[Q] Sony Xperia ZR Wifi & Bluetooth functionality Disabled

Hi,
Brought the Sony Xperia ZR a few months ago.
It was giving problem with Bluetooth right from the beginning but haven't bothered about it as I used it rarely.
The wifi initially was working fine, but few days ago it just refuse to turn ON.
When tried to turn ON the wifi using ON/OFF slider it hangs up showing pale blue color & comes back to OFF state.
The exact same thing happens to the Bluetooth slider as well. (See attached screenshot)
Searched in some forums & see many people faced similar problems with their device as well.
However no one have given proper solution for it.
Tried everything from Re-boot, Factory Reset & Phone repair option using PC Comparison...None have worked to resolve the problem.
Some people say it is hardware issue & needs replacement of device however others say they had same problem come back even in replaced phone as well.
There was something mentioned about region code reset mentioned here
android.kul.is/2013/09/sony-xperia-zr-wifi-problem.html
but it looks unverified.
PLEASE provide solution for this issue.
Thanks in Advance.

There are other people who have similar issues, including me. Symptoms vary, but ultimately we are unable to use wifi and BT.
I have an additional issue with no USB connection to PC

Will downgrading work?

One of my friend is using the same phone for over a year now & have not upgraded to Kitkat & never had any issue.
Do you think downgrading the phone from Kitkat to JelllyBean will resolve this?

Don't know. People say that things work igf you poke the phone at right places. (is the ZR a human to get excited when fingered right?)
I had some success doing it and wifi worked for a few hours. This is obviously a hardware issue.

It's a hardware fault. There's a flex cable attached to the motherboard that comes loose and this leads to bluetooth and WIFI problems. Bluetooth seems to be the thing that goes first which is what you've seen people complaining about.
You can fix (at least temporarily) by pushing the flex cable in.
1. turn off phone
2. take out battery
3. carefully peel up black adhesive tape that was underneath battery. You only need to peel up top right corner near battery connection.
4. Underneath you'll see flex cable going into main body toward camera.
5. Carefully push this in or get something very thin and flat and carefully slide in under flex cable toward camera.
6. Reassemble and see if it worked.
I haven't had bluetooth in ages. Then my 2.4 WIFI dropped out like yours and I could only use 5G WIFI. FM radio also stopped working. I looked at the disassembly manual and worked out it must be that flex cable as pushing in the body below the flash fixes bluetooth/WIFI/Radio temporarily. I tried pushing flex cable in and voila FM Radio and WIFI started working. A bit more wriggling and bluetooth came back on.
However, it seems to keep coming loose again and so I'm going to have a go disassembling fully soon to see if I can make a permanent fix. Just waiting on replacement glue strips from China for underneath the screen.
It's just a poor quality connector that comes loose. It would be an easy fix if you could access the insides but because it's waterproof the only way to get in is removing screen etc.

Ok. Bad news sorry.
I opened up the phone and had a go reconnecting the flex cable. It didn't fix Bluetooth.
It did fix the 2.4g wifi but only temporarily again.
I think it must be a problem on the motherboard.
Sorry. I really thought I'd figured it out.

sad
:crying::crying:
I felt light of hope but all in vain. I knew that it has a motherboard problem that cant be fixed. Sometimes the phone gets restarted several times it self to activate 2.4 Ghz wifi. It is mother board problem. now the only way of using wifi is either purchasing 5GHz wifi router or creating 5Ghz wifi hotspot through pc or any andorid cellphone.

you should try flashing last version of 4.3 n see if BT n WiFi work as u want

Already tried. It's a hardware problem.

Actually I have another idea. I've noticed that the second Mic doesn't work very well. There's two circuit boards inside, one with Mic and other stuff on it and then the main motherboard. They have two contact points that are just touch contacts, not hard connections. There's shiny metallic squares that make contact. I wonder if they're the issue? It would explain why pressing in that place under the flash activates Bluetooth. However when I looked at them when open I couldn't figure out a way to press them together any closer. I'm going to have another go later today.

In saying that, they're nowhere near the Bluetooth antenna. The Bluetooth antenna is actually under the top left corner of the phone when looking from battery side. You can access it by increasing the torx screw and prying up the waterproof cover. The cover has some glue stuff underneath to keep waterproof.

