1. (a)2. (a)3. (a)4. A Sweet Love Note: Unfortunately, I am not a user of any Note series Mobile, but as my experience i am the big fan of its S-Pen.As I seen its feature in promotion video,then I thought that one day I must use any Note series...
I think, I visit Service Centre and told them to do my mobile previously Android Nougat Version. Because its much better and prefer to use Nougat than Oreo in almost all sence.
After Oreo update, I also Faced Fast charging issue. i.e, fast charging is not work properly and it charge my 100% battery in about 2-2.5 hrs (without using mobile while charging).
