Your tablet could be possessed by a poltergeist. Perhaps having a Catholic priest perform an exorcism will cure the problem.
Seriously, the problem may be related to your tablet's touch settings. Go into Settings. Select Accessibility. Select Touch & hold delay. Select Medium (Short is default).
changed it... i do hope that it fixes it cuz its really annoying ill observe it for a day thanks! Btw.. to some point i thought that my house/tablet was possed xD
