I just purchased a Kindle Paperwhite, 10th generation, and so far I really like it. Question: when I tap on the screen to go to the next page, the screen briefly blinks black with white text. Is this normal? Is there a way to stop this from happening? Thank you.
Yes, it's normal (Google 'how does e-ink work' for an explanation). You can adjust the refresh rate somewhat. You can set it to do a full refresh every page turn, or a partial refresh every page turn and full refresh every 5 or 6 pages. Try both and see which you like better. Settings > Reading Options > Page Refresh.
You probably wont' notice the page turn flash after a few days.
