So as you guys know, vienna is my hometown, and im really proud that the first huawei service store openend its gates here. A few months ago I was also here to checkout the gluegate on the mate 20 pro and Huawei has learned alot from this, and took care and precautions about this issue on the p30 pro. Today we will open up a fresh p30 pro with Mr. Kumar, who has more than 20 years of experience in the mobilephone repair business, and we will also have a closer look at huaweis quad leica camera.
When you enter the repairing facility you have to do an ESD check and put on some special shoecovers. Also Mr. Kumar has to wear an ESD wristband and do daily ESD checks, so no hardware gets damaged due to ESD during the repairs. First like on every waterproof smartphone that has an IP rating, we need to heat it up to weaken the glue. In order to do this, we put the p30 pro on a heating plate and heat it up to 80° celsius for a couple of minutes. Then Mr. Kumar takes the phone and starts to remove the backcover with the help of a suction cup and a tool which is a little bit thinner than a credit card. Its not really easy and you need to be careful as you can easily break the backcover if you apply to much force. There is a video on youtube where the guy removes the back with a metal tool, but I wouldnt recommend it as you can easily crack the backcover. Once the backcover is removed, you already see the massive coil for wireless charging, the motherboard at the top with the cameras and the big 4200mAh battery.
There is plenty of glue left inside of the frame of the Huawei P30 Pro which Mr.Kumar has to remove before he can proceed. Now there are plenty of screws which have to be removed in order to remove the cameras and the motherboard, also there are some stickers on the screws which are basically warranty seals. The connectors of the camera are really tiny and the flex cables can be damaged easily. Mr. Kumar is using a tweezer to carefully remove them and get the modules out. The biggest one is actually the zoom camera as it is using a periscope and redirects the light by 90° to the sensor and has got a bunch of lenses inside of the periscope. The next biggest one is the main camera in the middle with its big 40 Megapixel sensor and at the top we have the wideangle camera.
The TOF camera, or also called time of flight camera which is used for bokeh shots and depth inforamtion is the smallest module. After that we had a look at the battery aswell and got confirmed that it has 4200mAh typical and 4100mAh rated capacity. The rated capacity of the battery is simply the energy capacity of the battery under normal condition and the theoretical one would be the 4200mAh, so thats no cheat, thats what every battery manufacturer is putting on their batteries and you probably have seen it already on powerbanks. So far it looks very well built and easy to repair, but the repairing times stated by huawei are really tough and the workers have to be really skilled in order to replace things like the display quickly. Also the waterproof body doesnt make it easier. When Mr.Kumar reassembles the phone he has to be really careful and doublecheck that all the old glue has been removed, otherwise the new backcover may not sit perfectly and then the phone wouldnt be waterproof.
So he is removing the foil from the glue and presses the backcover on the phone then he double checks it and has to heat it up again to 80° to soften the glue. After this, he puts the phone in a special tool designed for the huawei p30 pro. Then he puts the tool into a mechanical press which makes sure that there is enough force on the backcover and that the backcover is fully pressed into the frame. This also ensures that the phone is waterpoof again after the whole process.
After every repair he has to check the phone with huaweis own diagnostic tool. its basically a computer program that pushes and diagnostic APK to the smartphone over USB debugging and then runs several tasks which are testing the phones hardware like the camera, microphones, touchscreen, display and more. After the test is done and finished to 100% the phone is ready to go out to the customer again. All that is done within usually 30minutes depending on the issue and they repair up to a thousand phones a month in this location.
All in all, without being biased, I think its really cool that huawei has opened this service store to engage customers, but I do think there is a long way to go to fully roll this out
worldwide and offer a customer service that fits the premium brand they want to be. So thanks to Mr. Kumar for his awesome performance and skills and thanks to Huawei to let me have a look behind the scenes.
