I'm using jio and i'm unable to make calls and receive calls from my nokia 7 plus after june security update, bcoz there is some bug in that update.
No one posted a solution for that bug and surprisingly there is no response from nokia regarding this buggy update.
All Nokia 7 plus users please ask nokia cc about this and write emails to the nokia care.
It is non sense that they made our devices dead by releasing a buggy update where we can't use the basic calling feature of a mobile phone.
yes, i tried changing sims and tried reset network setting and finally factory reset also, still not working. Not only me many people tried all the troubleshooting and nothing works.
