mobile

What's up everyone. I swapped my iPhone for an S5 that has MOAR ROM installed. The guy reflashed the phone clean when we swapped and when it booted back up I have no phone icon. I can get calls if someone calls me, but I have no icon to make a call and the lock screen icon doesn't work.

Is there any way to just flash an apk file vs. having to reflash and set everything up again?

Thanks in advance.
