I have a Motorola G4, very similar to the G5S +. I receive updates about every 4 months. I can't speak for the security features though as I do not really make purchases with my phone or even use social media as much. The sound quality is great, the camera is decent enough ( it takes a while to get use to it's draw backs such as : terrible low lighting focus, shutter speed response, and manual focus ease of use). However, for the price you are getting a huge screen with 1080p res, a great cpu that can handle most games and video streaming, and at least 16gbs of storage, maybe 32 now, with a couple of gigs of ram for cache? It's about 1/3 of the price of a Samsung with about 3/4 of the performance of a Samsung. I like mine's a lot.
