summary
Developer Options surfaces concrete debugging levers: take bug report produces a giant text/zip (around 200 MB) with logs, view hierarchies and top output; pointer location shows red touch points and blue trails; show layout bounds paints margins and optical vs clip bounds so mis-tapped views become obvious; GPU rendering overlays per-frame bars with a 16 ms target; overdraw highlights >4x waste in red; animations scale goes to 10x; don't keep activities kills activities on backgrounding so save/restore bugs surface. All work on-device with no extra tools.
