that's probably true about the tiles, but, i'm willing to bet, most people don't care and just want the content to look good at the resolution it's supposed to or gets uprez'd too.
exactly how much time do you spend looking at the tiles? i'm not trying to be funny but, your the first one who ever suggested possibly buying another device to potentially get better looking/hi-rez tiles. i guess they really mean a lot to you and bother you when you see them in relation to what you got with a different brand/OS.
do you still have the Sammy or the LG? i can tell you that this issue is not even on TCL's radar of things to change at least, not that they have shared with us thus far.
best of luck Papi.
