Can't be using a security lock screen or it won't show at all
I have the same issue. Using 2.7.0.0 teamwin recovery
If I have a touch wiz KK ROM(stock, infamous, xnote, Jedi), my data cycles in and off every 5 minutes or so, as if its sleeping. All have the same issue on my phone.
I have Odin full stock multiple times to try and clear the modem. Just odd
If I use a AOSP KK ROM (gummy, slim, temasek), I have no data connection issues at all. I prefer TW due to the better sound volume and lack of touch sound distortion, but the darn data is annoying.
Is there a buildprop setting I can maybe tweak in touch wiz to get the data connection to stick?
This is the speed average I've been getting lately. I'd rather be on Wifi, I can get up in the 30mb DL and around 10-15 UL. But this is crap.
After update to kitkat network keep going off every 5 minutes , is there any way to fix ?...
