Add the DUAL CLOCK feature in VIVO phones, mine is VIVO Y83
Hi VIVO customer care,
I'm using VIVO Y83 (model number vivo 1802) , and I don't find any option or trick to add the DUAL CLOCK feature in my phone. I suggest you provide an app or update, and also create a video tutorial for the same, so we can have that feature in our phone too... Thanks
