[Q] [Xperia V] [9.2.A.1.210] Unstable wifi - Sony Xperia T, TL, TX, V

Hello,
I upgraded my phone to the unbranded/Nordic version (9.2.A.1.210) from the original 9.1.A.1.140.
While this brought many positives (support of BLE for my forerunner & good battery life), it also brought some negatives:
- A terrible clicking noise when the camera is auto-focusing (clearly a known bug in all JB version ...)
- A very unstable wifi
On this second issue, I have not seen any other report of the issue.
The symptoms are quite basic, after some time (around couple of hours), the phone will no longer associate with any wifi.
The only method I found was to enable/disable the airplane mode to restore normal wifi operation ...
I have installed wifi-fixer for having more details, since the wifi is looping on the association mode (could be authentication errors on these known network). Of course, all authentication info are correct as the phone will connect properly once going through the airplane mode ...
I also re-flash that firmware, from the .ftf but also forcing it from Sony SUS ...
At this point I reverted back to 4.1.2 as I'd rather have less features but reliable one (wifi is flawless now - well just as it should be ...)
Anyone else with the problem ? Any solution identified ?

Same problem Here
Would you please point me to the tutorials to get back my phone to 4.1.2, thank you?

Just follow the guide in the general section (i.e. retrieve the right .FTF file and use flashtool), this is very straightforward.

Tried with the ROM from Singapore, same issue ...
=> Association rejected on all known wifi
(using the power button to cycle the airplane mode restore the wifi for 10-15 mn)
Any advice on how to troubleshoot ?

Maybe it's your wifi that gives problem of compatibility when you're on 4.3
Try with another wifi if you can..
And try to change some settings of your current wifi like number of channel, kind of encryption, and so on..

In fact the problem is more complex as sometime my wifi appears to be ok but I do not have any connectivity ...
Now, I believe I found some interesting infos:
=> prb is directly tied with usage of Bluetooth (especially 4.0 BLE)
When the wifi is 'broken', disabling BT will indeed restore normal wifi operation ...
I could not notice the issue before since Android 4.1.2 do not support BLE ...
I've notice others thread reporting WIFI/BT issue (notably around support of smartwatch)
In my case, I'm trying to have my garmin GPS Watch to pair with the phone, this is were the prb can be easily reproduced

I have the same issue! That damned Association Reject!
I can confirm this is due to Sony 4.3 as Wi-Fi still work normally on my other 4.3+ devices (Nexus 7 2012, Galaxy Nexus)

Same here
i have tried numerous methods to fix this so far no luck..im on ub flashed 2 3 roms even stock rom with sus

One observation ...
This time, running stock .210 but not installing my BT4.0 Application (Garmin Connect), I only had the Wifi/BT issue once ...
I will install the application but not connect to my watch (Forerunner 620), to see where exactly is the breaking point.
After all these, I will certainly consider unlocking my bootloader and try the Omni ROM (as I see Walter79 is extremely active)

Milestone Wi-fi/3G connects but not send data

Hello there,
As a newcomer, I found out these foruns filled up with great information and guys willing to help, so came here to ask for some help ....I am both excited and dissapointed with my brand new Milestone. Bought the handset about 5 days ago, which came with Android 2.0. Then updated it straight away to version 2.1 via "Motorola Software Update". So far so good ...here´s the problem I am facing :
While connected to wi-fi or 3g(issue is easier to notice due to 3G icon at the task bar, which points out in those small arrows data that is being sent/received) phone stops to receive data out of the blue. All connectios are cut off(it also happens when the handset is locked up). Some basic trouble shooting i did:
- tested all pcs connected to the same wi-fi network. No issues detected for these
- reset wi-fi router configs. Didn´t work
- tried other wi-fi router. Presented same issue
- swapped another carrier chip to test 3g connection. Presented the same issue
- tested my GSM chip on ther phone. Worked properly
- Reset phone to default settings. This time the connection took longer to drop, like 30 minutes, instead of the usual 10 minutes. After the first drop, it´s started behaving the same way again.​
It seems pretty much that there an issue going on here (obvious...hehehe). I am considering the following:
- Might be a software issue. So, right now i am downgrading it back to 2.0 version, check if it works properly and then move to 2.1 hopping to get the issue fixed.
- Use retailer warranty and claim for a new phone =/​
Could you guys help me out ??
Thanks in advance and Best Regards !!!
Guys, after downgrading version to 2.0, phone stills presenting the same issue. I think it´s turning into hardware issue =/....does anyone have a clue about it?
Thanks and Best Regards!!!

Odd WIFI Disconnects - Is this normal?

