Vivo Y55L is the best phone, I have gifted my younger brother. It has a awesome battery life, with no problems like hang. It has 5 megapixel front camera and 8 megapixel primary camera. It is good for video calling and selfie also.
Secondly it has 2gb ram the phone never hangs. It has a multitasking screen. You can use two applications in one screen.
And finally it has 2 years of warranty, which is mindblowing. Any other brand never gives warranty more than 1 year.
