I have a lifetime plan to one of your other apps and I happened to run across this through that app. I'm not seeing what font it increases. I haven't seen a font size increase anywhere. Not on my home screen, not in my text messages, not in any of my apps. maybe I'm doing something incorrectly? it has a notification in the notification bar and I have it set to 180%.

I need more information to check what the problem is. Please send me a log by going to:
Big Font ＞ Settings ＞ App log ＞ MENU ＞ Email ＞ select Gmail
Please describe the problem in the email; otherwise, the system will ignore the log email.
Please also attach some screenshots of the problem.

This app has helped me a great deal in the past. Earlier I was able to increase the font size to 250% but now I am only being able to increase it till 200%. Every time i try to increase the size to 250% the app prompts a message on tje screen saying -"This device disallows you to change the system font size to 250%(2.5x)." I have not changed any settings on my phone. Kindly address this flaw. Thank you.

Google fixed the problem in the 2021/04 system patch so you should be able to get it fixed when you get the new system patch.
For how to get the 2021/04 system patch, please contact the device manufacturer.
