It is opening most of the time I am pressing the home button quickly. How can I uninstall the app? I can't uninstall the app.

Please add the feature of 60 fps video in galaxy m21Not the 2021 edition

Every time I used to set a sim on '3g only' but after some time it changes to 'LTE/3g/2g(auto connect)'.The device is not dual 4g. So I am keeping my JIO 4G in 'LTE/3g/2g(auto connect)' and I want to use My BSNL sim on 3g only because it is a 3g sim ...

What can I do ?
