My Poco X4 Pro Developed Camera, Overheating, and Charging Issues in 2 Months

When I first bought my Poco X4 Pro 5G phone, there were no issues at all, but problems started appearing shortly after. First, I noticed severe pixel distortion and extremely poor image quality in shots taken with the camera's zoom feature. Then I started experiencing a lot of freezing, lag, and serious overheating issues while gaming.
I've only used the phone for about 2 months in total, and within this short time, the performance issues have gotten considerably worse. Right now, there's also a serious charging problem — the battery isn't charging properly, and the charge level isn't rising correctly. All these symptoms make me think the device has a chronic defect. Even though the warranty period has ended, I don't believe experiencing this many severe problems in such a short time is acceptable.
I haven't yet contacted authorized service or customer support, but along with this complaint, I want my situation to be reviewed and my problem resolved. I am requesting that my Poco X4 Pro 5G device be replaced with a new one, and that I be given a brand-new Poco F8 Ultra device instead. I kindly ask that my request be evaluated and that I receive a response as soon as possible.
