I am looking for a good way to lock the screen on my phone without using a physical button (the botton is on the edge of dying so I am preserving it for turning the phone on).
I would like to lock the phone by movement or tapping somewhere on the touch screen.
(I prefer it if this can be done without using external apps but if necessary I prefer free ones without ads.)
The f-Droid app FLock seems like it would have been ideal, but it crashes before I even have the chance to test it ().
There's a built-in option that comes with Android 10 which allows you to lock the screen without using the bottom.
In your phone settings, go to "Accessibility" and enable "accessibility menu".
This will now put an icon on the the right side of your navigation bar. Pressing on the icon will bring up a menu, with one of the options as "lock screen". Pressing on that will lock your screen just like pressing the power button would. You also have the option to power off the phone in that same menu.
See screenshot below.
