Forma: touch screen unresponsive

franklekens · 09-21-2021, 10:26 AM

Suddenly my Kobo Forma won't respond to any touch screen actions anymore. I woke it up after a few days of inactivity, battery at 67%, the sync button started churning and it didn't respond. I thought it was because the syncing was hogging resources or something like that, like on Windows. I made it sleep, woke it, same thing. I restarted it, same thing.

Then I waited until the sync button wasn't churning anymore. But now it still won't respond. What it looks like is as though all touch screen functionality has been lost. I can switch it on or off with the button, and I have a hunch that if I'd left it with a book open instead of at the home screen the last time it still worked, the forward/backword buttons might still work. If I connect it to a computer I do get the question 'connect or just charge'. I just can't tap any of the answers.

Is this a known failure of the device after a while or in certain circumstances? Is there a known remedy?

Hm... Well, the spell is broken.
I left it on the charger for a while, switched on (just on the off chance it needed to do some updates or whatever). I took it off, still no dice.
I restarted it again with a long press of the button, and suddenly it responds to the touch again.
Oh, another symptom was it didn't respond to the gyroscope, i.e. didn't flip the screen when I held it upside down, as it's supposed to, when it was in that half frozen state.

But now it seems back to normal.
Anybody ever seen this?

I've had the Forma and other Kobos lock completely. The fix that has always worked for me - hold power button down for about 30 seconds. Eventually it will do a hard reset and reboot the device. After that they have always worked fine.

Needing to reboot a Kobo is not all that unusual.. but in your first message, you explicitly say "made it sleep, woke it, same thing. I restarted it..." which let me to assume you *had* rebooted it..

How exactly, were you making it sleep, and what was different about restarting it?

I don't know, I just don't understand. All I did was press the button in the side briefly to make it sleep or wake it from sleep, and press it longer to reboot.
It's all a bit mysterious, but it does seem to work again.
