I just got the tablet and I really like it. I have the BTV-W09 version. When I was on android 6.0 I was able to use the fingerprint sensor gesture and have the navbar at the same time. I updated to android 7.0 using firmware finder, and then had an OTA update to the B351. I noticed that since I updated to android 7.0 if I enable the navbar it prevents me from using the fingerprint gestures, and when I disable it the fingerprint gestures return. Is this a feature or was there a problem with my install? Thanks!
