I bought a mobile phone in ZTE Hechuang mobile phone franchise store. Please refer to it for me.

Worry is unnecessary! It's cheap to buy things in a store! Feel free to open it boldly, as long as it can be used normally, there is no quality problem! Some stores also support unconditional return! If it is activated, it will not be refunded! That means you may have met a liar! Buy it at a famous shopping mall next time! I didn't pay attention to whether the mobile phone I bought in Suning was sealed!
