I have to ask because my mother in law just called to tell me her Kindle wasn't doing anything. She couldn't unlock it. She has a Kindle Fire HD 7 2012 which she bought 4 months before the HD 7 2013 came out.
Are you ready for this? She has never restarted her Kindle since we set it up for her.
That's right she has never restarted it. She didn't even know it had buttons.
It doesn't have the latest firmware even. So you do the math how long that Kindle has been going without a restart and do you want to know how many tabs she has had open for how long? Over 25
It looks like me explaining bookmarks to her last year failed. I have to say I am impressed with the 2012 version of the Kindle Fire. Very impressed it could survive without a lock up for that long.
After wanting to bash my head against the wall because my mother in law just refuses to follow simple instructions. We talked to my Father in law and we got it to restart by holding down the power button she swore up and down was not there. So it's all good now and her Kindle is working again.
