Is screen calibration there in nokia lumia 520?

[Windows Central Question]

My touch is not working properly. sometime it starts typing automatically and sometime touch does not work.

 

[RumoredNow]

There is no Screen Calibration in settings (like where you tap different targets to lock in accuracy for how you touch the screen).

Typing automatically? So the keyboard is too sensitive, yet the screen is not sensitive enough?

Check settings > touch > put sensitivity to "normal" (if it is not) or "high" (whichever is different) and reboot. If that solves your problem, go back to the sensitivity setting you had before and reboot again.

​If your problem does not get sorted; run a backup and do a hard reset.
