Hello I have a xz2 compact (H8324) for 2 weeks. I have a fast sd card (Sandisk Extreme v30 U3 A1 64 GB) but only get data transfer rates of 18MB / s reading and writing. where is the problem ? same card had over 30 MB / s in my old china phone and should make over 100 MB / s? What can I do to speed up the transfer? The Software of the phone are the latest Version 51.1.A.11.26.
Greetings from Germany
