About 3 weeks ago my Droid 2 started freezing up every now an again. I can go whole days where it works fine but there are days where i don't even put the battery cover back on because i have to remove the battery to get the phone back. when it is frozen up it will not accept inputs through the screen or the key board. I can still place calls by using the voice recognition. I can also still receive calls but i have to accept the call with the blue tooth. Sometimes when i reset the phone (via battery removal) it still comes back frozen up. Also some times it will draw either an all white or all black screen with the notifications along the top. The notifications sometimes will work and sometimes not. There has been no drops and no water damage to the phone. Any ideas? I did remove all the apps that i installed back to about a month ago.
