Help Recognize my Tablet

Hello All,


The problem is that I am new on this platform so I cant start a new topic so please forgive me that I am posting under this current one as it best fits my own problem too.


I just ordered for ACER tablet from a Chinese store and after transferring of money, he said his bank removed some charges and sent me a Chinese based model. The one he sent me... All that was written on the pack is MID Android 10" Tablet PC Android 10-inch High Resolution. But I have got issues with it...


PROBLEM


1. The screen is not well calibrated... I think because when it is not plugged to anything, along a line on the screen, I cant type anything, if I need to type a key on that part, I have to move my finger a bit to the left so as to be able to get precision.


2 Whenever I plug it to power or computer, the screen gets distorted and I think that is because of the current going over it.. but y?


3. I cant install some other applications from Android Market because it cant detect his model I think? or cos of the ROM... Like Faceboon, Twitter, Instagram amongst others.


Using Quadrant Advanced, I have the info below;

So please is there any way I can rectify the screen blind problem (PROBLEM 1)? Any better rom I can use that will work with it better and save memory? How to save company firmware, how to save present rom... download a new firmware and majorly..... HOW TO RECOGNIZE THIS THING!


Please help is needed.


Thanks all in advance.
