I'm having trouble finding a tablet mount that fits the Lenovo 4 8 plus as the on/off button is where the clamp is. What tablet holder did you go for?I've been using a Lenovo Tab3 8 Plus (AKA P8) for nearly a year with no issues running Go 4.
Specs: Lenovo Tab3 8 Plus - Full tablet specifications
Nice screen, 3GB Ram, 2GHz CPU and not too much proprietary bloatware.
Only downsides are Android 6, too wide to fit in RC arms so needs a tablet mount.
