I'm new to the commuity of Fido but i'm a long time customer.
I got the new ZTE Axon and i don't like the call display, you have to slide up to decline or slide down to accept the call.
I prefer when its two buttons on each side of the screen like on my old Galaxy 4 mini.
Otherwise, i'm happy with the phone. Plenty of Gb and it charge up very quick.
Pretty much anything can be changed on Android. Would this app work for you? (Ultimate Caller ID Screen HD)
Never tried it, never knew it existed until a few minutes ago, so I can't say how well it does the job.
