Samsung Galaxy s8 or s8+ are awesome mobile phones working fast capturing awesome. Best phone for this year but the mistake made by the designers of these two phones that they have provided finger unlock at the back although it is not so troubling but the main point is that they have provided it next to the camera lens. hence it made a lot of problem to use many times finger touch the camera lens and then it need to be clean by a soft cotton. The mobile works awesome but the problem is that the designer should provide the finger touch unlock at the middle of the back just like google pixel then it does not need to any advice or reviews. the s8+ is so large in handling the 2nd problem is to kept in hand then touch the finger unlock the fingers need to be large for that when you kept the phone from middle then it touched easily but not when you kept from downward although I am giving it 5 stars because it is awesome. Thank You