Removing not increasing torx. Stupid autocorrect.

Ummm I just flashed stock 4.2 and wifi is fine. 4.3 wifi is dead. 4.4 is dead. What did they change at 4.3?
Bluetooth still not working on 4.2.

Oh I don't know. 2.4 now working fine after flashing 4.4 again.
It's too unpredictable. However, Bluetooth is definitely dead on mine.

wifi sometimes gets connected for few hours. After that it again dies

That is work for me
Same problem with me bro.Then i will flash my phone with flashtools and then its works fine

Ok I've figured out the Bluetooth
Just like the WiFi the problem is a poor connection to the bottom board which is free to float around. It was an Idiot who designed this connection, bottom board should have been sitting on plastic shelf or spacers.
I've attached two pictures showing the pin 1 that needs to contact the conductive plate 2.
I fixed by placing small stacks of the screen adhesive under the four corners of the floating bottom board 2.
This forces it up to make a better connection with top board 1.
Obviously you need to remove screen to do this.
However, it may be possible to fix by jamming a small rigid piece of plastic in the top of micro usb slot above the jack as that's the corner of top board that needs to be forced down.
Another alternative maybe to open the corner from the back and try and force the bottom board against the top. There's two screws and some prying to do there.
Also, in addition to the adhesive spacers, I suggest placing some copper tape on the conductive square (2) to improve reliability of the connection. Similarly with the wifi squares which are on opposite side and corner of floating bottom board (2) to the bluetooth square.
My Bluetooth and wifi are now fixed. Yay.

[Q] Gyroscope not working.

I got my phone on Wednesday (4/8/15) and everything was perfect with the phone nut as of last night (4/9/15) noticed that camera was not rotating and it was kept on landscape, and also applications like youtube would not automatically rotate from portrait to landscape. I verified the screen rotation setting and it was on, did a factory reset and nothing. Called Samsung and no help there they don't know what the problem is. Went to an AT&T store and they could not find the root of the problem, so they are trying to get me a new phone. But while I wait I would like to see if there is a solution because if I can solve it (with help) before I get the new one I can cancel that order. Any one with same issue or knowledge of how to get it fix? please help

Same here
I had it rotate maybe once right when I got it and then it stopped and I have not been able to get the phone to rotate at all, photo, video, web browsing nothing. I am about to do a factory reset to pray and see if that clears it up.... if not its back to AT&T for me as well.
I installed a level app and it at least appears that the accelerometer is registering motion and position, but I am not sure if its reporting right (angles dont really look like the angle they should be.) So I could be faulty hardware/firmware.

it looks like the gyroscope maxes at 30 degree's when the phone is stood on end (which should be 90). Wonder if this is a software/firmware bug, and I am going to assume 30 degrees inst enough to cause the phone to rotate and change position.

I have the exact same issue. 64gb sapphire black edge.
By any chance do you have a wireless charger?

don't have a wireless charger yet. should be getting it next week. but tried the wireless changing at an AT&T store and it worked well. as of the screen issue have to wait 5 business days to get a new phone from the store since neither AT&T or Samsung can figure out the problem. and I am noticing more and more people with same issue here and other forums

I'm giving it a few days for some sort of solution to pop up. If nothing I'm jumping on the return wagon as well. :/

Had the same issue as well. I went to best buy to get a new phone.
I think it might have something to do with the fast charger as it might have fired the gyroscope, because my rotate worked fine till I took it off the wireless charge and plugged into the faster charger.
Best bet would be to call up Samsung and ask them if they there is a issue with this and hopefully they will send out an update (If possible) to fix the gyroscope.

Software issue
I just spoke on the phone with Samsung. This is a known issue and it is NOT a broken gyroscope. It is a software issue and they are working on a fix.

Samsung called too a few hours ago. They are checking on the issue and also there will be an update soon.

I got a verizon S6 edge and it also has the same issue.
I got the black one with 64 gigs and it has the same problem verizon gave me brand new phone as it is under 14 days replacement. I also found that if your mobile is not fast charging just push the usb cable gently into the charger. If you want to use slow charging you can pull it out slightly. There are two modes in the charger.

