Anyone out there with this issue? I have multiple wifi network profiles on my Tab for Home (2) and at Work (1). Out of these 3 profiles , 1 profile from home (wpa) and the other from work (802.1x EAP) will reboot the GT each time i turn on the wifi. The only way to stop this from happening is to remove these profiles. Not very productive but thats the only way to get rid of the booting. Anyone facing this issue ?

It just happened to me too. Got the Android panic screen.
Mine just reboots wo any panic icon
Re-flash with the latest firmware.
Dear zyborg, i am a complete noob in this area coming from the WM platform. Can u point me to the link on how to flash a GT rom? B4 i take the step to do that , i would like to try hard resetting first...which will totally remove the rooting and not just the privacy - return to factory default? Is there such a thing like that for android devices? TQ in advance
Reflashed at Samsung centre. Issue stil there.

Take it back as it sounds defective..
I have the same problem. Did you get it solved or is it a hardware error?
I couldnt prove it to Samsung when i was at the sevice centre because the reboot didnt hapen at their wifi router. I came to a conclusion that the problem only arises on certain profiles and certain wifi routers. Compatibility issues? So far my dlink router and corporate router, cisco is giving me this issue. I had another 7 inch tablet, CSL and i never faced such issues with the same settings

I found out that the reboot does not occur when i only have one wlan profile configured.
So i think it is an softwarebug. Do you agree?
Thanks!
Yes. I agree. Looks like its only u and me for the time being. Btw my rom is dxjj1. What is yours?

As i have baught my tab at Amazon, i have the possibility to change it on warranty for a new one. Maybe i will do this on next weekend.
I will keep you informed about my encounters.
Thanks lulatsch99. Would really like to know the outcome from yr side. Tomorrow i am getting a help from samsung tech guy to meet me at my office to test out his tab. Will try to simulate the same profiles to see if his machine boots too.

Hi,
today i got my brand new exange tab from Amazon. I tested it without installing any Apps.
The same reboot problem appeared. As soon as i had configured more than 1 wlan profile, the tab rebooted after switching off and on wlan. The same happens when i activate and deactivate the Offline modus.
This even happened when i had one profile for real and one dummy profile configured. After the reboot the wireless lan connection works fine until switching off and on wlan.
Both profiles i configured with wpa2 psk.
Now i really think this is a software/driver bug. Most of the tab users seam to have only one wlan profile, otherwise more people would have this problem.
Oh, i also contacted the german Samsung support. They never heard of this problem.
Please let me now if you got better results with or from the tech guy.
The tech guy from Samsung couldnt make it. Next schedule is next week. I am not too hopeful now since ur scenarrio proved its not hw related. Maybe Samsung in Germany and Malaysia should talk to each other. Thats provided the log down our issues in the database. Will update you once i get to test their units. I also tested that this problem will exist if one profile is on wpa while the other is on 802.x

I have the same issue. The tab also reboot eventhough I have only 1 wifi profile configured. I try "factory default" several times but issue still exist even no any app installed at all.
my version is also P1000DXJJ1.
After phone consult with local Samsung call center, they have never seen this problem.

Either Samsung is trying to cover up till the next major update or not enough ppl is having this problem to make it a major issue. May I know which country you are from ? I am from Malaysia. If we at the same location, then maybe we can go there together and make a point.
Ii finally met up with the Samsung tech guy today. Same issue with his TAB. So I guess its a bug with the software. He will feedback to Samsung and I guess all we can do is wait till the next official ROM to see if they have solved it. I will try the DXJK5 ROM later this week to see if the problem appears there.