Hi, I have read through every search thread on the galaxy mini in this forum but no luck finding something similar
I get odd disconnections from WIFI. If I tell the WIFI to never sleep, the connection is solid and never drops.
However if I have it on the default "WIFI sleep when screen turns off" (for better battery life) then randomly when I bring the phone out of sleep to use it, the WIFI does not reconnect. (The WIFI at this stage is not "scanning" or trying to reconnect it is simply "disconnected")
It reconnects fine some of the time but other times it will not have the WIFI reception bar and there will be no internet access through my router. I have to manually turn the WIFI off and on again for it to re-establish a connection. **
Any ideas why this might be happening?
I have tried this on 2 different routers with the same results
3G is completely disabled
Phone is completely stock, and I have tried a factory reset.
I have reduced lease time on my routers from "forever" to 10 hours
I have had this happen at the side of the router so it is not a range issue
Model number : GT-S5570
Android version : 2.3.5 - (Samsung updater on the phone tells me this is the latest version)
Provider : tescomobile.ie
Thanks

Is that update actually official? Everywhere I look regarding that gives me links to download from Hotfile.com, I am a bit wary upgrading from a non official source and I can't seem to find the update on the Samsung website. You don't have a link do you?
I am hesitant as the phone is only a month old and I don't want to do anything that will affect the warranty.
Thanks for the quick reply.
don't worry they are stock firmware provided by Samsung (not officially)
and they will work great

The official firmwares provided by Samsung (see sammobile.com) but flash it according to your region (for example I'm in Indonesia so I flash DXKPD) if u don't wanna void your warranty
Edit : or if u still hestitating, use KIES to upgrade your phone

[Q] CM11 WiFi Connection Issue

Hey guys! I have only just joined XDA Developers so please excuse me if I have posted this thread in the wrong area. I have a Samsung Galaxy S Advance (GT-I9070) running stock Jellybean firmware (4.1.2 ITV) but as you all know the stock firmware for this device is full of bugs and freezes often. I successfully rooted my device and installed Team Canjica's CM10.2 ROM (4.3) from the thread on XDA Developers but the WiFi wasn't working. I then installed Maclaw's CM11 ROM (KitKat) because I thought that might solve the issue but it didn't. Here are the details:
Device scans for nearby wireless routers.
I type in the password for my home router.
Device saves router. "Saved, Secured" message displayed.
I tap on my home router in the list to connect.
Device says "Connecting" for a couple of seconds and then goes back to saying "Saved, Secured".
I browsed through the forums and some users suggested switching WiFi Frequency to Auto and turning off WiFi Optimisation but neither of those methods worked for me. The ROM was installed successfully and all other features are working properly so I don't think that is the issue. And my router settings are also alright since I am able to connect to it from my Nexus 7 (2013) properly. Can someone please provide me with a working solution for this issue? I will start receiving very high data usage bills soon because my data plan isn't unlimited. Thank you!
Is your ssid hidden (not broadcasted) by any chance? i had those troubles on hidden home network. Sometimes it worked after a while, sometimes it didn't. What helped me is to broadcast ssid for a moment, get connected with phone, remove broadcast (it will reboot router so phone will lose wifi for a moment). Then somehow it got connected normally

I just checked my router settings and SSID Broadcast is enabled. I tried flashing OmniRom 4.3 thinking that this may be because of a problem with CyanogenMod but the problem still persists. Is there any additional kernel that I was supposed to install perhaps?
CyanogenMod 11 version ?

Just a detail to those who have not upgraded to JB stock and think it is impossible to use it without problems:
All bugs and freezes in Stock JB currently are perfectly finished.
I use STOCK, only with modified kernel (cocore 8.2) without freezes or bugs in months of use.
Enjoy the developer's work (cocafe), because without it JB probably would be impossible in SGA. However we have JB 100% functional and bug-free.
About KK and WIFI bugs:
The only KK (or based) ROM that used without WIFI bugs was RR 20140313.
In fact, the only issue is incall vol. in my experience.
WiFi Direct, Camera -> Panorama is laggy , Screen Recorder not working Not Tested
I also noticed that the battery is worse durability.
But I went back to JB Stock -- personal preference.

Actually I did try that method. Flashed Samsung's latest stock firmware I9070XXLQL (ITV) and then rooted and installed CoCore. To be honest overall performance was much better and UI smoothness was improved. But after a couple of days of regular usage with just a few basic applications such as a note taker, train arrival time, WhatsApp etc. the device started freezing up a couple of times a day again. I admit it worked much better than before but freezes and hangs were still quite frequent. Running OmniROM 4.3 now with no issues so far except for dialer FC, laggy panorama and non functional WiFi hotspot.

This means probably you have typed wrong password. Also check that in keyboard it capitalise first letter automatically. forget the network and connect again
WIFI not working with cm-11-20140521-UNOFFICIAL-janice and cm11.0_janice.nova.201406
Same wifi problem with cm-11-20140521-UNOFFICIAL-janice and cm11.0_janice.nova.20140601. Wifi not connecting even after giving the right password (used to work correctly with jb4.1.2 and still works with desktop) only showing saving and connecting wifi. Then the wifi connection is shown to be saved. If wifi does not work with cyanogenmod11, then what's the use of upgrading?
Is wifi is not working in any custom kitkat Rom?
Please suggest a solution.
Try couple times to connect. I remember sometimes I had to reconnect 2-3 times before it gets connection. And the problem with kernel was about WIFI not turning on at all, it was not even search SSIDs.

GPS sensor not working

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)
Baseband: 8974-AAAAANAZQ-00005-05
Kernel: 3.4.0-g0961cdf Build [email protected] #1 Tue Aug 19 19:48:36 2014
Thanks
If the issue still exist with different firmware i guess its a hardware failure.

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.

Wifi, Wifi tethering and Bluetooth is not working

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.