S Pen not working

After I accidentally inserted the S Pen backwards, but later on managed to remove it successfully, the S Pen is not working.
It can still be detected, ie triggering Air Command or screen off memo, when I was removing it whilst it was stuck, but after it was removed it does not trigger the Air Command, and the worst part is it does not interact with the phone in anyway, not even as a stylus. :crying:
I only got it for a few days, and really hope you guys can help me solve this issue. If not I will send it for repairs and hopefully get it fixed for free or low cost.

Hi,
I have a similar problem after accitaly insert in wrong way.
The S pen work, but there is no detection anymore.
I had to remove every detection in settings, but I still have some notification about S pen removed.
(you can trigfer air commands by double click S pen bouton)
I would like to know if someone did repaire the sensor?

There is a switch inside the phone which you have broken by yanking out the pen after it was inserted the wrong way. There are videos on YouTube that explain it in detail.

Yes.
I would like to know if someone did repaire this switch, in a Samsung repair station?

spen working method
You can actually use the spen by going into settings, spen, and than turn off S pen power saver mode

My spen first began to get less and less responsive, i.e. I had to push hard for it to interact with the screen, and now it completely stopped interacting with the screen.
no idea dafuc is going on!

My phone won't detect my pen. It works though

I got mine stuck, removed it by inserting a bit of paper and now it doesn't work and it doesn't detect lol. fail.

First try to.change you tip with a spare one from the box. If the problem remains do a software reset . If none of this solve your problem then search with google for spen sensitivity. There is a metod to fix this problem.

Fast Charging Only Works Wirelessly

After searching related posts, I still haven't found a solution to my problem.
- I have tried several 2.0 quick chargers and cables that all previously provided fast charging for my Note 5, but I'm still only getting regular cable charging.
- Tried unplugging and plugging immediately
- Tried soft reset
- Tried wiping cache
I don't know why fast charging suddenly stopped working. Wireless fast charging still works 100% of the time. Any suggestions?

Bump. Need help please.

Try using Odin to reflash the entire firmware. If this doesn't help then you will have to have Samsung send you another phone and they will as long as it's not over a year. You can download the firmware from sammobile and other places and then use Odin on Windows to flash but be sure to enable oem unlock in developer settings.
Before trying all of this toggle the fast charge off and back on again and reboot then see if it works

Thanks for the reply. The on/off toggle and restart didn't work.
There is something strange I notice when plugging in a charger sometimes. I get the notification for USB options. I feel like the fact that it's giving me the option to choose a media device, means that my phone is not recognizing the cable as a charging cable. Attached image.
Changing it to "charging" does not make a difference.

It's supposed to give you those options mine does that too. Try doing a full firmware reinstall and then if that doesn't work you really will have to ask Samsung for a replacement.

Well if its rooted .. Samsung won't. But you need to ask samsung for another charger.

Interesting that I see this post...I had exactly the same problem with a friends Note 5 ( SM-N920W8 ) he bought from a guy he found online met in person, and had the exact same issue.
I thought it might be the rapid charger, but it wasn't that at all.
He ended up selling that Note 5, and bought a brand spanking new sealed 920W8, and it now works perfectly fine.
I should also note that his N5 had a nice mark on the lower left side, which to me, it definitely has been dropped, I think it has something to do with it.
Hope this helps.

Well I tried reflashing the stock firmware with no luck. And I ultimately did a full restore, but that didn't work either. Can't take it to Samsung because Knox is tripped.
It must be a hardware issue at this point. Maybe the charging port on the phone needs to be replaced?

I'm having this issue too.. tried the same things you did.. I did called Samsung and it asked me to make a factory reset. But I don't want to do that... Mine is not rooted and I don't want to restore my apps manually... Did you tried factory reset?
I'm googling for 3 days and I guess it's a software issue... I use several usb chargers, I guess you too... and one of the times it detected the charger as a computer... I think it messed up everything....
I bought mine in Hong Kong so no warranty in my country... don't know what to do, but if you could try the factory reset I'll be interested to know if it worked.
EDITED: only now I saw you did the factory reset... sad it didn't work.... I head of people that used air machine to clean the micro usb slot.... they had some luck.. I didnt...

Samsung really isn't going to give a crap that Knox is tripped because they even send "certified replacements" with Knox tripped.

