    • Once inside look at the area indicated within the pictures and you can see the retaining plugs, one for volume and one for power.

    • (It looks like the retaining plug may slide to release the switch but that was not the case with mine.)

    • Instead with sharp tweezers you can gently pry it out.

    • Once the retaining plug is removed you can free the volume or power switch.

    • The first picture is the plug, look closely how it locks the switch in. The second picture is how it retains the switch.

    • Check for debris within the switch space. Temporarily relocate the switch and check that it functions correctly, you should see the pins contacting the volume/power ribbon switches. If not you may have another issue.

    • Refit the switch by depressing it on the retaining side and and push the retaining plug back in (making sure it is orientated correctly)

    • Make sure the plug is now located properly within the midframe and that the switch functions correctly.

  4. Huawei Mate 20 Pro Power or Volume button Replacement, Why the switch fails: adım 4, 1 resimden 1.
    • The reason why the switch will have stopped working is clear in the picture

    • The switch has lost the lumps which contact the pin in turn pushing the ribbon switches

    • Without these nothing happens.

    • Hopefully this guide has helped as I could not find any information on the internet. I ended up buying a 2nd hand midframe to experiment with.

    • As a result I must be in a small minority of chrome mate 20 pro's with a purple volume button :-) !

To reassemble your device you can just reuse the adhesive and stick on the back glass, some heat will make it adhere better. (check your lenses and lens glass inside and out are clean before reassembly! ask me how I know..)

NOTE: It will obviously now have no guarantee of water resistance, if you want a better guarantee you should remove all adhesive from the midframe and back glass.

Then install a new glass adhesive to the frame and replace the back. (even with this I would still be very cautious with matching the original IP rating)

Vielen Dank für die tolle Anleitung. Mich hatte der Reparaturversuch ca. 3 Stunden Arbeit gekostet, da ich große Probleme hatte den Stopfen zu entfernen. Mein Problem konnte dadurch leider nicht gelöst werden. Es scheint so als hätte der Sturz ein wenig mehr angerichtet als nur den Knopf zu verformen. Der Lauter-Knopf funktioniert, der leiser Knopf leider nach wie vor nicht. Dennoch vielen vielen Dank für die tolle Anleitung, da zu dem Thema leider gar nicht so viel zu finden war.

Thank you, if the volume down is not working but making contact it could be the ribbon switch the the volume presses. Rory

Rory Clements -

Hey Rory, thanks for your Feedback. Do you also have the possibility to write a guide for that? Which parts do I need to remove for that kind of repair?

Jan Winter -

Hi Jan, I would love to write a guide but I do not have the phone anymore. Access to the volume and power ribbon is resonably easy, any full disassembly guide will give you the information you need.
