The JollaC I received last week has a weird problem in a specific area of the touchscreen most of the time. It seems to think there are multiple inputs when I only touch it with 1 finger, and that only in a specific area (a horizontal bar almost at the bottom of the screen). The rest of the screen is functioning exactly as it should.

This schreenshot shows a little bit what happens (CSD-tool used with only 1 finger): image description

The 'surround touch'-test seems to work fine most of the time. A factory reset did not help with this problem.

Outch! Get in contact with Jolla Care. They mentioned despite no warranty, they would be helping.

Because this isn't always happening and most of the time it is not a problem for me, I still hope it is a software problem. But thanks for mentioning it, I will do that too. :-)

That doesn't sound good. My (1st gen) Jolla started doing something similar last week, and a reboot doesn't fix the problem. The screen suddenly and spontaneously developed a dead spot somewhere just below the middle where touches just don't register at all. It's very annoying as it makes scrolling very difficult: it either stops scrolling, or more often, thinks it's a press instead of an ongoing scroll or drag event.

I'm not familiar with hardware specifics, but I suspect some of the touch sensor hardware circuits are broken. You might have the same problem, if the problem always occurs at the some coordinates.

I'm worried because I think we can't get a working Jolla/Sailfish phone from anybody at this point...