Hi cmloo, I am from Thailand. I have posed on some thailand's user webbroad but no one has this issue. I recently not have this issue for 1 week also for normal use which not repeatly turning on/off wifi.
Thank you for your update.
@cmloo
I fully agree! Thanks for the upgrade!
Hi,
let me thank you for all the help you may give me.
The problem is i get stuck on obtaining ip address or the cell doesn't even try to connect automatically so i have to manually start the wifi connection to the network after turning on wifi.
The problem of my SGS not connecting automatically is rare, the first is not, it's actually quite often.
I looked through all the guides and sugestions but i couldn't find any permanent solution for this problem.
Note: I've used the AllShare app but sometimes even that doesn't work.
Thank you for all help
The same problem kept happening with me. Some of the fixes which I tried were
Change channel on router - didnt work for me
Use the allshare app first - worked
Set up a static ip in advanced settings - almost always worked
But I have found that I didnt have this problem with other routers, only mine, maybe because of a power problem with the router.
Many of baffling errors are usually caused by bad input power to devices.
Hope it helps
Thanks for the reply, the problem is that i use it alot on my university, where i can't do any changes to their router (or use static IP).
Also the AllShare app is indeed a fix, but only if used every time i think. I'll do some more testing, this problem is really annoying and that's a shame because it complicates the use of most of the smartphone capabilities.
So if anyone else as another solution i would be glad to hear it.
Also i'm on stock rom installed by my operator Vodafone (had the same problem on JPY).
Edit: After a very quick test, it seems that using Allshare once does work, but i had the impression that sometimes it would be needed more than once (even without rebooting). TY for the tip.
Update:
After some more tests i came to the conclusion that at home i need to use AllShare every time i want to connect to my network.
This seems to be a problem affecting several users of SGS, does anyone know the answer to this problem? Or at least an app that minimizes it?
It's quite bad and very frustrating. Thanks, for any and all help.
I had the same problem with stock Android 2.2.1 on 3 phones all Galaxy S. Dropping the packages on voip calling, internet was slow most of the time. I use a linksys wrt54g with dd-wrt, I never had problems with any other devices.
My problem was solved when I installed GingerReal. Also on Miui I didn't had any problems with the wifi connection.
Maybe is just the stock driver incompatibility with some devices.
Thanks for the reply,
I've only had bad experiences with flashing, last time i did everytime right and Odin just hanged, i almost had a serious problem in my hands.
Since this is probably the first and last good phone i'll ever have, i would really like not to kill it (also some people in my family would be very disappointed, it was a gift).
So any workaround? Sorry i'm so insistent but i think that are a lot more people interested in this. TY.
Hello XDA guys. Your webpage is awesome.
I have a problem witn my Z3C (5833) for a month now and I have tried many things with no success. I hope you can help.
My phone was updated to Lollipop not long ago (May - June to 5.0.2) and in one moment (I cannot tell exactly when) the GPS sensor stopped working. The Wifi and Mobile location work, however the GPS is dead. Phone not unlocked or rooted. Original Stock ROM.
I go to the about phone - Diagnostics and test the GPS.. and it stays as "GPS is starting ... the GPS couldnt be started". When I download GPS test apps, they dont detect a single sattelite. I also tried the *#*#7378423#*#** GPS diagnostics, "purged assistance data", and it keeps on "waiting for location update" eternally
Because of this I wrote to Sony and they answered asking me to do a phone repair from Sony PC Companion. I did the phone repair and the problem was not solved.
Because of this I thought .. hey, maybe Lollipop is the problem. So I unlocked the bootloader and downloaded Emma (Sony recommended flash program for stock ROMs).
Emma downgraded my phone to 4.4.4 (23.0.A.2.93). However I still had the problem.
Next, I enter XDA and downloaded Flash tool. I downloaded one of your stock ROMs: 23.0.1.A.5.77 - Unbranded - Australia (1288-4214) {4.4.4}
I installed it and nothing. Same dead GPS.
So now I have no clue what might be the problem. Maybe the antenna got broken inside? How can I know if its a hardware or software issue?
Any help would be appreciated
Additional data:
Right now I have the 4.4.4 (23.0.A.2.93)

If the issue still exist with different firmware i guess its a hardware failure.

