I've owned 2 Sony Bravia Android TVs (x850c and x900f). I'm extremely dissatisfied with how little firmware/software support Sony provides these devices, the length of time between security updates, the total lack of updates after just a couple of years, the poor/buggy performance of these televisions over the years, etc.
In both cases, I've ended up just totally disconnecting both Sony Bravia TVs from the network and using Nvidia Shields instead. I'm in the market now to replace my oldest Sony Bravia, but wanted to know which brand of smart television with Android TV has the longest firmware/software support lifecycle and if there even is one that supports the device with updates more frequently or for longer than just 2-3 years.
It seems ridiculous to spend this much money on a device to get such poor support so quickly.
Any suggested brands I should look at that may be better than Sony? Just from a software/firmware support point of view, not screen type or TV features.
