Hi, I'm very new to Android based devices and recently bought a Lenovo Tab M0 plus. I got it to give me some technical interest to keep my poor old brain going, it may be too late some would say. Initially I worked as an electronics development engineer and after after about 10 years moved into IT support. I then went to work as a field service engineer for a very big computer company. I predominantly worked on hugely expensive UNIX systems and gradually migrated to Intel base products as the market changed. I retired 4 years ago and have been tinkering with PCs, GPS devices and RC models. I have gotten to grips with Windows 10 and recently built a stupidy fast PC that can boot from cold in about 10 seconds. I sit there waiting for it to do something only to realise that I've blinked and missed it. I have recently started dabbling with Android devices. I'm more interested in the technical aspects than actually using them. So be prepared for some obscure technical questions.
