[Windows 8 General] suicidal.banana:
Both of these prolly relate to Windows update deciding things for us, which pretty much always fails because Microsoft obviously doesn't know a whole lot about Chinese hardware, for me, the camera problems only started after installing a good number of updates (50+) and the black screen issue after i manually updated the driver, it could be that yours has had windows update run on it before you received it, which would explain the persistence of the issues, just to be sure, check the two 'tutorials' below, its how i solved my cameras and black screen issues.

- To fix the camera, uninstall the camera drivers (do it one at a time for an extra failsafe to help you set up the proper driver for each when re-installing) reboot and reinstall, more detailed description below:

0] Download the driver package from the PIPO site or the first post in this topic to your PIPO W3 and extract it somewhere where you can find it

1] Rightclick the bottom left corner of the screen and go to 'Device Manager'

2] Go to 'System devices', rightclick 'Camera Sensor OV2722' and then Uninstall

3] Make sure you check 'Delete the driver software for this device' and then click OK

4] When its done, restart windows 8

5] Go into 'Device Manger' again, look for an 'Unknown device' in the 'Other devices' section, and double click it to install a driver for it

6] In the window that pops up, choose the second option (sry not on win8 atm, but its something along the lines of "i have driver software" and/or "let me choose what driver to install"

7] Finally, when your given the option to select a driver directory, browse too <DRIVER PACKAGE>/camera_8211/ and click OK

8] Now it should install the proper driver again, after this succeeded, repeat the exact same steps for the 'Camera Sensor OV5648' (uninstall the driver, reboot, the lot)

9] Both camera sensors should work flawlessly again, no longer giving BSOD's when you use the win8 camera app

- To fix the sleep-created-black-screen issue, you will have to roll back to the graphics driver that came with the tablet, sadly none of the Intel graphics drivers released after that seem to play nicely with the PIPO, for this you will (again) need the PIPO driver package, from the PIPO site or the first post in this topic, another short guide below (now assuming you know your way around a bit)

0] Turn off WIFI for a bit, to make sure windows update doesnt go and decide on a driver for you later on

1] Go to device manager

2] Pop open the 'Display adapters' item, rightclick 'Intel(R) HD Graphics' and choose uninstall

3] Again make sure you remove the actual drivers from the system aswell, by ticking the 'Delete the driver software for this device' box, then click OK

4] Restart

5] Go to where you unpacked the driver package, into the 'intel_W3/script' directory

6] Run the 'Install_Graphics_Driver.bat' file in that directory as Administrator (dont forget to do as admin!!) and then reboot again

7] sleep-created-black-screen issue resolved!

Now, there is one thing you can do to get slightly better graphics performance, and that is mess with the amount of video memory assigned to the IGP, ive given a short rundown on how to do that here

Hope this helped! :)

==============================

Small update about my W3, based on input from Banggood ive given it too a local 'fixing' shop (the kind that fixes iphones and sammy tablets) with the question if they could open it up too see if everything inside was properlly connected, and sadly, it was, so ill prolly be sending this tablet back to china to get my bluetooth fixed :( will keep posting updates as things unfold, also been pondering to contact PIPO directly (also cuz im still 85% sure this is some knock-off keyboard, even though Banggood said its not)
