Fossify – A suite of open-source, ad-free apps

I use them and like them. One thing to be aware of with the dialer (that might not be unique to Fossify): when dialing the number of an emergency service (like 112 in Germany), there is no indication in the app's UI that something is happening and it looks as if the call failed and you will be back looking at the dial pad, even though the call will eventually be connected. The reason is that these types of calls get handled by something deeper in the Android system and will show up neither in the "calling" UI of the dialer nor in the list of calls.

My phone crashing when I dialed 911 after a car accident was the reason I stopped messing around with android roots and custom roms and whatnot. When it comes to my phone being a phone, I need it to Just Work(tm)!
