Ok, this is weird. I was reading a MOBI/PRC book on my Aluratek Libre Pro (2+ years old) and noticed missing words. Naturally I thought I'd gotten a poorly proofed copy but when I checked the file in both MobiReader and Kindle for PC, there were no errors, the full text was there. Adjusting the font size on my device did not resolve the issue, nor did deleting the book and copying it back again. I managed, finally, to make it more readable by taking it into Calibre and converting to Mobi again with heuristics on. That restored the "missing" words but made for some odd line breaks and spacing. The book in question was not previously converted, I only buy Mobi and Epub books unless those formats are not available, so I haven't a clue why or how this happened. Also, I have noticed the same thing happening with other books, "missing" words and bits of sentences/punctuation where previously they looked fine -- and still do, just not on that reader. Naturally I checked the SD Card but found nothing wrong with that and my battery was full at the time.
I have noticed lately my reader does not hold a charge as well as it originally did, also is not quite as reliable about how full the battery actually is -- the bar has at times gone from two-thirds to empty in less than a minute after turning it on and I find myself recharging more frequently. Is this a sign the poor thing is dying on me or is there a (hopefully) simple fix?
Oh, forgot to mention my firmware is also the latest version but I see they haven't updated it in about a year.
