I am having various app lock ups and errors that is requiring cache and data clears. For example I run an app called waze(navigation) it requires gps and 3g. I started getting "no network" errors. After checking their website had no server errors I cleared data and cache for that app and bam... up and running fine again. The problem is that this is happening with random apps almost daily now. Gallery, camera, internet, news feeds, weather... ect. Even going into settings/applications will freeze the phone. Plugging in the charger will cause a reboot sometimes, or unplugging will freeze the phone. I also just replaced the SDcard because it just up and failed last week. Anybody have a reason why all this would be happening? Any suggestions as to fixing the problem?
