Hello there,
One of main functions I use is the GPS. GPS performance is being very disappointing on my Xperia M dual. It’s not anything related to signal strength, conditions etc. I used to GPS for so many years with different devices, including Garmin units, it’s really some problem with android. After researching the subject I discovered lots of users having similar issues starting from android 4.2.2. I tried upgrading to 4.3 but still having bad performance. I want to downgrade to 4.1.2 but can’t find the ftf file for Xperia M dual in this version.
After various tests I discover that GPS gives me stable fixes if I turn wifi and network OFF. So what I want is disable wifi and network GPS scans for agps data. Problem is there’s not such options to disable these scans on the Xperia M. How to do it manually or any app I can use to change these scan settings?
With network enabled, GPS is very unstable, losing fix every time followed be extreme slow fix. It’s incredible that I have a faster fix without agps support. In the end all this technology is worthless with this buggy android.
In the official google android forums there are google developers stating that there’s a know issue with gps until 4.3 and ask people to wait to be fixed on kittkat. What they expect? That I throw my phone and buy a new to have a bug fixed. That’s ridiculously lame.
Well, any clue on how to make wifi and network scans OFF is very appreciated. Something I can add to gps.conf to have this?
Thanks
Unsure on the GPS thing, but there's no 4.1 firmware for Xperia M dual. If you really need Android 4.1 in Xperia M dual you can crossflash Xperia M single firmware, but you'll lose the functionality of the second SIM until you flash another Xperia M dual firmware...
Hi mbc,
I see some threads about crossflashing M dual ROMS on C1905 but nothing about doing the contrary (C1905 ROM on C2004). Do you think it’s ok doing it? Should I just flashtool C1905 ROM, marking the option to preserve boot or just flash it entirely, including boot? I’m afraid of bricking my phone using a boot not designed for my model. Anyway, if things goes wrong with boot is always possible to restore old ones using fastboot mode? I’m really not sure what are bricking chances in this scenario, any clue is welcome.
I'm being really disappointed with this GPS issue. Tried everything, patches, GPS fix apps but nothing makes GPS stable. I contacted Sony support and by the way, they asked to run fix on Pc Companion and send device to warranty if that doesn’t help. My hope was sending it to warranty but it really seems to be a issue with android anyway. Im not alone: http://talk.sonymobile.com/t5/Xperia-M-M-dual/Problem-with-GPS/td-p/514313/page/2
In the worst case your phone would just flash the LED red and nothing more, but you still can go in flash mode from that state. If you are afraid, you can flash only kernel and system from C1904/C1905, I think that is sufficient. If something get wrong, you would be stuck in a bootloop, but in that state you could easily go in flash mode and flash C2004/C2005 firmware again to get rid of the bootloop...
This is funny ( it really is? )... I flashed just the kernel and system and after the process, at boot phone asks "enter password to decrypt storage".
My best bet is that I need to make a full flash to get rid of it, I hope. Arrrghhh.
Good news for me. I used a C1904 ROM http://forum.xda-developers.com/showthread.php?t=2410913 and eveerything works perfectly, except I lost the dual SIM capability, what’s OK if I can get the damn GPS working right.
Interesting enough, despite of the fact that the ROM is from India, it presented me the “Brazilian Portuguese” tick already checked on initial screen (yeah I’m Brazilian), with the custom keyboard, dictionaries and everything. For documental purposes I will post here if this ROM fixed the AGPS fix issues after testing it for some days.
Hi guys i have a lg g3 that has been running fine on kitkat
it the received the lollipop update OTA and all went fine apart from now it wont turn the WiFi on
you can click it on and it moves to on but seems to be always trying to turn on..?? without turning on.?
any ideas..?
I have done a reset etc still no joy
Did you try to reflash? (I think that you mean by resetting that you full wiped your phone and not reflashed the rom)

