When I type my phone # and PIN into the login screen the characters are not showing on the screen. However, the info is being entered because when I go thru the process and click submit, I get logged into my account. This problem just started. I have used BoostZone to manage my account many times since I bought my phone 8 months ago and previously could always see my login info as I typed. Other apps that require login, such as mobile banking, do not have this issue. Not a vital problem but I wonder what happened. Any ideas?
