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.
I connected to mine via ADB over ssh to remove the stock launcher and install FLauncher. It kept trying to launch the google launcher anyways so I removed play services and some other stuff also and just replaced the stock youtube with some third party client. Its been working ok so far! Every so often it will boot to a black screen (I think it fails to start the launcher) but a reboot fixes that.
