" at one point... and my WiFi randomly stopped working. I thought "welp, it's a dev build... not gonna sweat it" and went back to stock 4.4.4... flashed back to factory, no dice. It seemed to turn on long enough during the setup process to "connect" but it disappeared when I rebooted to go to ART. Thought, welp, no experimental anything. Flashed back to factory, no WiFi. Not even during setup. Tried the various things I've seen around... obviously various factory resets, tried rooting and renaming wpa_supplicant.conf, flashed paranoid android because someone said that's the only thing that worked... it didn't. I do notice the kernel seems to be the same for PA and 4.4.4, so I could try another kernel, but have no idea which to try. After I put TWRP on, I cleared every cache, etc I could. Flashed back to stock after clearing system and no dice, tried running wifi fixer, tried installing macman... nothing. I did see someone say if the phone gets too hot, the WiFi chipset can come off, but the WiFi chip-set is the same as Bluetooth, and that's having no problems. I appreciate any suggestions, I really want this to work out. Otherwise I have a year with a phone with no WiFi... To kind of clarify (re-reading, I see I wasn't too clear about the actual problem), the WiFi toggle switch is set to "Off" and where your networks would display it shows "Turning on WiFi". This isn't just one network acting up, and this has been going on for a couple of weeks.
Edited to add: when I unlocked the bootloader today, the setup process showed me my networks but settings froze when I put the password in... so the hardware seems to be connected...

Bluetooth turns off an on by itself

Hello guys!
After the latest update my exynos S10e started to randomly turn BT off and than right back on. It also does it if I tap scan.
I already did: wipe cache partition, cleared cache of BT, turned battery ssving options off, messed with developer options like gabeldorsche, tried safe mode, I even factory resetted it, nothing helps, same behavior.
Bootloader version has changed, so no way to flash back old firmware (thank you samsung!).
I noticed this because the phone will lose connection to my car's BT after a couple of minutes. Interestingly, the connection is never lost during phone calls over BT, but the moment I hang up, the error message appears on my car's dash. And no it's definitely not the car. It worked with this phone and it still works perfectly with other phones.
Could this be hardware related? Phone is of course 1 month.out of warranty.
