Wifi/Bluetooth/Mobile Data dont work - Xperia Z2 Q&A, Help & Troubleshooting

Hello,
i just got the z2 from my uncle. He told me Wifi doesnt work anymore so he got a new phone.
After investigating i found out that Bluetooth doesnt work either. Both Options just wont "turn on". Reseting/Updating/Safemode didnt fix it so i it seems to be a hardwareissue(the phone has no scratches or anything).
I emailed with Sony Care, told them what i knew, they told me to send it in, told me its an hardwareissue which isnt covered by the warranty and i had to pay 15€ to get the phone back.
Today i opened the phone and everything seemed fine inside(antenna wasnt loose or anything). But now i also cant use Mobile Data anymore(calling works perfectly), im pretty sure it worked before tho. Im also not sure if GPS works(google maps wont open)
How do i go about fixing this?
I thought about getting those things: "Sony Xperia Z2 D6502 D6503 Antenne Antenna WiFi GPS", "Wifi Antenne Antenna Flex Kabel Koaxial Coaxial Signal" and "Z2 Replacement Wi-Fi Antenna Board PCB Original"
.. but that probably wont fix Bluetooth?! Is Bluetooth directly on the Mainboard and id have to replace that too?!
Thanks for your help

[Q] Changing Wifi / Bluetooth Cable

I believe that my wifi/bluetooth cable is broken, as I have no wifi or bluetooth signal since dropping my phone as reported in a previous post of mine. Can anybody advise me on the difficulty of undertaking this repair myself, does it involve complete disassembly of phone, any soldering etc. If this is the case I don't feel confident enough to do this so does anybody know of someone who does this sort of repair, I have found the cable on e bay for £7 and it looks like it has push on connectors ?
What exactly do you mean by the "WIFI and Bluetooth cable"? WIFI and Bluetooth are wireless, that is the entire point.

Internal Audio not working (hardware)

Hey guys, I have a hardware issue but first the background story
So my phone fell on concrete and the screen broke. I bought a digitizer and replaced it myself. After a month or so, I broke it again. I replaced it, but the unit I got was faulty, and I only got the replacement today.
I opened the phone again and replaced the digitizer, and it's working great!
however in the process I must have done something wrong since my audio/sound doesn't work anymore.
1)Loud speaker works just fine and the microphone works since I am able to talk to people and they hear me
2) When I plug in my earset, the sound works just fine on the earphone. The microphone switches over the earset's microphone and I can hear/talk just fine.
The only problem that I have is I can't hear anything if i put phone next to my ear :/ I opened again looked around, but didn't find anything obvious that might explain wha went wrong. Would anyone know where to look/what to test?
Cheers
anyone any idea please? D:
I haven't opened up my Mozart just yet but from my experience with HTC phones I would suggest checking the contacts of the speaker. They tend to have little springs on the speaker that come in contact with the mainboard and this is how the signal is transmitted. If these contacts are damaged then you will not hear anything.
With all the drops you may have damaged the speaker itself but I'm not sure of a way you could test that.
The problem i had was that I used my sony ericsson X8 headset and the sound came out funny, the thing that was cuasing it was the microphone. Try stock headset to see if it works. If it doesnt then you might want to get someone to check it or fix it. Up to you.

Has your internal speaker stopped working ? check the headphone jack...

My internal speaker & mic stopped working on my 6 week old Lumia 800- bluetooth & speaker phone was fine.. I soft & hard reset it but no joy.
took it to the Nokia service center that said they'd seen this before & they couldn't fix. It would have to be sent off for 10days or so.. Not impressed by this I told him to go jump...
On the way home I had an idea that this could be related to the headphone jack.. so re-plugged & unplugged headphones - and it was fixed !
clearly with certain 3.5mm plugs the jack doesn't always recognise that the plug is taken out & re-enable the internal speaker..
perhaps it was just mine (like it was new & a bit stiff ) or something to watch out for generally.
You should tell the Nokia shop guy to help anyone else with that problem
It's just yet another bug in the firmware. Sometimes if you unplug your headphones very slow or very fast it doesn't recognize it...
just like the iphone
That was the same issue with iphones for awhile. I used to have to "fix" that daily when I worked for at&t.
I think we should post all of these small, fixable issues and codes into one single thread titled "known problems and easy fixes" because nokia/ms websites blow at providing solutions. I had to use them multiple times this week because of a defective phone but they give you the way to do something if your phone was functional, not a way to fix something not working properly. It's a ****ing joke.

good idea - he said "nokia never tells you that sort of thing"
BTW it isn't firmware related.. I did a hard reset -so any state would have been wiped. The switch is part of the jack plug.

