Hey. I recently just got my JXD S7800b in the mail from DinoDirect and it has no hardware flaws that I can see thankfully.
Unfortunately, some of the apps don't work. Whenever I load a mail in the gmail app it just crashes. Whenever I load up the browser it flicks on screen for a few seconds and then it's gone. If I try to use the voice search, it will load long enough to say speak now then go back to whatever screen it's on.
Even some games I downloaded from Google Play are hit and miss. I'm really at a loss at what to do.
