Z410 plus has problematic sdcard handling - sdcards are in unwanted order

The problem is: Without an external sd card inserted sdcard0 is the internal emmc memory. But once I insert an external sd card this card itself becomes sdcard0 and the internal virtual emmc sdcard changes to sdcard1. This leads to inconsistent file paths. I can't remove or insert my external sd card witout destroying file links for applications saving files at the sdcard0 path. Also the sd card access is much slower. So also from a performance point of view this behavior is not desirable. I bought the phone because it has one of the smallest displays currently available at the same time with 16 GB internal memory. The behavior of the sd card memory came up totally unexpected. If this can't be solved I'll have to return the phone.

 

The relevant lines in the fstab look like this:


/devices/mtk-msdc.0/11230000.MSDC0   auto      vfat      defaults voldmanaged=sdcard0:emmc@intsd,noemulatedsd
/devices/mtk-msdc.0/11240000.MSDC1  auto      vfat      defaults     voldmanaged=sdcard1:auto

 

I figured out so far that MSDC0 seems to refer to the internal virtual sd card and MSDC1 to the external sd card. So it seems to me that the fstab entries should normally lead to persistent sdcard mounts always mounting the external sdcard to sdcard1. Is it possible that this a bug in Kitkat 4.4.4 or is it possibly a mistake by acer?

 

Thanks,
