Lucky you, I have on of the P10 with DDR3 and how knows if it has also eMMC5.1 instead of UFS2.1, and the problem is that I bought it more than a month ago here in Spain. I guess I will have to argue with the shop in order to have it replaced by a new P10 that MAYBE it has the same problem.
Man, I switched from Xiaomi in order to avoid several things (besides ROMs) like the quality of the manufacturing process (sudden death and things I've suffered in the last couple of years with several Xiaomi models) and now Huawei is even worse. I am very disappointed with Huawei, this is my first and maybe last Huawei phone.
At the end all manufacturers have their problems, Samsung with the Note model is an example. Maybe paying more than 800€ for an iPhone is worthless at the end...
