The LilyGo T-Watch-S3 screen interfaces are much simpler compared to the T-Watch-2020 v3.

I bought the LilyGo T-Watch-S3. There are generally promotional and application development videos for the T-Watch-2020 V3 on YouTube. In the meantime, I noticed that the screen interfaces and menus of the T-Watch-S3 are very simple. After upgrading the firmware, will we get rich menu contents like the T-Watch-2020? If I upgrade to the T-Watch-2020 V3 firmware, will those menus and screen interfaces come?

The watch-2020 factory firmware is written by sharandac https://github.com/sharandac/My-TTGO-Watch. This project is currently inactive.

Can we upload the T-Watch-2020-V3 firmware to the T-Watch-S3? Are there any issues during or after the firmware upgrade?

This is not possible, this needs to be adapted to twatch-s3
