I have 2 different Androids, on two different non contract service providers.
Comm100, other than some minor bugs, work perfectly fine on my Virgin Mobile (Sprint) 3g plan with an LG Optimus V phone.
Android 2.2.1 - Kernel 220.127.116.11 - Build FRG83
However, I recently purchased a new 4g phone from T-mobile. On this phone Comm100 seems to auto logout after about 10 minutes of the phone being idle.
It will display that comm100 is running in the notification area, but when I reopen it, it is sitting back at the login screen.
Phone Model - Samsung Exhibit II 4g - Android 2.3.5 - Kernel 18.104.22.168-perf-T679UVKJ1-CL625406se.infra@SEP-68 #3 - Build GINGERBREAD.VKJ1
I have seen another similar thread about this, last night, but was unable to locate it again.
