Xiaomi India — POCO X3 front camera and Speaker not working after new update MIUI Version 13.0.1 Stable

POCO X3 front camera and Speaker not working after new update MIUI Version 13.0.1 Stable. Main camera is OK. But when we shift to Selfie Camera It hangs. I went to MI Service Centre. They told that Main Board should be replaced, which estimate up to INR. 12, 000/-. I approached many service centres, they said that this problem was caused due to latest update of MIUI Version. POCO X2, X3 phones are affected badly due to this update. Many lost their Selfie Camera. Some lost their speakers too. MI should fix the problem. Either they should release a new update which can recover the problem or they should replace or compensate the users issues. Overall performance of the Phone POCO X3 is very good. So we expect a speedy remedy for the issue.
