Here's a list of some Android apps I might start using some day or they are promising, but not there yet. See also: Apps, Programs, Operating Systems, Phones.
Fonecta Caller 3
Opinion: No. Background software that possibly creates problems with my Sony Xperia Tipo (Android 4). To fix the slowness for a while, I need to remove the battery from my phone, but the slowness starts again at some point.
