i9100 strange problem
This is more of a question for very advanced users (possibly experienced in unlocking hundreds of phones with boxes like nspro or riff).
Very strange - the same unusual problem that I have seen now TWICE in two i9100 phones. Both from Orange (ORO) and unlocked I believe with nspro. Both were with older Android versions (4.03 or so).
The phones start OK and register fine on non-ORO network with their SIM. Calls can be placed and received. However after about 2 hours no new calls can be RECEIVED - the phone can still make calls, but when somebody else is calling it - the phone looks from the calling end like it is turned off or out of coverage area (or in some deep sleep of the modem). Once you try to place a CALL from the phone it works, and then the phone can RECEIVE calls OK - but only for another 2 hours or so.
The problem is present in both original 4.03 and latest 4.1.2 with any modem+ril combination that I tried, including the latest once from the original ORO network.
