I had a kindle for a month and it wouldn’t charge so we sent it back to Amazon. That kindle did not flicker on every page. They sent me a new one. It flickers every page. I read that this is normal. Can you tell me if it is a design, a flaw in my opinion, or is my kindle broken again. Disappointed. If this doesn’t change I’ll go back to reading on my iPhone. It is very distracting.
As codynarbs said above, you can set the Kindle to refresh less often but the screen does need to refresh periodically in order for the display to work properly.
Kindles (and other ereaders) use an E Ink screen. E Ink is very different to the LCD screens used by phones and tablets which refresh and update constantly - every frame in a video, every movement in a game, every new character you type in a text message causes a screen refresh - this is one of the reasons why batteries on those devices last such a short period between charges.
E Ink refreshes much less often (helping you to get much longer battery life) and when it does it's refreshing what's effectively a static 'image' of a screen full of text which is why it's so much more noticeable. You can change the frequency so that it refreshes every few pages instead of every page but you can't eliminate the need to refresh the screen.
If you google 'why do e ink screens refresh' there are some very good articles which explain this in more detail.
