If you can try it, please try Automatic small resize camera 2. It is upward compatible.
It is a camera application for taking compressed photos instead of memos in the fastest and shortest time and sending them by e-mail. You can shoot and send an email with 3 taps from the start of the app.

[Main usage]

1. Send compressed image by email using G-mail (3 taps of start, shoot, and send)

2. Take a compressed photo and save it in the photo gallery of your mobile phone (3 taps: start, shoot, save)

3. Compress and shoot, paste it on the line talk, and send it with other mail apps (start, shoot, share button, app selection, the rest depends on the app)

* 3 taps are for sending emails to two preset addresses via the Gmail server. In that case, you need a Gmail account and settings, and the setting method is explained in the app.

* The image reduction size can be selected from 1/1, 1/3, 1/6, 1/15, and 1/40, so the data saving effect is high. You can also avoid sending large files to others.

* A function to shoot videos with reduced capacity has also been added. You can't send emails, but I think you can shoot a smaller video than when shooting normally.
