Bibhu@89 , via OnePlus 7T , May 14, 2021 : I am a loyal customer of OnePlus & I am using Oneplus 7t now. On April month I have received Oxygen OS-11 update in my Mobile. After installing the update, finger print sensor in my device is not working. I have contacted customer care through mail in firstname.lastname@example.org & also called to their customer care on 18001028411. After some days I have received reply from their customer care for the remote flashing of my mobile & accordingly I have downloaded the required files for remote flashing. After that they are not performing remote update & not replying to my mail after several follow-ups. I am frustrated with the service of Oneplus. This type of service is not expected from a brand like Oneplus & I recommend all to kindly think about their after sales service while buying a Oneplus Device.
