Lenovo Tab 4 10 Plus touchscreen issue

2018-03-15, 19:31 PM

Hi, I have a Lenovo Tab 4 10 Plus (TB-X704L), latest firmware:

 

I noticed a bad touchscreen behaviour when I tap or swipe in the top area (near the top edge - where there are the 2 speakers). If I try to draw a line slowly, it results often in a dotted or strange line. This means that, for example, when I scroll a pdf i get a very uncomfortable behaviour. I made ad ad example:

 

It happens also to a friend of mine with the same device and configuration. It happens with every kind of app.

 

I tried factory reset and wipe cache, but the problem remains. Do you also notice that problem? Did you solve it in any way?

Thank you.

I had the possibility to contact various people that own this tablet. Anyone has problems, so my device is a defective one and I contacted my local support shop to receive under warranty assistance.

I will update this topic, just to inform you.

I received (after a month) my tablet from under warranty repair service.

They changed my screen with a new one, they wrota "changer screen and passed gerenal testing" but the problem is still here.

So, I advice you to avoid buying a Lenovo tablet. Worst experience possible with an electronic device.

Hi Nicola, I checked my tablet screen, drawing lines and scrolling pdf files fast and slow and on every edge of the tablet (the sides where speakers are and other edges). The behaviour seems to be normal and very much the same on every edge. at least I did not notice any strange behaviour.

Lenovo repaired it under warranty two times. First time they changed the display, second time they changed display and mainboard. Unfortunately, the problem persists. I did not try for the third time because I don't have time to bring it to che assistance center.

Good luck!
