Chaina

Purchased vivo y55s (Model number - vivo 1610) in 2017 in Solapur. From last few months onward, it has started suddenly shutting down without any reason. Then it shows black screen with vivo logo and don't start at all. Then i need to long press power button to switch it on. Since last few month, it definitely shuts down at least twice daily without fail. Sometimes, during an urgent call or some work in app, it switches off and important call or work is lost. Sometimes it automatically turn on but this time not able to use Wi-Fi hot-spot and while playing YouTube video or what's up video it shows black screen and only voice is audible.
