5.11 Why can't my phone detect certain microSD cards?
1. Your microSD card may not be produced by a trusted manufacturer (such as Kingston or
SanDisk), which may not be compatible with your phone.
2. Huawei phones do not support non-standard microSD cards. Compared with the standard
microSD cards, there is a metal plate on the non-standard microSD cards, used to
provide other functions except for the storage function. If you use such a type of
microSD card, you can paste the extra metal plate with gummed paper (the thickness is
about 0.1 mm), and therefore you can use this microSD card normally.
3. Format the microSD card on your phone (with the help of Huawei technical support
engineers).
4. The compatibility of Huawei phones with the microSD cards will be improved in new
versions.
5.12 How do I use my microSD card?
Put your microSD card into the card slot and install it to your phone by following the
onscreen instructions.
In Files, you can copy files to the microSD card. In Camera, you can set to save photos and
videos to the microSD card.
5.13 Why can't I perform USB debugging?
Go to Settings > About phone. Touch the build number for seven times in rapid succession to
enter the developer mode. Then, touch the back key to return to the settings menu. Touch
Developer options and enable the USB debugging mode.
