WeChat has been unusually chatty about itself this month. Three separate updates, a rare peek at team size, and an official explanation for a feature everyone complains about. For an app that usually just drops changes in your lap, this is practically a press tour.
The HarmonyOS push is massive
On May 14, Tencent VP Cai Guangzhong said at a Shenzhen conference that WeChat has dedicated 800 people to its HarmonyOS version. That is roughly half of the entire WeChat client development team. The scale is wild. They have shipped 21 major versions and over 199 minor builds since launch, averaging about one minor update every two working days.
The latest stable build for HarmonyOS is 8.0.17.36, released on May 6. Users on that version are getting features like contact avatars in message notifications and the ability to chat with Tencent’s Yuanbao AI assistant inside WeChat. The Yuanbao integration is still gray-test, so not everyone sees it yet.
Why the urgency? Huawei announced on May 14 that HarmonyOS 6 has crossed 60 million active devices. Huawei consumer chief He Gang said the broader HarmonyOS ecosystem is targeting 100 million devices this year. WeChat cannot afford to be the app that lags on China’s homegrown OS. The 800-person team is Tencent’s way of saying they know that.
Why the 2-minute recall limit exists
On May 22, the official WeChat account published a post explaining why text messages can only be recalled within 2 minutes. The reasoning is simpler than I expected. WeChat says most people read a message within 2 minutes, so recalling after that just creates the awkward “I saw it, why are you pretending you didn’t send it” situation. The 2-minute window is meant to function like saying “scratch that” in real conversation.
The post also clarified that files get 3 hours instead of 2 minutes because people naturally read files later. You might send a PDF at 2 p.m. and the recipient only opens it after a meeting. A 2-minute limit would be useless there.
What WeChat did not mention is that unlimited recall would let users rewrite conversation history. Loan requests, work assignments, promises. The 2-minute rule is partly a trust mechanism. Once the other person has probably seen it, it stays.
One small quality-of-life fix: you can now recall an entire batch of forwarded messages at once, not just one by one.
iOS is testing carrier-based login
Some iOS users are seeing a new “log in with this phone number” option on the login screen. It uses carrier gateway authentication, so if your SIM is in the phone, you tap once and you are in. No SMS code, no password. The feature is gray-test only right now and requires cellular data to be on.
This is not new technology. Apps like Taobao and Meituan have used carrier gateway login for years. WeChat is late to it, probably because they are paranoid about anything that bypasses their own auth flow. The fact that it is finally arriving suggests they have worked out whatever security review was holding it up.
Combo payment is rolling out
Also in gray test on iOS and Android, with HarmonyOS following: you can now split a payment between WeChat balance and a linked bank card. Previously if your balance was short, you had to top up first or switch entirely to the card. The combo option removes that friction. Tencent customer service confirmed the flow: open the card selection page in the transfer screen, tap the “combo payment” button in the top right, and set how much comes from each source.
Elsewhere in the ecosystem
Douyin is cracking down on blind box sellers. On May 21 the platform posted new rules banning opaque probability claims, off-platform redemption, and point-ranking systems that look like gambling. Penalties range from product removal to full store termination. The move targets the “9.9 yuan for a guaranteed iPhone” streams that have been all over live shopping.
Huawei showed off its new music creation app, Yinyuejia, at a May 22 event. It includes 200+ instruments, including digitally recreated Tang-dynasty Chinese instruments like the curved-neck pipa. The app splits into a “concert hall” for playing and a “studio” for composing. It is clearly aimed at GarageBand users on iPad.
And Canon became the first printer brand to integrate with Xiaomi’s Mijia app, adding 61 inkjet models. You can now manage Canon printers alongside your lights and robot vacuum in one place. It covers about 90 percent of Canon’s cloud-enabled inkjet lineup.
What I am watching next: whether WeChat’s HarmonyOS version reaches feature parity with iOS and Android by mid-year. The 800-person team is a statement, but users still notice gaps. Group live streaming, certain mini-program APIs, and some payment features are not fully there yet. If Huawei really hits 100 million devices, the pressure only goes up.
