Hi
Ludo, I can confirm the same. Here my summary of bugs on this tablet.
V1.0.4_V5 (dual OS)- 501 Google services error + not working GPS
V1.0.1_V5 (Android only) – not working GPS + brightness issue
On onda.cn web, 2 new firmwares appeared V1.01_V6 and V1.0.1_V7. Both can be used with 4GB/32GB and 4GB/64GB versions, but there is no description what issue are solved (and what was broken 🙂 additionally). Did anybody tried this firmware already and can inform about results?
thx
Maciej
