Are you on stock ROM? You could consider installing a custom ROM like Cyanogenmod and look if the bug also appears there. If yes, maybe something on you're device is damaged.

I think we'll all need a bit more info to try help.
1) How did you update?
2) Did you use ClockWorkMod Recovery?
3) What Kernel / ROM were you on and what did you flash too?
Give us as much as you can then perhaps we can help!

WiFi / Bluetooth not working

Hello guys. Need your help. A friend got his I9100 wet, let it dry only 1 night and turn it on next morning. Now neither WiFi nor bluetooth are able to turn on. I alredy flashed stock firmware I9100XWLSW_I9100XEULS5_XEU and root it. Did a Factory Reset. No success.
Can any of you give any ideas? is it a hardware or software issue?
Thanks.
i think that`s definitely a hardware problem as long as your friend get the phone wet. If your phone is under warranty take it to the samsung service !!!
Issue solved.
Issue solved. some internals were sulfated.

[Q] E120 signal

Dear all, I know I should reply to the develpoment thread but I have not hit the 10 post requirement.
recently I have installed the 4.4.2 hellcat rom on my e120l that was purchased in korea and am using it in China. I also updated the modem to mk3http://forum.xda-developers.com/showpost.php?p=48740262&postcount=25, evertime i remove the battery and boot up there is no signal. I must do a normal reboot to get a signal, anyone know how to resolve?
Can anyone at least tell me if it is a rom or modem issue? If you need more info please let me know.

Hi there. First off, since the i9505 model is an international one, it would be helpful to know what carrier / country the phone is originally set for. Also, what kind of wifi connection issue are you having? Does the wifi not even turn on, or it does turn on but doesn't want to connect?
wifi not working
-it is samsung galaxy s4 gt-i9505 I9505XXUFNB in the PHILIPPINES open line.
the wifi is not even turn on. this is just 1week with me.
THANKS
Hi..same with me..can't connect to wifi like TMWIFI..but others wifi is fine..even my s5 also can connect. .but my i9505 can't..just this tmwifi..any tips?
