Now it’s all done.

As the flagship device of Huawei P series, Huawei P9 has all the standard features of flagships, all metal
design and 2.5D glass. The biggest highlight is absolutely the dual-rear camera. With the first try of
dual camera on Huawei Honor 6 Plus, P9 seems more confident on such design.

At the launch, Huawei used almost half of the time to advertize its cooperation with Leica. Is the dual-
rear camera of Huawei P9 just a gimmic or a trend? This is up to the feedbacks of the market. Dual-rear
camera is more much diffcult than single one, technically speaking. And very few manucfacturers can apply it well.

Huawei P9’s internal design is very simple, the connectors between the components are quite simple. The
components are put on the screen frame, the whole teardown is pretty easy, except for the Fingerprint ID
module on the back cover. But this would make trouble for after-sales repair. For high-end devices, its is
more convenient to repair if the screen has an independent frame. Besides, P9’s internal design is not
that good-looking, the colors of its components are a little messy.


Screw types: 2 in total and 12 pieces. 2 Pentalobe screws and 10 Philips screws.

Structure design: There are around 25PCS structure parts, quite easy to assemble and disassemble.

SIM Card tray: There is “T” design at the front of the tray, avoiding the SIM card tray damaging the
interal SIM/TF card.

Ambient light and Distance Sensor design: Ambient light and Distance Sensor are pasted on the small board on the front shell, connecting by the motherboatd contact spring, convenient for assembling and after- sales repair.


SIM Card tray: The 2 in 1 design of SIM card tray cap and card tray is not recommended, it may be convex
or hollow.

Battery: The battery is fastened by easy remove tape and double-sided adhesive tape, not convenient for
after-sales repair.

Internal design: The whole internal design is quite simple, but the colors of the internal components are
not unified.

Conclusion: Now, we can see the Huawei P9 is easy to take apart and repair, takes just 6 steps. This has a
lot to do with its simple internal structure that makes every compoment easy to remove. So, don’t worry,
if you Huawei P9 needs to be repaired.
