Awesome mobile in this price range.
Configuration is
Android 6.0.1 Marshmellow
RAM 2 GB
Internal Memory 16GB
Dual SIM, VOLTE supported, Direct calling from Jio Sim, no app required.
Cammera 5mp / 13 mp good in my opinion.
Battery is 4100 mAh.
Only one thing is not good in this phone is you can't use dual sim and memory card at a time as it has hybrid sim slot. You have to chose either dual sim or single sim and memory card.
Its support OTG.
Its a good budget phone.
