Install LineageOS and Break your Nvidia SHIELD Away from Google
If you want to maximize performance and reliability on an Nvidia SHIELD, install LineageOS and unlock it from Google bloatware.
About LineageOS
"LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway."
They also offer another package that contains the Google parts.
If you have an older SHIELD, this is a great way to increase performance. By eliminating the Google bloatware from Android, your SHIELD will have more resources available for games, streaming, and other apps.
If you sideload apps, you don't need GooglePlay or other Google apps. YouTube can be installed as a standalone app with the added benefit of no apps. Search for YouTube Vanced, or YouTube Mod to find stand-alone apks.
