The pictures are located in pictures->screenshots on the internal sdcard.
Connect it to your PC and check your pictures.
I have sent a mail to firstname.lastname@example.org yesterday, I also send a mail to ramos-tablet (the webshop I bought it in)
Have you flashed your tablet, mine was delivered with this firmware it was shipped 31/12.
There's a hugh forum in chinese www.ramosfans.com and I think they describe our problem, the thing is, how can I upgrade it when I can't see anything?
What I also noticed is that all H/W acceleration is turned of, no idea why, maybe heating problem. I loved this tablet, and I hope its just a firmware problem I can fix at home.
I'm trying to flash the "original" firmware. I will talk to you later.
I'm going to extract the firmware to an external micro sd card and then put it in the tablet. With the power and the "+" button you get into the "download mode". From this point it works on its own. It will take about 4 - 6 min.
I hope it works, wish me luck xD
