[Q] bluetooth & wifi not turned on !! help me

Hello. Bluetooth and wifi notr work on my galaxy s4! I tried to reflash with odin the latest rom available (XXUBMGA ITV) but nothing. I tried the solution in various forums but have not found anything. IMHO is definitely a software problem because before you restart the phone everything worked perfectly. Someone can help me?:crying:

Did you do a data factory reset after flashing the stock rom?

Then it may probably be a hardware problem and you should take it in for repair.

There is not much more you can do than reflashing the stock rom and resetting the phone, turn it in again for repair because the problems with BT and wifi are still there bro. They may have to replace the motherboard.

It is possible that the failure is determined by the coupling with a Polar heart rate monitor? because it is the last thing I did. However, until you restart the phone bluetooth and wifi worked perfectly, it is possible that a hardware problem?

You could try uncoupling it, reboot and see if it works well then. Is this heart monitor coupled continiously (by bluetooth?)

the problem is that I can no longer activate the bluetooth. continues to flash on and off. riflashando possible that the stock rom (PDA + Phone + CSC) does not'll switch on drivers bluetooth?

Take it in for repair bro, it should not be your problem and it should be fixed correctly. If it is repaired and you pick up the phone bring a bluetooth headset with you to check wether the bluetooth issue is resolved. I never had any issues with wifi and bluetooth.

I checked and I am certain that Samsung did not change the form of wifi nor bluetooth (mac adress are identical), then the solution is software. I have not tried to reflash a rom older. could solve? there is some secret code to reactivate the bluetooth driver?Thanks

I deleted the data of the service Google Services Framework and did a reboot and bluetooth and wifi started working and turned on. at the second reboot did not work yet is not a hardware problem..but what can it be?

@DexterJack:
Have you found a solution?
I had the same problem starting on August 15th with Bluetooth suddenly stopping and forcing another app to stop.
(I'm on stock rom i9505XXUBMGA).
Since then the phone is trying to switch Bluetooth on/off every 30 sec. (10 sec. "trying on" (dark green in the notification menu), 30 sec. off (grey)).
WLAN is also not working anymore. WLAN connects for ca. 10-30 seconds and then switches itself off.
LTE works.
A few times over a period of several hours the device reboots randomly (but without fixing the problem afterwards).
I have removed the battery for 8 hours, but that and all other things I tried did not help.
Then, after using LTE for ca. an hour, I saw that Bluetooth switched on!
I could then normally activate WLAN and everything worked like before (I have the S4 since end of April).
WLAN and also (already paired) Bluetooth connections worked fine again.
This was the situation since yesterday (10 days of heavy use without any issue).
Yesterday I opened the Bluetooth settings menu to pair new loudspeakers.
Within seconds the Bluetooth and WLAN problem reappeared.
Since 24h the same problem is back.
Could it be related to firmware/radio UBMGA?
(I had no issues with UBMF8 and the other stock firmwares before)

same here ;(
have u already tried to flash stock with repartition?
are u both on pure stocks? (red somwhere custom binary/system mark in bootloader may cause such problems)

@bofff:
No, I have not flashed any (stock/custom) ROM yet and no repartitioning.
I read in another forum that flashing different ROMs didn't help.
This user tried three different ROMs, two different kernels, full wipe etc. (I haven't read anything about repartitioning).
He finally flashed it back to stock and sent it in for repair.
Samsung didn't find anything, but Bluetooth and WLAN worked again.
One day later the same problem happened again.
A new factory reset didn't help.

my s4 is still repaired by Samsung..

Possible Fix
I had the same problem (also on MGA) and managed to solve it. The trick was to flash an older firmware. But it didn't work after the first flash.
In combination with the WiFi and Bluetooth problem i had a notification telling me that a program tried to do something unsafe and that i had to reboot my phone to fix.
Here is what i did :
1) Complete wipe of the phone
2) Flash older firmware with odin (I used this one LUX-I9505XXUBMEA)
3) factory reset (at this point still no WiFi and Bt)
4) flash same firmware again.
After this my phone worked normal again.
But I have a second problem that came right after flashing this MGA rom. It seems like my battery is broken. Sometimes my phone switches of with still 30% left. I need to plug him in to the wall to boot the phone.
Not sure if this has anything to do with flashing MGA firmware, but at least my Bluetooth and WiFi are working fine now.

I read a report about some faulty code (something about a camera daemon) that was keeping the camera in memory after it was no longer needed in KitKat builds....apparently Google's working on a fix...
This could be it. Or maybe your problem is different...if you're rooted, you can try wiping cache, dalvik, and battery stats....
(<---Remember to Thank me if this helps :good

are you on Wifi ? Saw your wifi always ON, but no wifi icon on your status bar.
if you are not on wifi, but your wifi always on, try to off "always scan" in the advanced wifi setting.
Other than that, you can try to off your google location. go to account, google, location. OFF it.
if still not work, since you are on stock non rooted, try to do factory reset, go to recovery (vol up + home + power), and do wipe from there.

Hi,
I do not really understand "wipe" ... sorry I am not expert in it. My apologies.

Lag and Performance issues.

