There are many problems with my UE46F6340 television that I bought in 2013. Interface and channel switching performance is very bad compared to old versions. I'm using game mode for my Xbox console but the latency is still high. You can make enhancements for the basic functions of the TV.
@ZiasWen, Did you installed latest firmware 2130.0 ?
Yes. Just a minor security update. Nothing has changed.
@ZiasWen To be perfectly honest if you have the latest update and have experimented with Settings not much other advice for a 2013 model. At this point issues can be expected which are likely to increase over time. Some information here on expected lifespans of Smart Tv's https://techpenny.com/do-smart-tvs
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
