Is that the latest Rom you can have on the tablet?

Try Updating the tablet to the latest rom could work my Galaxy S was taking ages to load the gps and with a new rom I installed it went a "bit" better , but just a bit

Let me know the model of the vimicro tablet so I can look for the latest rom or maybe there are custom roms for them too

I have the same problem.

My device:
Handphone Hisense E860
OS: Android 4.0
Resolution: 480x320
GPS: AGPS

Softwares:
iGO My Way,
Sygic,
Faster GPS
GPS Test

Sometimes, it's quick enough to lock to 6 to 10 sattellites (only 3 minutes need to lock), but sometimes until 1 hour no sattellites at all even I bring it in open clear sky.
I've adjust GPG config, and the problem still persist.
I've also use wifi (wiper=ON) and Data connection ON, but still many times fail to lock to sattellites.

Please, anybody have any idea to solve this problem?
