I have a Shield pro 2017 that is running really slow with a bunch of issues. The 9.0 update (ads on home screen one) killed performance and now it’s slowly been getting worse. I was thinking of just reformatting but have been looking into debloat it as well ( https://florisse.nl/shield/). Anyone have any other tweaks they’ve done on these? I just use it as a client for Plex and YouTube mainly.
Reformat, install Flauncher, and run the adb commands to disable the default launcher. My 2019 pro was getting slow and formatting it fixed it. It’s running 9.0 but I haven’t really had any issues with it after replacing the launcher.
