I ran my Mi box for about 3 weeks, and it suddenly wouldn't even play a youtube video, i thought for a moment, and searched for the cache. It immediately started working again. I just thought other might want to know, in case their system seems to be slowing down.
settings, storage & reset, internal storage, cached data, ok
A good shout, I use this device a lot and sometimes when streaming it becomes very obvious that I need to either restart it or clear the cache (didn't know you could until reading this). YouTube videos would stutter like crazy until I cleared the cache. Be great if there were an automatic feature for it to do this or an easier way.
How?
Seems to me like the Mi Box was released without being completely ready. One shouldn't need to immediately do a full factory data reset (possibly multiple times) to get it to function right, or periodically delve into the menu system to clear the cache. Hopefully Xiaomi is working on a system update that will rectify all these problems and make them "just work".
