when did they bring back the "clear all" button
(when you hit the recents button) I can't believe they actually restored a feature that they'd removed by accident during an update this is wild. how long has it been back? how many years did it take them to accomplish this
This very well may be OEM or custom ROM dependant.
GrapheneOS has it on the very left (as shown above), which requires scrolling, modern Samsung and IIRC older LineageOS has it on the bottom, always visible.
Which LineageOS are you using? Mine has is on the very left and I wish it was on the bottom.
The bottom button was on LineageOS 14-15 (Android 7-8 equivalent... So rather old now)
