I currently use a 5.5" Windows 640XL and wish to try an Android replacement. I have lots of Windows experience, little Android experience. I do have a Samsung Tab 4 8.0 tablet that I recently purchased and like a lot. I need compatibility with AT&T GSM (Consumer Cellular) and a 5.5" or 6" screen. I would like to stay south of $150, so will probably have to buy refurbished or used. I would like one that has a good record for updates and a minimum of bloatware. I'm not hunting all the latest bells and whistles, just a dependable and reasonably priced replacement.