Same issue here.
I get around it by forgetting network then just signing in again. Wifi works perfectly until I leave the house and return later. Then I just do the above and viola, working wifi.
I've checked with speed test app and wifi is definitely working.
Funny thing is, if I switch off wifi then turn back on it also works.
Only when ive left home and returned later does this bug arise.
Hello guys,
This thread is a little bit old, but I am curious to know if you found a workaround for this issue.
I have the same problem as the OP (not at the second poster): since I received Stock Lollipop the WiFi won't turn on. When I try to, it says "turning on" for a while then acts like it is off.
I just bought my LG G3, NCIX the reseller, refuses to refund me or replace my phone...
I performed several factory resets and tried to flash different KK stock Roms. The weird thing is that the WiFi works with KK...
Thanks for your help.
Identical experience here.
I recently got a D855 16GB, which was on stock unbranded V10a, jumped through several OTA updates through V10g, V10j, and V10k (IIRC) all with wifi working fine before getting the lollipop upgrade OTA for V20c.
Immediately wifi will not switch on - the switch itself is on, but with the off section a lighter grey compared to the bluetooth switch.
On the wifi screen itself it says "Turning Wi-Fi on..." but after a while the switch reverts to off.
It's now had OTAs to V20e and V20h, but wifi is dead on both versions.
Note that this is stock and unrooted (never rooted) so I can't believe it's something I've done. Next trick will be to root and poke around /data/misc/wifi.
Does bluetooth work or the problem is only with the wifi? I also have the same problem, wifi, bluetooth is not working and when I check in the settings the mac adress it says "unknown".

Unfortunately this isn't a unique problem. There have been countless bad updates from multiple manufacturers. In this litigious world, I'm surprised no one has sought damages for bad updates that effect usability.
I have the same problem from yesterday. wifi and bluetooth seem to be turning on but they never turn on. i've done many factory resets but it didn't work. has someone found a solution?
^^^ Exactly the same issue. Would love a solution!
Same issue. Tried Hard and soft reset and have also updated firmware using LG Mobile Support Tool but had no success.

ok, after 24h with this problem I think I got it back to working. Let me explain what have I done:
1. Mine is a dual sim model, that I bought in hong kong by the end of 2014.
2. Yesterday, I removed sim #2 (no longer needed), without removing the battery. I had a couple of messages indicating to restart the phone, blah blah. Can't remember if I finally restarted it or not.
3. This morning I saw no wifi connection in my phone, only 3G. Tried to start wifi in the quick access menu, but this kept blinking, never starting wifi. Restarting phone... nothing. turning off bluetooth... nothing.
I figured out that the problem had to be related with the SIM as this is the last thing I had done with the phone. Thus, I tried this, with success:
4. I turned off the phone, changed sim from slot #1 to slot#2 and started the phone. Wow, it worked for some minutes, then stopped, then started again. Well, a good sign.
5. Changed again sim from slot #2 to slot #1: Wifi working again. After some time it stopped working, but soon started again. Hasn't given me more problems (after only 30 min, that's true).
Hope it helps.

HELLO
I have exactly the same problem and I think we're not the only...
D855 :
-Wifi and Bluetooth doesn't work.
-Wifi keep turning on itself and the battery drain..
-3g/4g works perfectly.
-Downgraded on kk and Wi-Fi works so it is not a hardware issue
-Even on fulmics Rom Wi-Fi and Bluetooth doesn't work
HEELP ME PLEASE
Got the same problem here. I have my G3 since november 2014 and recently I rooted it to install CM 13 on it and Xposed bcs I got tired of the laggy software of LG. One morning I woke up to drink some water and saw my phone restarting a lot of time... ok I thought its a simple bootloop. Tried to install CM again, didnt fix it. Flashed stock software and still... Bought new battery and new power flex and the problem is still there. I go into download mode, installed the software with LGs support tool and got pass the bootloop, but now wifi nor bluetooth works. I thought it's the software so I dared myself again to root it and installed TWRP and CM13, but it wouldn't boot. I installed then Liquidsmooth, based on CM13, and got it to boot up, but in the configuration menu where WiFi is needed to be added it couldn't turn on. I skiped it and in the middle of the process it started again to restart. I don't know if it's a hardware based problem or software... But I would like to try everything out before I have to buy a new phone.

I don't understand why it doesn't work because if you downgrade on kk versions your wifi & bluetooth will be back...

