2. The rear cover is made of aluminum alloy, which can be dented by hard impacts. It is
recommended that you use a protective phone case.
Note: If the user asks for a replacement, please inform them that this issue is not covered by
warranty.
2.1.14 What do I do if the phone's rear camera is cracked or
scratched?
Ask the user if the rear camera was damaged at the time of purchase or if it became damaged
after use. If the latter is the case, any breakages, cracks or scratches the user finds on the rear
camera lens after leaving the place of purchase are considered to be caused by the user and
will not be covered by warranty. The user should take the phone to an authorized Huawei
service center for repair.
It is recommended that a protective cover is used for the phone. The user must keep the phone
away from sharp objects (such as keys and sand etc), and avoid pressing the phone hard.
The phone's rear camera lens is made of Corning tempered glass. After surface treatment, it
has a Moh hardness of ≥ 7, and a pencil hardness of 1 kgf > 9 H. All our lenses have gone
undergone strict inspections to ensure durability and resist scratches from daily usage.
However, sharp and hard can objects could still break or crack the lens.
Note: If the user asks for a replacement, please inform them that this issue is not covered by
warranty.
2.1.15 Why is there a big gap between the battery cover and the
structure of the phone, and between the screen and the front
cover?
Due to thermal expansion and contraction and production stability, it is impossible to achieve
a zero gap or absolute evenness.
The industry standard gap is smaller than or equal to 0.3 mm and Huawei's standard is smaller
than or equal to 0.2 mm.
To save going to a service center, please first try inserting two pieces of A4 paper into the gap.
If you cannot insert two pieces of A4 paper, then the gap is smaller than 0.2 mm, because the
thickness of a standard sheet of A4 paper is 0.1 mm. Therefore, the gap complies with the
Huawei standard (0.2 mm) and you can rest assured. If two sheets of A4 paper can be inserted
into the gap, take your phone to an authorized Huawei service center and check whether there
is a quality problem.
2.1.16 Why is there a step difference between the antenna slot on
the side of the battery cover?
Before being colored, the surface of the battery cover is polished and electrolyzed. As a result
of the electrolyzation, the cover metal part will be lower than the plastic part, hence the step
difference.
Huawei has strict quality control regarding such step differences to ensure they comply with
Huawei's standards of less than 0.05 mm. Please rest assured.
This is a normal phenomenon, which is not covered by warranty.
