Hi to all
,

I got a network problem with my T-Mobile Samsung Galaxy III (T999) with CyanogenMod 11, when I use the phone on HSDPA network (H+) and stop using the phone the device switch automatic to UMTS network (3g), I know this is "Fast Dormancy". The problem is the phone don't wakeup from 3g network (UMTS) anymore, resulting into no data and make/receive calls is not possible.

I have to manually restart the H+ connection or change to EDGE network (in EDGE the phone works good but data too slow) for use the phone. I try changing the base band versions, disabling Fast Dormancy, change system.prop and nothing help.

This is my actual setup:
Model: SGH-T999

ROM: CM 11 ( cm-11-20150208-NIGHTLY-d2lte)

Android: 4.4.4.

Base Band:T999UVUMJC and I try T999UVUENC2 first one work better in my area.

Kernel: 3.4.104
