It is not very fall resistant and has since yesterday the ever-popular Spider-App on the display (seat height on tiles).
Whatsapp worked for a while not sure, making problems when using only non-mobile Internet.

The battery life of Nokia is significantly better than the apple, that was the old treaty there.
Let's see if we can even replace the screen, replace the display would be an economic total loss.
