This is modified IMSdroid adapted for economycalling.com.We use non optimized libraries to allow using of some more devices like tablets with nvidia tegra 2 processor.This client together with economycalling allows free calls (including video calls) and messages to other users, and cheap calls to rest of world.Known problems – on some tablets, client crash from time to time. If tablet switch network – it could cause problems with connection to site. Currently tablet must be rebooted.All those problems are seen on tablets, and not on phones.
