My device poco X3 was working fine before poco released a new update of miui 13.After updating my device it started to have problems with the camera app and some days later speeaker also stopped working. After taking it to the service centre, they told me that many customers are facing this issue and the motherboard needs to be replaced for the same. They are charging me around Rs9600 as the repairing cost but there was no damage caused by me to the phone whatsoever. Upon reaching the customer care they are saying as the device is out of warranty they can't help me and telling me to deal with the service centre. Clearly the problem happened because of the update rollover by POCO (it being promised to provide 2 major and atleast 2 years of stable security updates) and as the problem arosed after the update I demand free repair. I have seen many cases like this online: 1.https://www.consumercomplaints.in/poco-front-camera-and-speaker-of-poco-x3-is-no...⇄ 2.https://consumercomplaintscourt.com/poco-x3-front-camera-and-speaker-not-worki...⇄ 3.https://consumercomplaintscourt.com/poco-x3-camera-and-speakers-suddenly-stopp...⇄ Not only with this phone I have seen that poco phones are always having some or the other problems after updates(poco x2 camera issues, poco x3 camera and speaker issues, poco x3 pro phone dead issues) Last year poco provided with free repair to poco x2 users because of the fault in its software leading to the damage hence I demand the same with my POCO X3.
