Hi all sifus, I have just bought a Xiaomi 3S from lelong.

Questions:
1. I noticed that the box runs Kodi v16. Is there a way to upgrade Kodi to v17?
2. It does not have Google PlayStore.. Any way to install it ourselves?
3. My movie streaming (e.g., either using Exodous or Phoenix) on Kodi v16 only lasted less than 4 minutes. Has anyone encountered the same bad experience?

Thanks
