I have this phone and contrary to the article about the Bluetooth codecs, it actually doesn't support APTX, I have a BT earphones that support APTX and it doesn't switch to APTX, only AAC and SBC or LDAC only.
The Xiaomi Redmi 12 is an inexpensive mid-range phone that's water resistant and offers good everyday performance. A highlight could include its camera which is fitted with wide-angle and macro lenses - but costing under US$200, is the phone really capable of taking great photos?
