Communist cute kitten, I do not advise you get a Huawei phone with HarmonyOS unless you are actually fluent in Chinese, based in China, and not interested in apps outside China. Given your name, 可爱小猫, you might be fluent. But given your use of Lemmy, I doubt you are a mainland local.

HarmonyOS latest update is a fully localized OS that uses a localized app store and can only run a few non-Chinese apps in a virtual machine, with restricted memory access. If that appeals to you, go for it.

Edit: Huawei is a special case. It has been heavily sanctioned and has cut ties to the Android ecosystem. Oppo / Oneplus phones are available in China variant, and they run Android. They are pretty much the same as a local phone, as long as your cell provider doesn’t IMEI blacklist you. Mine runs on Canadian wireless providers when I’m in Canada.

Good strategic analysis.

If you buy a mainland China phone the app store will be local, for example Oppo store, and Play will be only available as a workaround. I think mainland China phones will be unaffected by Google’s sideloading restriction.
