I had a major kindle crash not too long ago.
And the cause of it was something I would have never imagined.
It was the program/app that controls my smart control unit! This caused my kindle to crash because I did not guess that the smart control equipment app required a more up-to-date kindle. I have an older kindle that simply could not handle the technology that the smart control equipment app for my central heating & a/c has. If I had study the manual more close I would have known that. But because I didn’t the smart control equipment app caused my kindle to crash & also cost myself and others a few hundred bucks to have a kindle tech come & rescue the kindle to make it operational again. So i want to tell most people that if you have an outdated kindle, do not put the program & app for the smart control equipment on it; Put that smart control equipment app on your iphone only or an up-to-date kindle. If you have a new kindle it may be ok, but just study the instruction manual about the smart control equipment because that will tell you if your proper kindle could handle it or not. In the future I must study more carefully & not be in such a rush to get things going, had I done that in the first locale I would have saved myself a few hundred bucks on kindle repair. I’m just ecstatic that everything was able to be rescued & fixed!
