About a year ago I bought a 55" Philips Android TV and 2 weeks ago I had to get another TV, so I decided to go with a non android TV plus the Shield, which turned out to be the right choice.

But the thing is that only now I realise how bad the Android TV on the Phillips TV performs, is slow, it freezes, it has this weird issue that the it runs out of space when I connect to it a 2tb HDD with lots of videos (I'm pretty sure it's because it saves screencaps from each video but then there's no way to delete them), also some apps won't work.

I've tried some things to make it run better like limit the number of processes, disable drawing but it's still bad, or at least nowhere near the Shield.

I don't see at lot of threads about actual Android TVs in this sub so I wanted to ask if anyone has some tips or someway to make it run at an acceptable level.

After using the Shield I find it very hard to use the Phillips TV, but also I don't want to buy another Shield for it, or even a Mi Box, since it's not really about the money but the redundacy of having the same system in two devices in the same screen, and also an additional remote.

Any thoughts? is there a way to root an Android TV TV?