Have you maybe tried to change the kernel of your device? I have never done that so I am scared if I would damage something.

Here someone says it's the kernel that is having problems and installing a new one and going maybe back to the old one will fix it.

I installed CM13 and in the setup screen I actually had wifi and I could connect to my router. It was kinda strange. But bcs I have some problems beside wifi, the reboot thing, I couldn't test out if it works too. Try flashing CM13 or ROMs that are based on it like Liquidsmooth. Maybe it will help.

I tried flashing other roms but twrp says "unmount of /system failed: no such volume " "script succeeded: result was (0.20000)".. when i restart it's on bootloop NO CHANCE
I already had this problem with ICS (I never upgraded to KK) but only occasionally - Ever since I upgraded to Lollipop (5.1.1 French version) the phone constantly loses the connection to the network (and of course also to the data) while WIFI works perfectly, rebooting the device things are back in place, until I move again(specially inside the house).
At first I installed the TWRP recovery (full wipe) and the rooted the phone, then thinking to solve this BIG trouble I flashed Lollipop again, remade the wipe of all, left all the bloatware that the first time I had eliminated - but it didn't worked - instead of the triangle where usually appear the notches of the connection there is an "access denied icon", and when I try to call appears the message: "NOT CONNECTED TO THE NETWORK" - by the way I can not receve calls too while in this state (unreachable).
Has anybody had the same problem or can help me anyway? Should I downgrade to KK or ICS? (but I'm reading that's not going to be possible from 5.1.1!) Maybe I can try flashing another Modem? The rest of the telephone is perfect, battery consumption is better, camera, movies, fluidity: everything is ok but the telephone!
My BASE BAND is N7505XXUDOK4 and my BUILD VERSION is LMY47X.N7505POUDOK2. Thanks

About 3 days ago my phone started to have Wi-Fi disconnecting issues. I formatted everything outside of external sd card and put back the same rom I had installed with no previous issues, xdabbeb's 47a rooted following instructions 100% as I had previously. Still, wifi issues where it will connect / disconnect. Rebooting the phone or turning on / off wifi or even bluetooth has no effect. Complete randomness seems to "fix" it but wifi will only stay on for a few minutes at a time. Multiple other devices on my same network have no issues. Still, rebooted and even factory reset the router just to be sure. No change.
Something I thought was an isolated issue, I had a "no sim" message a few months ago and Verizon replaced my sim card and the problem seemed to go away. Today though, while trying another reformat, I got the "no sim" card on the initial setup screen and before even finishing the setup via wifi, the wifi disconnected multiple times.
I'm thinking hardware is to blame especially since there were no apps installed to conflict with the os software.
I'm really not wanting a new phone, should I look to replace the motherboard? I can diy it np. Or, should I bite the bullet and buy a ::shutter:: new phone.
Orrrr... is there anything else I should try software wise?
So since having issues and formatting down to internal storage and reinstalling the stock rooted 46a kdz with no positive results, I flashed the 10b and attempted to take the OTA's. The OTA's failed for 10b so I flashed the 24b and was able to take all the OTA's. I'm on 47a right now and haven't had any wifi issues. I'm going to give it a few days of usage to see if it's "fixed." Afterwards though, I plan to go back to the stock rooted 46a so I can use my rooted apps like titanium and hopefully find the issue still fixed. I do know there is a kingroot option for stock 47a, but I also find a lot of negativity about it's communication with sensitive data and installing apps behind the scene so I'd rather not go that route.
I'll keep updating in case anyone else has similar issues.
i used only stock roms since months. two weeks ago i tried cm14 for one day but went back to imperium. i do not know exactly when my problems start, but i think it came with flashing cm and empirium backwards. so the problem is, that i have only slow internet connection (edge) until i reboot my phone. after the restart 4g works again. after i loose connection it only connects with edge again.
i tried any available rom, kernel and modem, but all have the same problem for me. i think the original stock v20d seems good (flashable zip from xda, cause i have no windows for kdz flashing).
Somebody know what to do? I dont think it is hardware related, because after a reboot it works....
