Thanks for all responses. That is surely useful to know.
I'm only looking at flagship phones and not budget phones as my priority is the camera performance, and only flagship phones have the best cameras. The price of flagship 4G phones are currently significantly lower than flagship 5G phones so there's the advantage for me. For instance the Huawei Mate 50 Pro which was launched just 9 months ago at RM5.2k has now dropped to about RM3.6k.
