Hi folks, I'm new to Koreader (which helped my decision to buy an H2O) but I'm having serious trouble getting it to run reliably which is a pity because the screen is awesome and the PDF features in Koreader are as well... I've a couple of PDFs (some Adbobe ClearScanned, some just plain Text PDFs) and I still have to find a way to not make Koreader crash at some point, which is really annoying because I lose a lot of highlights most of the time... Found Reflow without scrolling to be the best mode for me (in terms of reading) but the crashes just happen regardless, even in completely unchanged PDFs.
Another thing that I found was happening to me very often is that highlights wouldn't appear. Most of the issues are resolved with rebooting but that only gets me going for so long until Koreader randomly crashes again without warning...
I've read that it may have to do with an unreliable internal SD card but I'm reluctant to change it because I think it would mess with the waterproofing... Are there any workarounds or changes I could make to the software to get Koreader to run more reliably for my PDF reading needs?

Edit: this is the fourth time so I'm adding this: I get freezes in Nickel after using Koreader that I didn't have before. Upon reboot I have to re-set my language and all my Pocket account data and Wifi password are deleted (but not the Kobo account).
Another thing I've noticed: after using Koreader and starting Nickel, the five square startup dots are scrambled and all over the place...
I think there's something seriously wrong with my Koreader (and I have the feeling that it's actually getting worse with every crash or failure (is that possible?).

Edit2: right, and I almost forgot: Im running koreader-kobo-arm-linux-gnueabihf-v2014.11 (stable as well as latest nightly) on 1.13.1 (unpatched) on KSM 7 with patch...

Is there actually a reliable way to use Koreader on the H2O, a sort of to do list of what is to be done to avoid crashes? Another really stable release maybe?