Hard reset doesn't affect your FW. I still think it is a bug in the drivers.
I picked up a secondhand lumia 800 yesterday everything was fine until I stuck my headphones in and before coming across this thread all I done to remedy the issue was reinsert my headphones 2/3 times and it sorted itself out I think there maybe a dodgy headphone switch in these phones although I have used other headphones since that and it hasn't repeated itself.

XSP-N1BT not chargin z3

Has anyone tried the Z3 in a Sony N1BT car stereo? I just installed my stereo yesterday and I can't get the magnetic charger in the cradle to charge. I thought it connected for a second and then it stopped. It's really hard to get it in the right spot. I called Sony and they are getting back to me. Not sure if my phone is the problem or if its just a really poor cradle.
Same problem

I have the same problem. When you change the application it works again, and sometimes it remains connected. I think that there is a software problem, the device(s) are ok.

I can't get the charger to work at all.
Mine works pretty well. Tricky to get it lined up with a case on it, but easy otherwise. And it charges very quickly.

Does anyone have an update on this? I have this head unit and and I just bought the new experia Z3. It connects to the magnet because I can feel the pull but it does not charge.

Exactly. In my case it's the same, it you want to try, when I switch to the radio, or phone, or Bluetooth audio, it charges 5 or 10 s, and stop charging (landscape view affected too). I don't know how notify Sony the problem, it's possible than a firmware update on the radio would resolve the problem.
Please, tell us every advance.
Excuse my bad English
I have the xsp-n1bt as well but i have no issues charging it. I dont use a case though because even with the tpu cruzerlite it didnt sit low enough to make contact and charge. You will feel a firm click and it will lock in place when the phone is connected to the magnetic port. With the case i would feel the magnet pull the connector on the radio up but not click and lock in.
At first i would have to play with it to get it to line up easily as the bottom of the phone (the side with the magnetic connector) has to be spaced out a little from the face of the radio.
I did add 2 (attached photo) of these low on the face of the radio and it made it much easier to effortlessly set the phone in the radio dock with one hand while driving. It keeps the phone from sitting too far back and not making connection.
I got it to work a couple times, Sony told me to clean the contacts. But it's still hard to get it in the right place
I have this issue. I can get it lined up and when turning the stereo on or off, it will charge for a few seconds then stop. If I leave the phone in place and turn the car on and off the behaviour is the same so obviously not a problem with the physical connection.
Annoying
Just to add more detail. I have found that if I change source (using App Remote) it will start charging for a second then stop. I can change between CD, Tuner, or a smartphone app and this behaviour will manifest.
Could it be something on the phone messing about with power? I'll experiment with my girlfriend's Z3 Compact and see if that is the same.
I found that if you place the phone to the right of the dock and slowly slide it to the middle and hear the click of the magnetic mechanism, it will start charging. It happens to work much better for me like that.
Tried my girlfriend's Z3 compact and that worked fine so it seems to be either the z3 model or something about my phone.
It's obviously not a problem with the positioning because it is charging intermittently (when changing source).
Does anyone work consistently? Put in on and if it starts charging, does it stay on?

Hello, I'm experiencing exactly the same problem with my Z3 (D6603)
- Charges for 5 seconds, then stops charging
- Pressing [SOURCE] on either the app remote or Head Unit allows it to charge again for 5 seconds, then stops charging on it's own.
Phoned up Sony support and they asked me to try things that were just written in the manual, which I already tried anyway. They then referred me to Xperia support, but not looking great there either.
They did confirm the Z3 is fully compatible.
Not sure where to try next!
EDIT: Just tried Xperia support. They said I need to test the magnetic charger on something else. Don't fancy buying a dock just to test it!
Hello everyone, its my first post here I hope it helps, sorry for my poor English.
No doubt my N1BT is working because my old Z2 still does the job. I'm having the same troubles charging and fitting the Z3 on place. After tricky precision I can manage to see the thunder icon but just for 10s like everyone else.
Once I got a message how says something like.... the phone consumes more power than the power provided by the charger. Or similar. And the thunder icon went off. I never got that message again, but I know is the same behaviour.
Once I made it work for a long time and all was fully functional changing the USB preferences. From MTP to MSC.
But while I was messing with my phone I decided to get a non branded sony stock version. All went fine and I started with a fresh system. I just installed the app remote and all google and sony updates. So I went to the car to fit it in the N1BT and it showed the thunder icon for 10s and off.
Now knowing that the USB preferences can solve it ...... No this time for me.
I tried another sony stock version for my country and same results.
The point where I get the thunder off is when THROW inside app remote changes to the car audio device. In the walkman app I can see a flick in the screen previous to get disconnected there's a small cut in the audio but keeps working from battery.
I have another error. Using the Z3 placed correctly on N1BT and obviously not charging I can use it running from the battery. If I press "Voice button on the N1BT" the app remote crash and the thunder icon is on again. If you don't press "accept " in the report window the app remote won´t restart and during all this time the phone charges. Once the Z3 restart the app remote the thunder icon goes off again.
I did another weird test. I have a Sony NFC BT sound bar and the Sony dock charger and also another magnet usb cord I bought. My test was to confirm the consumption, so I played audio to the sound bar while I was using GPS with with open aps in the background. I was connecting the normal USB for charge from wall socket an from PC, the sony dock charger and my magnetic cord. The Z3 did the job with any complain about energy.
About VOICE, every time I press it, I get a crash in app remote. And make me think about something related to Google voice and recognition. The error comes with the rounded window with a microphone but it never finish to complete the window or show the header with the supposed walkman or contact header on top. And this is changing form one app to another forget about searching for a song.
I hope we can find a solution, thank you for your time and patience.
Just to add some more findings. I put the phone in the stereo but powered completely off and it charged correctly. Clearly this is a software issue on the phone.