Hello, I have an old NOTE 4, ive had it since release date but ive started to get issues, its only happened in the past month, ill explain every single thing that is happening below.
1. When switching from apps sometimes it will take so long to open the app and during this time i literally cannot do anything, cannot open the app drawer to force close apps, cannot slide from the top to see the notification bar, after a 30seconds it will lock the phone screen (The time i have the timeout on i suppose) and then i cannot even open the lock screen nothing literally works, maybe after a minute or two it will finally let me. Sometimes a battery pull is needed.
2. When typing it will lag and do the same thing above with the freezing, and even during these processes once the screen goes black (sometimes i can still see the notification bar) the phone will completely restart itself on its own.
3. Just other general slow downs.
Here are the steps I have done to try and solve it (still no luck)
1. Wipe Cache and Dalvik Cache through TWRP.
2. Uninstalled apps and cleared out files
3. Installed an antivirus software and run tests.
4. Formatted SD Card (Removed it as well)
5. Completely formatted the whole phone (Every single bit of data (selected all options in TWRP except SD Card) so it says no OS has been installed.
6. Installed the latest stock firmware through samsung kies.
All of the issues are still happening, whether i root it or not, it will do the same. Im out of ideas and have no idea what to do. Its becoming so annoying having to constantly pull out the battery and what not.

Hmm I don't know what to say as you have already done a complete wipe! But I don't understand how you flashed the firmware through Kies though! Doesn't than need an already working phone with a ROM already installed? Don't know, have not used it for long time.
Just try to flash the stock firmware via Odin once, see if that makes any difference, after a complete wipe of course. And please don't use any anti virus, that's not needed at all.

Buy a new phone! ?

Well it never used to do this so I can't see it being touchwiz, I just think the phone is nackered

Sounds like something is seriously off with your phone and that it needs to be repaired.

Did your baseband somehow change. That will cause super serious lag issues and it will not get any better until you reflash modem. Also maybe try a different kernel

OOS 3.0.2 Home button and fingerprint scanner is not working

My phone was working great after updated to OOS 3.0.2 yesterday.
But today my home button and fingerprint scanner is not working.
At 1st it was showing the " Fingerprint hardware not available" error message, but after restarting the phone, even my home button is not working.
The option to add/delete fingerprint in the "Security & Fingerprint" setting is gone.
And the test for fingerprint and home button using *#808# failed.
The test for fingerprint shows a message " The application cannot reach the android service for the sensor".
Ways I had tried so far :
1. Wipe cache (failed)
2. Wipe data and cache (failed)
3. Wipe data and cache + Reflashing the OOS 3.0.2 (failed)
Any suggestion on how to fix it? Thankyou. :crying:

Hi I'am having the same problem as your are. Flash from 2.2.1 and still fps not working. I hope someone can address our issue

Hi Again!
You MAy try the work around I did today:
1. Wipe Data and Cache
2. Install OOS 2.2.1-2
3. Check if fingerprint scanner is working if not flash OOS 3.0 Beta 2
4. Activate on screen button and wait for OTA notification
5. Download and install OTA update to OOS 3.0.2
6. Setup up fingerprint scanner, use password instead of other secuirty lock options.
That procedure work for me. Hope this fix your case.
Thanks!

Currently submitted a ticket about the problem to oneplus, they mentioned in the reply that they will assist me with a Remote Session to try and fix the phone. If the problem is still there after this, might as well as try to flash a custom ROM. Thank you !

I'm in the same position as you. My phone had been great for the past 6 months. ✌ days the fingerprint sensor told me ?
I've tried going back to stock 2.2.1 and stock recovery; I've tried draining the battery but still no go for me.

done almost everything flashed Oos 2.2.1 ,CM,PA 3.0 beta Oos,3.0.2 Oos but it still says fingerprint cant reach hardware and blah blah

If all software fixes fail, it's hardware.
First try RMA.
Still want a dirty fix try this.
Go to the near electronic store and grab some contact cleaner and spray it over the FP sensor leave it until it dries, repeat a couple of times and reboot.
Has worked for me couple of times in the last week but it fail again in couple of days.

Hi, I got the same problem, did anything here worked?

I'll repeat this over and over again, its a hardware fault. Get it sent out for repair.

I am facing the same problem dont knw what to do tried everything but when the sensor start to work the home button continuously starts to get pressed it self

It's a production fault, just like the touch screen on the Oneplus One.

what worked for me: start in safe mode
go to settings > apps > system: search for fingerprint service
tap storage > clear data + cache + force stop
reboot

Odd data connectivity issue, only on custom LP and MM ROMs.

In the past week or so, I suddenly have a hellova time getting data connection on certain ROMs. At first, all was working normally, no matter which Android version I was running. No idea what changed.
Here's what's happening: Whether I restore a backup or do a clean flash, all the Lollipop and Marshmallow ROMs I've tried give me very intermittent data connection. When I boot up, I'll see the signal bars as usual, but there's a small exclamation mark at the end of the bars and it won't connect to 3G or LTE. I've tried all available APN fixes I could find, and it makes no difference. Sometimes data will work upon booting (not very often, though) but it'll completely go away if I toggle Airplane mode or reboot again. If I go into network settings and manually switch it to 1X mode, I'll get a 1X connection, but switching to Global, 3G or LTE preferred just gives me total data loss again.
On a whim last night, I took out my UICC card and I suddenly had reliable 3G. As soon as I put the UICC back in, it was giving me the same problems again. I was on MK5 modem, but switched back to stock OK3 and it didn't change. I've ODIN'd back to stock and the issue still presented after restoring or flashing.
This issue isn't showing up at all with KK ROMs, which is probably the most confusing part. I'm using a Boost L720T, if that helps at all. Any ideas?

I actually tried WickedX yesterday. Even the barebones version was a good bit more bloated than I like. Personal preference aside, I still had the same data issue with your ROM, so I reverted back to SlimKat.

Decided to go with the newer stock modem, even though MK5 seems to give slightly better connection. Right now, it says L720TVPUCOK3
