Post official upgrade to Android 4.0.3 and the scare couple of days earlier this post is of the issues that am facing.
1. The mobile network signal drops lot of times. Some times, the network is not found till a reboot is done.
2. Battery never says 100% charge complete.
3. Worst of all. Last night after battery drained, my mobile got switched off. Today morning I put it on charge and switched it on. Shocks of shocks, the mobile network is missing. Reboot still no network. Change mode to Airplane and again disable but still no network.
Worst of all, none of the service providers are also listed.
This is the most funniest thing I would have done. Went to System Settings -> Wireless & Networks -> Mobile Networks. Disabled Data enabled, Data roaming, Use only 2G networks. Then clicked on Network Operators, finally my mobile service provider was listed in the available networks. I select and then enable all the disabled options.
Back to normal. Back to work.
Any further issues will be added here.
