Huawei P20 Pro: Perché il volume dei messaggi vocali è basso?

Mon, 27 Oct 2025 06:45:16 -0700

Perché il volume dei messaggi vocali di WhatsApp è basso nonostante sia al massimo?

Da un po di tempo i messaggi vocali che invio con WhatsApp nonostante il volume sia al massimo quando vengono ascoltati sono a volume bassissimo.

Huawei p20 pro: Scocca e schermo compatible

Sat, 23 Jul 2022 06:21:25 -0700

Salve a tutti! Ho danneggiato lo schermo e l'ho fatto riparare con una scocca e schermo compatibile, però il GPS e il bluetooth non funzionano più come prima:

Il GPS non tiene la posizione, quando viene calibrato su Google Maps perde subito la precisione e in modalità navigazione il cursore non si aggiorna insieme al movimento della vettura, rimane in attesa di segnale GPS;

Il bluetooth funziona però a volte salta oppure il range è ridotto. Ad esempio con delle cuffie bluetooth, mentre prima potevo allontanarmi ad una certa distanza dentro casa, adesso la distanza è pressoché dimezzata.

Il riparatore segnala che la scocca è in un materiale plastico mentre quella originale è in alluminio, ed essendo questa a contatto con il comparto antenne (GPS, bluetooth, antenna) è probabile che la qualità del segnale sia ridotta.

Siete a conoscenza di altri casi simili?

A quanto pare l'unica soluzione efficace consiste nell'applicare il ricambio originale, peccato costi circa 190€ mentre il compatibile meno di un terzo, circa 60€

Huawei P20 Pro: No service after screen replacement

Fri, 14 Jul 2023 14:12:09 -0700

Got given a P20 Pro to replace the LCD as it was not working, and was completely smashed on the back.

Replaced the screen, all starts fine, WiFi works but says no service.

Antenna is secured to the frame properly.

Coax cables are snapped in firmly and are not mixed up.

Tried resetting network settings

Cleared Cache

Performed factory reset.

Any other ideas?

Thanks

Huawei P20 Pro: Reboots about every 3 days for no apparent reason

Thu, 19 Sep 2024 11:18:10 -0700

First: this is not a hardware problem, the same thing happens to me on two different phones. Factory reset, obviously, does not help (tried that, of course). Not a Android 8.1 problem either, since I had that on my P6 for a long time, with no random reboots.

Event logger app gives no indication of what the problem is. Phone is not in direct use when it happens. It's not the Fitbit app, which I know can be a problem. Not France24 news app either, even though that doesn't work as it should (1 in 40 notifications come trough, roughly, just like with Skype, but it's more normal with Skype to act like that).

Any other apps that might be the culprit? The Messages (SMS/MMS) app is taking more out of the battery than it should for the lack of usage, but I can't remove it. Same with Phone app.

Huawei P20 Pro: Data recover from a phone with black screen(broken screen)

Huawei P20 Pro: The screen is black, but the phone works (even the touchscreen).

Wed, 22 May 2024 08:06:24 -0700

My P20 Pro turns on, sounds, receives calls, and even the touchscreen works (I can get to the dial and it makes sound when I touch); but the screen is pitch black.

What I tried:

Restarting it to see if it’s a software issue. It restarts, but the screen is still black. I even tried to go to recovery or bootloader and the screen still is black.
Opened it up to see the screen connector. It wasn’t loose, nor dirty or corroded. I cleaned it up regardless, but still it doesn’t work.

So, I want to know if someone has experienced something like this… I don’t know if it could be a screen problem (since it’s in mint condition and the touch works), or it could be something related to the motherboard.

Any ideas? Thank you in advance!

Edit 07/10/2020:

I checked out the screen for a backlight issue, and I didn’t saw any images, but I noticed this blueish line underneath the phone, followed by a faint dark thick line. It covers the whole bottom of the screen. Could that be signs of damage of some sort?

It also goes up a bit from the side.

Edit 23/10/2020:

A CHANGE OF SCREEN FIXED THE ISSUE.

Before the change I fully opened it up, and it showed that water entered from the bottom right speaker. The mic board was fully corroded, and that blueish line that I saw inside the screen was indeed corrosion.

Thank you for guiding me in the right direction!

Huawei P20 Pro: Microphone appears muffled and quiet

Wed, 03 Nov 2021 16:56:40 -0700

Hello all.

My P20 Pro has a problem since being repaired. My microphones appear to be muffled, and do not pick up sound well. They seem quiet but also extra sensitive to physical contact with the phone itself. Would this potentially be the result of dust build up? And is there a simple way to hopefully remove any blockages? Cheers.

Huawei P20 Pro: Screen not working correctly after battery replacement

Tue, 19 Oct 2021 14:13:09 -0700

I’ve just changed the battery of my P20 pro and at first everything seemed to be working fine. Now I’ve realized that the touchscreen is not working correctly anymore. It either registers no input or multiple inputs or inputs way from the initial touch.

Any ideas what may have caused this? Isopropyl maybe (it was only 70%)?

Hey guys,

I cant seem to find info regarding the location of the microphone that is used for video recordings, loudspeaker etc. This is not the bottom microphone near the charging port, that one is used for phone calls. Does anyone know where the second microphone is located? TIA

Huawei P20 Pro: Unresponsive screen after 10 second cleaning in sink (IP67)

Sat, 25 Oct 2025 09:07:13 -0700

Hi, I usually pour some water on my P20 Pro to clean it if it’s dirty. No soap or bathing. I’m just pouring some water in the sink on the phone. The phone does have a small crack at the bottom right corner. But It’s been fine with water anyways. My issue now is that the screen started spazzing around and clicking everywhere at first. Then it started clicking just in a specific row. (Bottom notification bar placement ~ on Android Pie (9.1). Now it’s not responding to my touches at all.

So first I tried shaking water out of speakers and other holes. But the phone should be IP67 water rated. But now as mentioned earlier the screen does not respond to touches at all. So now I put my phone in a plastic bag of rice ~ 15-20 minutes ago and I am going to wait and see what happens. Anyone got any idéas on what it can be and is it cheap or expensive to fix if needed special fixing, and lastly where can you fix it? Huawei’s own support and repair or just any repair shop?

I am really stressed out about the situation right now because I am getting a new phone tomorrow and my mom is supposed to take over this phone and I really don’t want it to be broken over less water than in a normal-sized glass of water pouring.

The black coax cable pulled it's attachment off of the motherboard during my recent DIY job on my p20 pro. Strangely, it doesn't seem to have made any difference to the function of the phone though. Bluetooth, WiFi, mobile data and phone calls are all functioning as normal, as are both microphones and speakers. I'd ready appreciate any advice/help.
