Hello All, I am new to tablets, I purchased one so I wouldn't have to carry my laptop around at school as often. I have books and large PDF files I am trying to use on it, and it seems to crash the device when I try to jump to different pages, or search within the PDF. Is there a fix to this? A way to downsize the pdf, or anything because the reason I bought my Samsung was for this use, and well it doesn't seem to work well. Thank you for any advice, Im still trying to figure it all out!
