P8 Smartphone FAQs
6.6 After two phones are connected and set, why can't my
phone display a tab of USB options?
The OTG cable and the USB cable may be reversely connected. The OTG cable should be
connected to auxiliary test phone B and the USB cable should be connected to primary test
phone A.
6.7 Why does the Manage apps show that my phone's
memory is less than 2 GB or 3 GB?
A certain part of your phone's internal storage space is reserved for the cache of the modem,
camera, and GPU, which is not managed on the Android system. Such an arrangement is
beneficial for implementing the phone functions. Your phone's actual RAM is still 2 GB or
3 GB.
6.8 Why is some of my phone's memory still occupied
after I clear all the recently used applications?
After you use your phone for a long period of time, various applications create a lot of
background service processes. The system needs to save these processes, and therefore these
applications are not stopped or terminated when the available memory is sufficient. Compared
with the memory usage upon system startup, there is a memory difference for 100 MB to 200
MB or more.
6.9 Why doesn't my phone display any notification after I
connect it to the computer?
After you connect your phone to a computer using the USB cable, if no notification is
displayed, check whether you have selected the Do not prompt option before. If yes, modify
this setting in the drop-down menu.

Your microSD card may not be produced by a trusted manufacturer (such as Kingston or
SanDisk), which may not be compatible with your phone.
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.
Format the microSD card on your phone (with the help of Huawei technical support
engineers).
