I upgraded from a P3 Pro to a P4 now my FPV on my Samsung Galaxy Tab is pixelated with occasional green lines going through it but it worked perfect with the P3, any ideas?

The Go 4 app is a little more power hungry than Go.

Yep, what he says lol

You will need a device that has a least 3gb ram (nvidia shield K1 only has 2gb but works well)  and a octa core cpu, if you want to stick with the Tabs, then the Tab S2 running android 6 is flawless, android 7 is problematic but workable.  do not confuse the Tab S3 with the Tab 2 either,  always check the spec, 3gb ram and octa core is minimum nowadays...

Thanks for the advice will have to look into getting a new tablet.
