Huawei started testing a third beta version of HarmonyOS earlier this month and it has another one on the way. This upcoming version will arrive on March 31 and it will be the final beta.
Today the company announced that a stable release is coming in April and that the foldable Mate X2 will be the first phone to receive it as an update. The phone launched with Android 10, but it will soon jump ship. And many other devices are expected to follow it.
The Huawei P50 phones were supposed to be the first to run Harmony out of the box. Though it was never officially confirmed, the new flagships were originally scheduled for a March reveal, presumably going on sale a bit later (enough to give the OS team time to put the finishing touches).
However, the latest information on the P50 series is that the announcement has been pushed back to May. By the time the P50s arrive, HarmonyOS will have been around for a month or two.
Speaking of the P50 series, @HoilNDI has posted renders of the vanilla Huawei P50 (a couple of days ago the same leakster posted P50 Pro+ renders). The renders show a triple camera (no periscope lenses here, of course), what looks like a 3D ToF sensor and a flash, all spread out across the characteristic camera bump.
