Huawei hat laut XDA und einigen Berichten der User angefangen in China bei Huawei/Honor die alternativen Lauchner wie zBsp, Nova zu sperren.
Huawei is no stranger controversy with EMUI, the company’s in-house variant of Android. Just recently, they were accused of blocking third-party launchers in the latest EMUI 9 China version, with no concrete information as to why. According to members on our forums, the reason for this restriction is to allegedly combat the shady practices of some third-party retailers in China (a problem we’ve seen Xiaomi deal with on multiple occasions). Now the company has confirmed that it’s done on purpose, but legitimate developers of accessibility launchers can apply to have their applications whitelisted. This does not affect anyone running the global versions of EMUI 9.
