First of Tablet info :
Model number : Micromax P275

I dont know anything about android
now the issue is that the screen keeps randomly jerking and there are random touches that happen which will open apps and close apps randomly. this happens after few minutes since Tablet turn on. When these things happen i cannot do anything. even if i try to power down by pressing the power key the dialog box disappears because of this random behavior.
i observer this behavior mainly when i travel in bus. so i'm thinking that the vibrations are affecting the accelerometer and thus causing the random movements. When i'm in a stationary place i rarely see this issue, but it has occured.
now i disabled
2)Disabled all options in Developer options except Force hardware rendering.
the system update will happen and i cant turn it off(atleast i dont know).
my main useage in the Tablet are 1) pdf reading 2)videos 3)small c programmin(using CCtools).
please help me with this issue. its is very very frustrating. last thing,i brought this device 28 days ago. also i would like links on reinstalling android.
