Hi Joyce,
Thank you for contacting us. I'm not sure what's happening here, but the font size and style can only be changed in the phone's main Settings. I believe what's happening here is that you have some type of accessibility option turned on for the phone, but if that were the case, you should be seeing that font elsewhere in other apps.
Real quick, what type of phone do you have? Also, is the phone you just upgraded to the same type of phone as you had before? For example, if you had an Android device before, is the new phone and Android device?

I downloaded msecure to my new phone and the font size all changed to an open letter shadow type font that is horrible to read. I am having a terrible time reading this font. What can I do
