Bottom edge of touch screen not responding

So, last week I bought the P2. So far I'm very pleased with the device. Next to the known audio sync issue I ran into one other thing that still bugs me after a week of use: the bottom edge of the touch screen doesn't seem to respond to touch. When I slowly slide my finger from above the screen over the edge of the screen, it immediately picks up my finger, even when only a small part (maybe a millimeter) touches the screen. When I do the same thing at the bottom of the screen, it will only start registering my touch when I'm about 6mm in.

6mm doesn't sound like a lot, but it's enough to make me miss-touch the space bar half of the time. I thought I'd get used to it, but it is still quite annoying... Is this the same for all P2's? I'd like to hear if anyone can confirm this.

Same problem here, it seems that when you hide the on-screen buttons that area is effectively useless. On 6.0.0 and 6.0.1. I have no idea how to fix, but you definitely aren't the only one

Check your keyboard set up. I have hidden buttons and the whole Spacebar is active to touch. Right to the bottom of the visible Spacebar. There is a gap slightly narrower than the Spacebar beneath it at bottom of screen. This does not respond to touch. My advice would be to be a little more accurate with typing :). As there is no way to fix this and keep hidden buttons. Gesture home button, hidden navigation buttons and big battery are best features of this phone!

I wouldn't even have noticed this issues if you hadn't pointed it out. It's present, but it doesn't really bother me too much. Especially since I switched from my G4 which had me miss the spacebar and hit the home button way too often lately for no particular reason. Not having those softkeys is still an upgrade for me ^^

It is software, but it won't be patched. There needs to be a certain amount of space at edge of screen (dead zone) to allow swipe up of navigation buttons but also avoid unintentional swipe ups. They could tweak the size of the dead zone I guess, but I don't see it happening. Alternatively they give an option to totally deactivate on-screen navigation buttons and accept some apps may have issues.... I guess it is a trade off. As I say, I cannot see Lenovo changing it.

The last option would work for me I guess, although you do need the navigation buttons sometimes for older apps that still use the menu button.

i am sure its definitely a SOFTWARE problem, official lenovo forms also has a thread about this problem..


so lenovo would patch up in their next update :)
Ah, found it. They say it's required for the "swipe up" gesture... Seems strange to me, but let's wait for another reponse from Lenovo...

Have u checked through Lenovo app in the phone? Run diagnostic through the app, if any point in the screen doesn't register the touch, you should be able to claim warranty with Lenovo. I had the same problem, and Lenovo service centre gave me a new unit....

That is not the problem. And if you try the touch screen test in the Lenovo app you see the the bottom area of the screen is white and it cannot be tested. What he is talking about is not a hardware error, it's just a poor implementation in software.

Is there anyone in here that have root that have tried Immersive mode? There are apps in Play store that lets you activate this. Does this help the bottom of the screen to register touch?

I understand that there's potential issue with the software as many has reported as well... However it's good to confirm that it is not a hardware issue... In marshmallow, you should be able to test it, it won't be whitish... I tested before when I'm claiming warranty for my previous unit... Same issue, space bar does not respond...
