Help Activity phone not responding

[soledad]

Last night my phone died (it wasn't supposed to since it was fully charged before i slept) and since then I haven't been able to make any calls. When I try dialing or select a contact the screen freezes and sometimes it shows this message: 'Activity Phone not responding, would you like to close it?'.
I tried uninstalling some apps, put it on plane mode, charged it, removed the battery and nothing works. I was thinking of a factory reset but i'm scared of it.

Anyone knows how to fix this?

Hello and welcome to Android Forums soledad!

Sorry to learn that you are having problems with your Galaxy S2.

There is one thing that you can try before doing a Factory Data Reset and that is to wipe your cache partition to get rid of an detritus that may have accumulated there. It is a fairly simple and straightforward process that will not affect your phone, user apps or data. See the following video on ow to do this...

If this does not solve your problem then a Factory Data Reset would be your next option. The steps you need to take are detailed in...

I tried wiping the cache data but it didn't work, so i had to do the factory reset and i can make calls again. Thanks!
