Proximity sensor and fingerprint not working via OnePlus 7T Pro McLaren Edition

  1. I1580561675112 , via OnePlus 7T Pro McLaren Edition , Jul 5, 2020 :
    Yesterday my proximity sensor stopped working and today my fingerprint stopped working. I tried changing fingerprint but after some time it again showed not recognised. Any solution to it. My phone is oneplus 7t pro McLaren edition bought in march start and still is in warranty. As lockdown is going on in Navi Mumbai no one picked call in service center. Any solution for it .? Will phone reset will sort problem?
