I think you need to check again. I have that model, and the # is HSG1279, not HSG129.
The model's name is the SN1AT71.
This model often comes with a lot of problems such as those you describe. By Googling, you
can find a number of owners who are unhappy with its slowness and other problems. I have
learned to live with its slowness, but for me a new problem has arisen: I keep getting a pop-up
wanting me to "upgrade" to Android 4.2.2. The problem is, I contacted Hannspree about it and
they recommended I NOT do it. They say the "upgrade" is flawed and will cause even more
problems. Isn't that just wonderful? Meanwhile, that pop-up shows up over and over, interrupting whatever I am working on, sometimes as often as 3 times an hour.
Hannspree says they cannot help me, but they may be able to help you, IF you can reach their Support people. It's not easy, but it can be done.
P. S. For all who may be wondering about this tablet, I cannot recommend it. Altho if you
only want it for viewing YouTube videos and the like, it seems to work fairly well, and the
screen images are quite excellent. But be sure you have a good, strong wifi signal.
