The samsung brand was very famous for hanging problem in present time.
In samsung grand series of each and every phone is hang problem.
I have also buy samsung galaxy grand.
This phone is more hang and less use.
Than after that I buy another phone samsung galaxy grand prime.
This phone was very famous for selfie purpuse at launching time but after some months this is also hanging problem create.
So, my interest in samsung brand is finished.
At present I use coolpad note 3.
This is much better than samsung.
