Nougat 7. wont do much of anthing for the Sony TV Google TV Android platform given the 3rd world rubbish CPU and inadequate memory Sony uses @ Andoid TV 's like the rubbish edge bleeding 4K Triluminous wanna be HDR 2015 Sony 55X850C here .
I had to already
put an LED bar in the 55 X850C panel ,a main board and repair the PSU /LED board in it when it fried all that at once at less than 2 years ( poor thermal design and cheap panel like my 2013 1080P Sony Bravia but at least it is a 10 bit panel or a convincing 8 bit + frc panel ) .
I have a new entirely better Smart TV experience and stability in my way better 3.5 X brighter Genuine QDOT HDR 1000+ 2016 Samsung UN 55KS 8000 free (in here ) instead of the Sony from the aftermarket extended warranty on the Sony train wreck .
I kept and fixed the Sony 55X850C Rubbish for less than $200.00 in new salvage parts and some board circuit parts myself for another room just like my 40" 2013 Sony Bravia already.
I put new LED's in the 2013 Sony Bravia cheap 6 bit + frc dither panel for $18.00 in new salvage parts but like the other 55" Sony it was Cost prohibitive to repair at or by a TV shop in the field .
