IIRC app stores downrank apps that are not regularly updated too, hence the vague “bug-fixes and improvements” updates in many apps. But seriously, how much could a developer update in a calculator, habit/medicine tracker, sky map, or any other app that is a complete feature?












Samsung Galaxy S5 was/is a good device for tinkering. Supports many custom ROMs from CyanogenMod to Lineage to Ubuntu and postmarketOS.
Has a removable battery, 3.5mm audio jack, SD card slot. IIRC it worked fine on 3G, but did not support calls on 4G.
