[Cyberlife]

Hi

my TV models is 43W805C

After installing Android 6 v3.865, pictures is not clear and sharp as before.

Satellite reciver power is low and pictures pixelated Especially in HD channel.

Can I go back to Lollipop?

What was the last Lollipop version without problem?

I have this "pixelated" issue too but only on some UHD channels on Hotbird 13 and Astra 19.2, even though Singal Level is 80% and Quality Level is 90%.

Cannot figure out if this is a Satellite transmission issue since this does not happen always.
