Hi @eric93 

Is the software on your phone up to date? Go to Settings > Software update > Download and install. Also, try a Soft Reset on the phone. This will end all processes and give the phone a fresh start. Press and hold the Volume Down and Power keys at the same time until the phone switches off and back on again.

Let us know how you get on!
