You may try to use JioVoice app to use VoLTE service, however using Jio SIM is not recommended on Z1 as it seems most users are having problem with Jio SIMs on Z1....
I charge the phone and unplugged after full charge and play a music and it got off and start to vibrate and off. When I tried to switch on it still shows a lines on the screen and vibrates. What troubleshoot can be done to rectify the issue?

Really disappointed with this phone. First the fingerprint sensor stopped working after 6 months. 8th month and the power button has issues. 10th month and the home button behaviour is ridiculous. 11th month and you notice the screen lag for first time. 12th month power button and home button stop working. A year has passed and you now go to settings to enable the tap screen to wake up and double tap on task bar to lock because only volume buttons and soft buttons are working. A month into the 2nd year and phone keeps restarting for 4 hours and then when it you were happy that it is up, soft buttons have stopped working, 2 weeks after the dies and you throw it away because you don't know how to switch on a phone where power button is dead. Yah, I am lazy to go to a lenovo center 20 kms away fom me

Zuk z1 - switch off when i go call sim no 2, the same issue for receives call after end time going to switch off again. Incase any missed call for sim 2 mobile hanging on touch screen not working. Then few second hold power button and restarted. Last few day's like that problem I'm facing for my zuk zi I'm totally worried.
Port your zuk z1 from cyanogenmod to zui . Its working owesome. Everything is smooth. No root required for this solution
Anonymous, 17 Jun 2017hi!frds i want know one detail about lenovo zuk z1. can it use jio simYou can use Jio SIM for data, but for calling - you need to install Jio Voice App. Unfortunately - it seems it causes problems with the phone, based on Zuk support forum on Lenovo site...
