China's WeChat (微信）social platform and Apple are negotiating a 30% handling fee. 
If the negotiation fails, the iPhone 16 version does not support the update of the WeChat APP, but the old version of the iPhone can continue to use WeChat. 
I'm afraid that the iPhone does not support WeChat. China's Android phones can't be used too rubbish, basically "naked", and users' every move is monitored by the background of the evil Android phone. 

I've never used an Android phone, but it's too dangerous⚠️. HOWEVER, CHINA'S 安卓 Android CHARGES 50% OF ALL APPS.
