There seem to be several latent defects in the Samsung Galaxy S7.
- Ghosting - a green/grey "ribbon" at the lower end of the screen, terminating in a totally blacked-out screen with a blue LED showing. many users seem to have reported this and my own died that way.
- The screen was also over-sensitive, worsened by the blue light filter
- Slow charging
- Weak signal reception on LTE and wireless
- Bluetooth connectivity erratic on Windows 10 Pro but perfect on Linux, on the same laptop
