Mar, it is a real shame all the old content was lost, as I know a lot of us spent a fair amount of time researching and writing out posts. A backup system for the database is now in place, rather than just the files themselves.
The X7s come in a range of slight variations. If you ever look for X7 firmwares online, you'll see there are at least five (six?) slightly different models. We advertised it as having bluetooth, as we'd been told by the factory that this was the case. Once they arrived and customers tried accessing bluetooth, it became apparent that that specific hardware revision didn't have the necessary silicon in place.
The current adverts that mention bluetooth are accurate as we've switched to a different hardware version, and tried to make sure that the factories understand that last minute substitutions for previous SoCs (System on a Chip) used need to take into account missing features. I've tried a few bluetooth dongles with an X7 I have that has no internal bluetooth hardware, but it looks like the firmware doesn't have the required files/drivers for external BT dongles to work.
The Xbox 360 wireless controller adapter for Windows does work in general - see
http://www.droidboxforums.com/posts/188 - assuming it has the same PID/VID.
Use the normal USB sockets, OTG can be used with an adaptor, but we mainly see it in use for firmware flashes (on RockChip based devices at least, like the Q7, X7 series, V9 etc) when connected to a PC. OTG USB sockets on tablets/phones are normally the only type of USB sockets available, which is why you'll sometimes see mention of OTG capabilities/requirements in discussions of Android hardware compatibility.
I've not got any PS related hardware to test my devices with, hopefully fellow customers will be able to chip in with their findings.
If you're not sure whether you've got serious issues with your current Android installation, I'd try a factory reset via the Android Recovery Menu, see
https://droidbox.co.uk/blog/how-to-access-your-droidboxs-recovery-menu/ for the procedure. If that doesn't help, e-mail me (
[email protected] ) with the info mentioned here -
http://www.droidboxforums.com/threads/what-to-include-if-you-need-to-e-mail-us.364/ - as well as what the bottom of your X7 states (look for model names like B351_BT (and variations), AC8350, Q7 (don't blame us, the factory put that one there), EKB311 and EKB311B . From that info, we can check which firmware is the latest for your type of X7.
Re lots of apps not working out of the box, it may well be that there are compulsory updates for the applications, created since the firmware was cooked up. If the apps come from the Play Store, make sure you've enabled auto-updates - see
