Due to the ban imposed by the US government on Huawei, the company is not allowed to certify any new devices. The company is trying to re-badge its current smartphones and add some incremental changes to the hardware which seems to be the case with the newly announced P30 Lite New Edition.
Everything including the design, camera configuration, SoC, battery and design in the P30 Lite New Edition is exactly the same as the P30 Lite. The changes made in the new smartphone include the fact that the New Edition can now go up to 6GB of RAM and 256GB of internal storage as opposed to the maximum 8GB/128GB configuration on the older model.
This way Huawei can re-release all of its 2019 phones without having to obtain new licenses for the Google Services. Hopefully the trouble with the ban story will end soon.
