Why is my Paperwhite Kindle frozen and how can I address the issue?
Recently, I’ve been experiencing a significant issue with my Kindle Paperwhite—it has been freezing unexpectedly. This problem occurs without any clear cause and interrupts my reading sessions, making it incredibly frustrating. Sometimes, the screen becomes unresponsive, and I’m unable to turn the page or access the menu. Other times, the device just doesn’t wake up from sleep mode. I’m not sure what triggers this behavior, but it’s disrupting my use of the Kindle. I’ve tried pressing all the buttons, and even though I sometimes see a flicker of response, the screen mostly remains frozen. This has made me concerned about the potential causes and wondering if there’s a systemic issue with my e-reader.
