Hi Belén,

the tape is more of a protective film and doesn’t have a function which would affect the phone when not reapplied.

Hi Christo,

the display cable of the Huawei P20 Pro is held in place by adhesive underneath the battery. Not removing the battery and loosening the adhesive underneath the cable will result in damage to the display and/or display cable when trying to lift the screen. At the same time the glued cable will hold the display in place and it won’t be possible to lift the display high enough to open the ZIF connector of the fingerprint without causing critical tension to the cable. However it can be possible to do it the way you were mentioning but this will require some experience with smartphone repairs and a good amount of instinctive feeling.

Hi Tim,

for the left and right edge you should use 1 mm, for top and bottom it can be a bit wider. Or can use the Precut Adhesive Card.

Hi axl1972,

is this the guide you are looking for?

Hi Michele,

yes, the use of isopropyl alcohol is a common technique when removing a battery in a smartphone. Especially when the adhesive is very strong. Try to apply the alcohol to every corner of the battery and let it penetrate the adhesive for several minutes. Start the prying procedure with the spudger afterwards. In case the adhesive isn’t loose enough you can reapply isopropyl alcohol any time during the removal. Keep in mind, that there’s a gap in the midframe for the display flex cable. It can happen that the isopropyl alcohol runs trough that gap and loosens the adhesive of the display as well. When the display adhesive gets loose you’ll need replacement adhesive for the display. To avoid that, apply as less alcohol as possible at a time and take especially care during prying to avoid damage to the flex cables underneath the battery. The adhesive of the cables will get loose as well.

Hi Ale,

when replacing the battery you won’t lose any data as long as you don’t damage any relevant components for data saving.

Dato che purtroppo non parlo italiano, ho creato questa risposta con l'aiuto di un traduttore. — Quando si sostituisce la batteria non si perderanno dati finché non si danneggiano componenti rilevanti per il salvataggio dei dati.

Hi Marcel,

the Antenna connector is a COAX connector. You can find a little more information here.

Hi Jeremy,

because of the build of the phone it is nearly impossible to break the microphone or it’s gasket that way and your phone should be fine. In case you’re more interested into the build of the phone, I answered a similar question regarding puncturing a microphone hole in the frame here: I inserted the pin in the left bottom microphone. The question was for the Huawei Mate 20 Pro but the mic build is more or less the same just in another location.

Hey Ryan,

thanks for mentioning. That’s right and I added a bullet for this action.

Try to make sure to remove the SIM card tray and the screws at the bottom end of the phone before you try to lift the display, both block the display whilst removing the back cover. For the case that you’re using two suction cups instead of an iSclack, try to place them as close to the bottom edge as possible. For the case that the suction cups fall off easily, you can put a little water on them before pressing them on the phone. As you mentioned you can try using a blade/opening pick/jimmy as a lever during the removal procedure or you can use a tool like a spudger and insert it into the USB port to press the assembly out of the rear cover but take care to avoid damage to the port. The plastic clamps can sit really tight sometimes. In case the frame is damaged or bent you’ll need more force to open the phone.
