[Resolved]  Vivo Mobile India — vivo v9 hanging problem

Address:

Nellore, Andhra Pradesh, 524126

I am using vivo v9 from 10 months onwards recently it shows software update then i update my mobile to new version from then onwards phone was hanging too much. I am very unsatisfied with vivo so please do needful, whenever i take calls it was lagging for every call it was too frustrating. First time i changed to vivo but this is the last i think so.
