Android os problem.

[Help me plez]

I have recently received a Texet tablet with android on it. It is not unusable because it does random things. One part of the screen is unresponsive and it randomly clicks stuff. Quite often it lags out and is not responsive. I want to try to get either newer version of android on it or Ubuntu through USB. I could really use some help.

Sounds like you have a defective tablet. A new version of Android or Ubuntu isn't going to resolve these issues.
