I have seen people complaining about all the non removable apps they got which makes the device feel bloated and honestly I just couldn't relate because the only app I had other than google owned ones were Netflix . Maybe this issues is limited to usa only and they how they the price almost half.
Another thing I notice is that whenever I try to keep resolution at 4K 60fps, it make some sort of noise from tv speakers is that hdmi cable issue or the tv's ? 4K at 30fps works just fine and I don't see glitch colors (rare) like at the 60fps.
you can disable the apps that came with the box so they never load or update. Honestly the preloaded apps do not take much space so I don't know why people are so crazy over them being included.