I wouldn't bother. You have the exact same problem as me and I have a desktop dock too which works fine so I very much doubt it's that.

Hi, I tried the MTP to MSC thing but it made no difference for me.
Can I assume from your changing roms that you are rooted? If so can you try using titanium backup to uninstall Throw? (Back it, and probably your rom, up first!)
I suspect that is the culprit but as a non-root user I can't do anything with it.

Good news: It's now working for me
Bad news: Not sure what bit made it work!
I'll list what I did so someone can perhaps replicate my results.
Z3 non-rooted - Android v4.4.4
1) Enabled Developer Options
- Enabled USB debugging
2) Connected Z3 in head unit whilst Z3 and Head Unit was OFF. Waited for it to start charging for about 30s.
-Turned on Z3 whilst connected.
3) Secured the Z3 into the Head Unit
Pressed THROW on the Z3 quick settings to connect rather than normal Bluetooth connect. Selected Sony Xperia Z3 (Sony Car Audio) from THROW options.
Now it works! The connection needs to be a bit better as it is quite loose, but I can work on that. I think the key for me was the THROW bit. I've disconnected/reconnected several times and it charges without disconnecting now.
Good luck - and let everyone know if it works for you or not.
So Bluetooth was off until you chose Throw?

That's correct, I turned off Bluetooth and then selected THROW. It then turns on Bluetooth for you anyway.
After that, it doesn't seem to matter if Bluetooth is on or off.
I'll give it a try later. Thanks

No service after replacing loudspeaker

Hi! I have Sony xperia m4 aqua and I recently changed the Loudspeaker because it had bad sound. When i installed the new speaker and turned the phone back on the sound problem was gone, but I don't have network. It says emergency calls only and I can't call anyone or be called by anyone. Searched a lot on the web but no luck so far. Tried to manually register network from settings-mobile networks-search networks but no result. I changed the sim card, no change. Restarted the phone many times.
Please help!
Maybe you forgot to connect antenna or some connector inside phone during replacing of earphone.?You will need to open again phone to inspect all connectors inside.

There's a a little progress. I opened it again and reatached the signal anthena cable on the downside(which you can reach after removing the loudspeaker). Maybe it got loosen after removing the bad loudspeaker. Turned the phone back on and it found network. But now there's another problem. The strength of the signal is not full and the Wi-Fi isn't there or it founds it for a little bit and then it's gone. So I'm wondering now if this little cable is the problem and should I try to change it.
P.S. Bulgarian too
Maybe you should check WiFi antenna if it's properly connected, inspect visual cable for cracks and etc. If WiFi work fine before changing of loudspeaker, then should work now if everything is good connected. Try to reconnect all connectors inside phone.

Yes it worked fine before changing the loudspeaker. I just opened it again it visually I don't see anything that isn't good connected. The only thing i can think of is maybe this cable
Sony Xperia M4 Aqua Signal Antenna Repair Guide - which is on youtube
could be damaged, but i'm not sure and don't know how could've damaged it. I don't know. If you like i can take a pic and upload it.
Yes, take photo to see if I can help or somebody else with more experience .

Here it is (after removed battery and loudspeaker)
You should inspect both coaxial cables connected at left and right. Maybe there are not good connected, try to reseat both of them on both sides to see if this will helps. Use magnify lens (лупа) to inspect cables and connectors more precisely.

ok
This is a English based forum. Tiny white cable is for antenna. Check both cable and connectors.

Did she drop the phone by any chance? Or has she taken it into the water? No matter how much Sony claim their phones to be waterproof, they're never 100% waterproof especially when they get older (the heat from charging/general use loosens the glue/seals a bit).

Is your loud speaker working?
I believe the speaker is built into the same unit as the mic. If the loudspeaker isn't working either, then it's an issue with the cable. If your mic is dead and loud speaker is working, then it's a lot harder as that board is quite a pain to replace.
