Just purchased a chinese branded F900 Allwinner A13 Android 4.0 9 inch tablet and finding some potential issues...can any experts help me out? 1. The internal microphone volume is very low. Tried recording video and voice and i have to yell into microphone and still very low volume. I have turned up volume to max but still not help...is there a solution? 2. Google Play/Market is pre-installed. However, downloading an app is not working. Its just keeps on "downloading" without ever finishing or installing even for very small apps. Wifi is connected and working, cleared cache, re-start...etc. but problem continues... 3. Connecting to wifi takes quite a while but eventually it does connect. Its take a very long time even when i set up the wireless router right next to tablet. i have powered off, reset, removed caches...etc. but still takes a long time (maybe 5 to 10 mins). When I use my netbook or Ipod touch with the same wireless router the connection is almost immediate...is there a solution? Any help/advice you can provide is greatly appreciated!!!
