Mind tell how the problem.

Wow, glad to hear that! 

Have you encountered any, or even the slightest noticeable drop in the sensitivity of the touch screen?

Here is one of the several videos I found displaying such issue:

In this video, the left vertical area of the touch screen became unresponsive (the area was shown through the paint joy apps at 0:51).

The comments under this video, comments on both chinese and english Lenovo forums and comments on gsmarena have all mentioned similar issue. Some had their lower right area became unresponsive, some lower left etc.

The more I read and research, the more I am convinced that this isn't just an isolated case. 2 years ago I had a Lenovo A369i, of which the touch screen died after several months of use... and now I'm even more concerned.
