The old man can't see the words on his mobile phone clearly with his eyes. Ask some Android software to enlarge or directly display large font caller ID, SMS and address book. thank you

I know this. I've installed it before. I tried all the software I could find.

You can install a large launcher, which is a desktop program that can completely enlarge the interface and build three different font size schemes. If you choose extra large, you can see it two meters away. The program supports simplified Chinese. Reading short messages and address books have large fonts, which are very convenient for middle-aged and elderly people to use.

In addition, if users don't have much contact, I think it's not bad to install a colorful old treasure.

There is also a program called bigfont, which can also be adjusted and entered manually. I hope it can be adopted.
