3 problems with Inkpad 3

I have Pocketbook Inkpad 3 and it has three annoying issues.

First it had this:
When it wakes up and I continue where I left off, it often messes with the font size. It doesn't keep the setting I have chosen previously.


So, I updated the software to the latest version thinking it might fix it, it now does it still, but not as often as it used to. But after the update I have TWO new issues:

- It occasionally just shuts down while I'm reading.

- It skips pages. For example I am on page 90, when I turn the device back on I might suddenly be on page 60, or 70. It is annoying, if I don't happen to remember what page I was on previously, I need to spend time actually finding the right one.


I am already running the latest version of the software, so that won't help anymore. Also I have tried to reformat the internal memory.

Are these bugs common, or is my device clearly faulty? Is there anything I can do for those, except wait for the next software update and hope it fixes them?

Thank you.