Did you happen to drop your phone ever?! Like even a slight drop? Did you get any moisture in the charging port? Because Samsung acknowledged that, that's a problem..

Slight drop. Yes... for sure... I use a plastic cover and glass protector, but I already let it fall from my pocket once or twice... It does not have a single mark on the device thought...
Things I suspect more, once I download a windows exe program that used ADB to debloat the device... did not function but I had to reset the device.... and as I said, I use multiple chargers, even a chinese powerpack cover that once was detected as a PC... very strange....
The fast charging is not a must for me... as I charge it during the night, but it sure is a hell of help when I have to use a lot of camera or GPS....

Factory reset didn't work. Cleaning the port with alcohol, cutip/small object, and canned air didn't work. I have dropped the phone, but nothing significant. Everyone has (probably). Should be no water damage.
I also used to think it was something software related. As you said xnes, I also suddenly started getting the notification for USB options when plugging a cable in (thinks it's a PC). I didn't used to get that before when fast charging worked properly. Since you're experiencing this too, I'm going back to a possible software issue. I never connected and pushed anything to my phone via ADB though.
I was gonna just replace the charging port, but after looking at the DIY video, I'm not about to remove the screen (and potentially breaking it) to replace this port, which may or may not even fix it.
Hmmm.. I don't know.

Use your own firmware though.. if this doesn't work then it's not a software issue.

No sir, your Knox will be fine just follow the instructions and use the correct firmware for your phone.

Can you believe this? I've been in contact with Samsung support and they've confirmed that my phone is under warranty. So I send the phone out to them, and they send it back saying:
"We have performed a thorough examination of your device, and it has been determined that the unit is beyond economical repair. The unrepaired device has been returned to you."
So much for having warranty huh? So furious with Samsung on this. Won't even fix their faulty charger! Now I have to restore my phone again for the 14725625th time.

What is happening to my Nexus 6, is there aniway to fix it? [Water Damage]

My nexus 6 falled from my hand to a small puddle of rainwater like for 15-25 seconds, i picked off it then i saw that all works normally i dried it with my shirt and, saved it in to my pocket after a few minutes i wanted to do a phone call but saw that the screen were all black and showing some lines i went to my house and tried some times to turn it on but anything worked, then i left it in a container with rice for 24 hours today i tried to turn it on but it is not working , when i push the On button it just show some lines with a very light green/yellow background and the green notification Led is turned on. What i can do? what is happening to my nexus?i need to buy a new screen? is there another way to save my phone?
Any suggestion?
Hope someone could help me
i had taken some photos but i can't post it due to the restrictions of a minimum of 10 post in the forum but there is an album with two photos of the nexus in my profile.

It could be the screen. Mainboard is also a possibility here. Someone is going to have to look at it and see what's wrong.

Thank you so much for answering, by the way i have posted some images of the phone in an album in my profile.

Rule of thumb with possible water damage is NOT to turn the phone on until it is dry. By turning on the Nexus, you guaranteed yourself a repair bill at best, or having to purchase a new phone at worst. Looking at the pics in your profile, your problem is on the motherboard. Someone will have to take the device apart and look at it to be sure, but you're likely looking at a motherboard replacement.
If you have a warranty, try using it.

[UPDATE] First i opened the nexus and disconected the battery from the phone dried competely with a towel then i left the phone for half an hour in a warm place then i dried it a little more with a heat gun , after that i left it in a bag of rice for two days and today i taked out the nexus, conected it to the charger then the green led started to turn on again, left it like for 4 minutes charging and then the nexus suddenly turned on! with all functioning correctly the screen the sim wifi all! , i was so happy and lifted up the smartphone to look at it but then the screen started to show some blurred lines and blue colors and a little bit distorsioned graphic interface in the screen but with all elements in screen.
Now i turned off the nexus
The problem could be the flexor of the screen?
because when i removed the back cover of the nexus with a guitar pick maybe i damaged the flexor or something like that
What i should do?

As I've said repeatedly, get someone to look at it. With the symptoms you describe, there could be multiple causes, and only a technician or repair center can determine the actual cause.

Don't get angry
It was the flexor , All works nice but the flash does not work
I will try to repair it

I'm not angry, but I don't like having to repeat myself. Anyway, let us know if you get the flash fixed.
