I recently upgraded from a 2012 Samsung Smart-TV to a 2015 model. Both are amazing machines with great picture quality and a lot of apps and awesomeness inside. The upgrade however feels more like a downgrade at times. I am pretty much consistently able to break the device in various ways through the most silly methods.
A little background on how I use it; I don’t have an aerial connected, so the “TV” part is unused. Connected is a PS4, a Raspberry Pi, and a desktop computer all over HDMI. The RPi is my main method of consuming media, and the YouTube app is frequently used as well. I also use HDMI-CEC (AnyNet) to control everything with the TV-remote. All of this worked great on the 2012 model, but the 2015 one isn’t playing along as well.