In sony it says its near the headphones plug. No more details.

Hi,
I have the same issues. It says since about two months. 23-26 sattelites found, but no signal and no fix. On 4.4.4 was OK, since updating nothing anymore.
I went back to Kitkat but still dead.
Anyone managed to get it back without sending it in??
Same problem...no GPS.anyone with a solution??? New motherboard? Soldering a antenna. Someone's got to have a fix for this problem.

Same problem and even tried to update to Android 6.0 with Marshmallow and still no GPS. 23-26 sattelites found, but no signal and no fix.
Any updates?
Hello,
I noticed since some time the same problem. I did a quick search on Google, and the problem seems more then usual after one of the official updates by Sony. The problem is discussed on the Sony Xperia Care support forums. All the affected user seems to suffer not from a complete signal outage, but rather from a substantially downgraded performance due to a bad SNR value and poor signal tracking, as can be seen by using the GPS Test app.
Resuming what has been written in the threads, all the following operations seems not to solve the issue:
- factory reset / repair with PC companion
- downgrading to an earlier release
- installing a custom ROM
- returning unit at service
What is annoying is the total disinterest by Sony that seems to ignore the problem, maybe they only want to take time to better understand the problem. If anyone should have news about this please let me know, because the only solution for this issue for now seems to be wating for a solution!
Thank you!
Same problem. Original Kitkat. In May worked excellent. During August I mentioned,it dosn't work. Some photos had changed infos about time and date of creating. On camera disappeared SCENE function in manual mode. When I allowed gps function on camera, gps worked immediately. Unfortunately only once. Camera Blocks gps?
Same problems here...
Hey, same issues here. I think it's just really slow to connect. I've recently sent my phone in for a warranty repair with Vodafone. It came back and was still broken.
Today however... I checked my phone and itw as working again (for about half an hour). Now I'm getting nothing again.
I've tried everything suggested, even down loaded AGPS file etc. But nothing seems to work.
Mega frustrating!!!
the only way for today is replacing motherboard... sony sucks. never again
I just wrote on the sony xperia support forum, somebody talks about a fix they provided for the xperia m series that seems to be affected by the same issue. But for our z series it seems not to be any fix at the moment.
After suceeding the GPS diagnostic test in the settings once, the GPS seems to be fully broken with no tracked satellite at all (before it was at least tracking a few satellites with a very poor SNR, now nothing according to GPS Test app). Repeating the GPS diagnostics now always results in an error. I'll try the warranty return but I'm pretty sure they'll give me a faulty device, as many other here and on the other forum have experienced.
Same problem ... just got the phone days ago.
Any solution ? or do I need to return it ...
I had issues with GPS, could see satellites but no fix on any. after expired warranty I rooted it and used 4 different ROMs, worked on all of them. instant lock on min 6 satellites. I am aware it could be HW issues but this is my experience with this problem.

I'm more and more convinced that this is a SW issue. Sony did something wrong when updating the firmware in August 2015. The fact that the satellites are visible comes in my opinion from the AGPS data, which loads the konwn satellite positions from the Internet. Instead, the problem seems to be the locking of a satellite signal, and it seems that something is disturbing the GPS antenna. If it comes out that this is really the issue, it is very disappointing that Sony didn't do absolutely nothing to solve the issue since last summer.
I'm using CM12.1 nigthlies and since about December/January I have the same problem. So a custom ROM does neither help nor prevent the problem. In addition to that, compass is uncalibrated and I don't get it calibrated again. Really sucks, last year I used the Z3C for lots of outdoor navigation, and suddenly something has happend which makes the device unusable...
I did root with kingroot and changed /etc/system/gps.conf as described in code.google.com/p/android/issues/detail?id=81140#c695
Now my GPS is locking again.
Did not help for me. Currently I don't even get bad fixes, I get no fixes at all. Never ever, even after hours in the open. This sucks.
Hi,
Disabling google maps helped me. Before 0 sats visible, after disabling it locks within seconds.

