Huawei has recently introduced its first tri-fold mobile phone, Mate XT Ultimate Design. The phone is available in two colors: Ruihong and Xuanhei, and is pre-installed with HarmonyOS 4.2 system. Huawei’s Mate XT 3-foldable phone does not support the multi-device task flow function of the HarmonyOS system, and cannot drag applications to “transfer” to other devices for use.
Huawei’s official website shows that some foldable screen phones do not support multi-device task flow in HarmonyOS 3.0 and later versions. The models are as follows:
- HUAWEI Mate X
- HUAWEI Mate Xs
- HUAWEI Mate Xs 2
- HUAWEI Mate X3
- HUAWEI Mate X5
- HUAWEI Mate XT
