Is it google maps v9 or higher. You're not allowed to use v9 or higher because it is most likely compiled with NEON support. NEON is a cpu feature we don't have but should. It was standard at the time the tablet was produced. Without some very clever hacking, you'll have to downgrade to v8.(whatever the latest is).
Only things left:
- Google Now launcher does not like 'OK google'. Read that was a bug
- In Settings, when you go to Performance tab, then a different tab and again go back to Performance... the tab fails to load. Stays as a blank tab.