I had the opposite experience, I had no lock, I was trying everything, then I opened maps and I had lock in under ten seconds.
I wonder if it's a glitch in accepting the google 'we're going to follow your movements' contract. Because until I agreed to that, gps didn't work.
Hi,
I have Xperia ZR C5503 phone about a year. Until 2 months ago I was using Android 4.3. When Lollipop update distributed I upgraded it to 5.0.2.(official)
But sometime after the upgrade my phone started not connecting wifi. It sees the available networks but not connecting them. The signal drops to lowest level about a second while trying to connect and it fails. Also I was using my phone's wifi tethering feature to share my internet to my pc. However wifi tethering is also not working. I enable it but I think it can't work as router. And lastly, I tried to send a file to my phone via bluetooth and it also enables but no other device sees it. I also have low sound on the phone and I can't hear people I am talking to.
So I got frustrated this saturday and downgraded to official 4.4.4. But it was same. Later I unlocked the bootloader and rooted my phone, installed recovery software. With that recovery mode I cleared all caches but the problem still countinued. Lastly I installed an unofficial modified kitkat to my phone but those problems still appears. I don't know why this phone is so problematic for me. I don't know if it is software related or hardware related. Now that my warranty is no longer valid.
Could you give me some ideas to attempt to solve these issues?

Hi,
I had dropped my phone maybe 1 or 2 times but not from high heights.(~ a meter) But that was more than 5 months ago. I am having this issue since last 2 months and I am sure that I didn't drop or harm my phone in any way. However I wash my phone, do you think that could cause that? Just effecting wifi and bluetooth components?
It's not true about dropping the phone make that errors appear, there are many people with same issues, this phone have manufacturing problems, it's not software
My brother have same problem and he never dropped the phone. Just take a look in Sony forums.
Btw, my brother's phone lost Bluetooth connection, NFC, WiFi, Sometimes WiFi works making some pressing in the NFC spot some seconds, but sucks anyway :/

