Hello, everyone. Since is going to be long, I apologize in advance (and also thank anyone who reads to the end). For the past six months or so I've been having a weird issue with my Kobo Aura H20 edition 2. Let me be specific:

I bought it new directly from Kobo Canada on July 2019. Up until, say, January this year it worked flawlessly. Then one day I was reading and when I swiped to the next page I noticed the image was somewhat blurry. I thought nothing of it, but then on the next page the issue got worse. It's hard to describe, but it seemed to insert very thin vertical lines all across the screen. The effect looked like the text was "dripping", so to speak. After a few more page swipes it got so blurry as to be unreadable, and then the top third of the screen got locked in a solid image, and only the bottom two thirds of the screen would refresh on every page swipe. At this point, the part of the screen that was still refreshing wasn't showing the "dripping" effect anymore, but the whole page was compressed to fit that space, sort of like it had been forcefully resized, so the text was still unreadable.

After a reset, it went back to working properly. But then some time later it happened again. I had to let the battery run completely dry, and the screen would still show the upper portion locked (I'm attaching a pic for reference). Only after several days of the device being absolutely out of power and unresponsive (to the point that turning it on will not even try to refresh the screen and display the "no battery" message), the screen will eventually restore itself to emptiness, and then I can plug it in for a charge and keep on using it until the next time this happens.

I've gone through this whole cycle about 4 times already, and frankly it's extremely annoying. Just last weekend I was reading, turned the Kobo off and left it to do something else, and maybe an hour later when I got back to it the screen was in the upper-third-frozen state.

Some more clarification: the device has never been hit, dropped or physically mistreated in any way whatsoever. I bought the sleep cover with it and always used it. Never applied any pressure to the screen or anything like that (and besides the fact that the screen eventually fixes by itself makes me think this is not a broken hardware problem). Sending it back for warranty is out of the question, maybe I could've done it sox months ago when this started happening, but I bought it in Canada and took it back home with me (I live in Argentina) so sending it over mail was not an option anyway.

Finally, questions: has anyone else experienced this problem? Does anybody know if there is anything I can do to fix this for good? Maybe some firmware hack or something? As far as I remember, the Kobo is up-to-date firmware-wise.

Thanks a lot in advance!
