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.
