Factory reset doesn't prevent crash.
For the moment i am using SIMcontacts application to access the contacts. It doesn't crash & is easy to use. Contacts can be transferred to sim using contacts2sim app.
Any free app to access call logs to replace logsprovider ??
Background data has to be disabled otherwise gapp & Googleservices framework also crash. Just stop gap measures as i have not been able to update using kies due various reasons .
Is it advisable to flash stock or custom Rom using odin or whether updating using kies would be easier ??
I unrooted & then again used update.zip to root as i wanted to try out custom Rom. Please suggest which is the best Rom available which you have tried yourself . Personally i can live without wi-fi support for now as currently i am not using it. Any suggestions ????? :-)
