My phone is letv for that I need to using jio4gvoice during jio phone call and incoming call. And waht is my totally experience till now let discuss.
I finally installed this app when It was new launched I got around 30 times update in playstore. This application totally running every time in background if the user remove from background then he doesn't call to anyone and he can't get any incoming call. When It running in phone background firstly he used lots of RAM then He used phone battery by little bit one time user's phone get switch of if the user do mot charge the phone.
After that this app most of time creat lagging of phone, and now in this app user seen ads banner of jio related.
During running this app mobile got heated.
My opinion : please if it possible take a VOlte phone if ypu want to use reliance Jio.
