My Asus Zenphone 2 dont have Volte so I installed Jio 4G voice on my device. From the beginning the started consuming lot of RAM and my battery stated to drain faster than it used to before. I would have ignored these problems if I would be able to make free voice calls and send free SMS but Jio is so bad that my 90percent call drop. Even the Sms used to take 10 to 15 mins to send through this app. This app doest work without internet connection but sometime even after being connected to internet I was unable to use this app. This app also crashes a lot and sometimes don’t responds.