How can i make the wifi stable? it drops in and out sometimes.
Wifi problem
my sony xperia zr has the same wifi problem it says scanning trys to connect the signal drops and again starts scanning..
I stopped the wifi service and restarted my phone and the wifi worked for a day and again the same proble.
Do anyone has a solution for this??
I have been facing the issue of wifi not connecting, since my upgrade to 5.1.1.
My research has led me to believe that the issue may be software based. However I'm not an expert in the field. And i was thinking of downgrading back to an older version of lollipop when the wifi was not dropping.
Can anyone advise on whether this may be a smart move, or a completely useless one?
Also is there a diagnostic protocol I can go through that could help me figure out for sure whether my wifi is busted physically, as some of you suggest here.
Thanks
Josette
I've tried the method "settings global put tether_dun_required 0" but when i reboot my Z5, the value comes back to 1 ... (and of course wifi tethering is not working, going thru USB is ok)
I'm discussing various points here. Check out everyone of this point and get a fair idea from where problem is originating.
1) Go to WiFi Settings > Keep wifi awake during sleep. Here the string value should be "Always"
2) Under stock firmware there are numerous battery optimisation. Some of them kill WiFi so battery can saved. Now disable this features if you want no drops in WiFi.
3) If both of don't work, head over to Xperia ZR General > Search for your specific device FTF. Flash it via flash tool. This should reset all wifi drivers. Don't opt or apply any battery features and use WiFi. If still issue exits then you're in bad luck.
4) Check for other WiFi access points. Check your own router's webpanel and see somewhere broadcasting and multicast signals are ticked. Also check your WiFi is at 100% of it's performance ( 100% transmit power)
5) Hardware issue. Most of the software part is not causing issues so it's safe to say a hardware issue is causing this. Now, long time ago when 5.0 was released for our device I read article regarding ZR. The user had constant WiFi drops. His issue was that his WiFi soldering was poor inside hardware. He soldered it again and his wifi drops were no longer a problem.
People also experience various bluetooth/tethering issue. It's important that people should gain knowledge about firmware flashing techniques so that device would get reset and you yourself could diagnose the problem. 1 in 0.7k unit has software/hardware issue in manufacturing. Sony provides diagnostic app, search in play store ( I'm not sure about this). Hope this answer helps many.
hii.. so did u get any solution for the problem ?
i am facing this problem since one month. i tried rebooting my phone many times. i even tried factory reset. but nothing has worked till know.
if u have any solution please inform me.thanku
Wifi Issue.
Hello Guys,
I have same issue in wifi after 1.5 Year of phone. Can you please help me on that. Does any one knows any other technician are repairing this phone? as SONY says they are not able to repair phone which even they developed. I do n't why such phones developed.
1. I have repaired phone using PCC.
2. tried reset
3. tried without stamina mode
4. tried with wifimanager app
but nothing works....
If you guys any suggestion any hope please let me know.
Thanks.
I just bought a second-hand Xperia 1 ii XQ-AT51 and didn't noticed then that Wi-fi and Bluetooth are not working.
And also that the bootloader is unlocked.
Besides from those issue and that the charging seems to be regular charging, not fast, everything works fine (NFC, Mobile Data, camera, features).
I don't know what the previous owner did, he clearly did something because the bootloader was unlocked; and asking and reading from other post, seems that nobody had these issues when unlocking the bootloader or rooting this model.
I locked the bootloader and tried repairing the software with Xperia Companion. Same software 58.1.A.5.507 (as I see the latest) before and after repair
Guess what: nothing different, although repairing was successful.
Then I unlocked the bootloader, flashed twrp as recovery (probably not necessary in my case) and flashed the stock software with Flashtool, latest from xperifirm (the same version I had before).
But I got some messages that some 3 things didn't flashed (not saved them).
Still the same.
Under Settings -> About it says Unavailable at Wi-fi MAC address and Bluetooth address.
With code *#*#4636#*#* I can see that the Wi-fi MAC address is 02:00:00..... (see attached image).
With code *#*#7378423#*#* at Bluetooth says Enable Bluetooth, at WLAN says enable WLAN, but on another Xperia I can see that it says OK for Enable an then Searching (see attached image).
Do you guys have any idea what to try to solve this issue or what to test in order to find the cause?
Thanks!
hi man ,i have same this issue with my mark II (XQ-AT52) , do you find out the way to turn on wifi and BT ?
Unfortunately no. After an Android/Security update the phone started to restart in about 2 minutes at max. So after 10 seconds or 1 minute it restarted, but not suddenly (like if you disconnect the battery), it was restarting normally. Then I tried software repair, but the phone would be stuck or get out of the flashmode. Enters fastboot but it wasn't seen by PC with adb devices command.
So now I have another issue that most probably will leave my Xperia as a brick. Sadly, because I really liked it.
I have now a SH Galaxy Note 10, but I'm planning to buy another Xperia when this brokes.
I also had the exact same problem as you, so I gave up later, when Android 12 push out and i upgrade but didn't solve problem, so I was wondering whether to continue using it without wifi and bluetooth or send it to Sony for repair.

On mine I also noticed after I bought it that it was opened, so I didn't found if it was hw or sw related, but since you also had this problem probably it is a software issue, or at least not a hardware issue because someone opened it.
Especially if yours is in warranty, I think you should send it to Sony.
If i use a third-party rom like miui , WIFI and BT sometimes can be opened and used, but it will cause the system to crash, so I also think it is a software problem ，maybe related to the persist partition 。
hi guy，I sent my mobile phone to Sony for maintenance. After they tried to update the system again, they told me that I needed to replace the motherboard, which cost $400 , so I gave up and now use the unofficial rom
