Fosnes,
You can try going to Settings->Display Settings->Render Preference and change it to "Speed" instead of "Quality". That should use less RAM I believe. I have tested on a device with 4 GB of RAM, so I don't think that's the issue. I'd be happy to test with one your PDFs if you want to send it to mike@zubersoft.com. Different PDF libraries can have drastically different results with processing PDFs. It's possible those PDFs are loading very slowly with the library used with the "Quality" setting. Apple provides a PDF library to developers on the iOS platform, whereas Google and Microsoft do not. So results are going to vary between the PDF processing on iOS versus other platforms.
Thanks,
Mike
UPDATE:
While loading various small PDFs on my machine, I never see RAM usage go much above about 160-170 MB. I definitely think there is an issue with those PDFs that MobileSheets isn't handling well. Please send me one for testing if you get a chance. While loading a 448 page PDF (a real book) that is about 120 MB, I see RAM usage go up to about 320 MB. If I switch to the "Speed" PDF library, it drops to about 194 MB.
