Users shouldn't be allowed to type letters in phone number field

[itsPronay]

Summary:
I can type letters in the phone number field, and can type more than 10 letters/numbers.

What did you expect the app to do?

I don't think people should be allowed to type letters in the phone number field. Also maybe we should limit the number input to a maximum 10 digits. ( since a phone number is of 10 digits)

Possible solutions

1. numeric keyboard only
   
   or

2. shows an error message when a character type is entered
   

Maybe we should also implement this for the account number section
