I'm currently using an A23 and while scrolling through most newfeed I thought I'd throw in an idea.
Samsung has previously used the side mount / back mounted fingerprint scanner as a scrolling feature for its top tier smartphones.
Currently a few apps (on and off Google Playstore) gives users that option. However, youll have to root your phone to use that feature and that opens your phone to vulnerabilities. But, it would be great if this was an official option all Samsung users got to choose.
Hope you folks at Samsung could add in the next update for most mid tier smartphone updates?
