Hello friends, nokia 6.1 plus have gifted by my friend on my birthday. I used it for only six months and after I sell it to a person by the reson of many problems. I have faced with many problems. all first problem of speed on continue use. guys, they all problems is that slow battery beckup, problem with display on continue using after few months or one year letter, sound quality becomes bad, it’s camera is not smart it’s normal camera, in some cases it’s speaker ingerd after some months using. so I think that if you thinking about nokia 5.1 plus, stop it and ignore it.
