Huawei P20 (EML-L29) runs Android with Huawei Mobile Services and it's supported by PhoneCopy.
Huawei is gradually launching mobile phones that include the Android operating system without Google services, also known as AOSP or Android Open Source Project. Similarly like on the other smartphones you can download applications from the application store named AppGallery directly to your phone. When you buy a new phone you need to transfer your personal data from the old phone before you start to use it. This is a reason why PhoneCopy should be the very first application on your phone. Later you can use it to back up your contacts, SMSes, photos, and videos to keep it safe in the case when your phone is lost or damaged.
With PhoneCopy you can easily transfer your contacts, SMSes, photos, and videos to any other phone and it doesn't matter if it is a smartphone or feature phone. It takes a few seconds and you can call your business partners or friends again.
