I’ve recently replaced the screen of my Huawei P30 Pro Dual-SIM (VOG-L29). Since that, I have a little less WiFi signal, but most importantly, my Bluetooth signal is very bad and every little move of my phone or the headphones makes it stutter and lose the connection. Both antenna flex-cables are attached. When I hold my hand close to the camera, the connection breaks instantly. No software changes did help. What parts could fix this problem? Is maybe one of the antenna cables faulty? Thank you very much for any advice on this.

I am writing to inform you about a recent issue I have been experiencing with my phone. Lately, my phone has been automatically connecting to a VPN when connected to Wi-Fi. This problem causes many important applications to stop working, and it does not occur when my phone is connected to mobile data.

Thank you for your support.

Best regards

Salve a tutti, ho un Huawei P30 Pro finito sotto una macchina. Possibile recupero dati con il metodo chip off? I connettori fpc sono danneggiati, così come il flat di ricarica che va dalla main board. Il telefono ha pure il blocco schermo.

Hi, yes but screen is destroyed and there is screen lock.

fpc flat is broken, I must hold it in one precise position to make smartphone recognize. In truth pc try to recognize it.

The usb c port has been replaced so as the loudspeaker, I have tried multiple headphones, also tried the headphones on another device.

It charges perfectly, connects to my laptop fine, it just will not recognise my headphones.

Audio works fine via loudspeaker and bluetooth.

So I ordered a replacement sim module, opened the back cover of the phone and to my surprise (before doing any repair) the fingerprint sensor came online instantly and the sim registered on the network! I waited two days and all was working fine with no back cover. So I replaced the sim module to be safe. All still good.

I wait a week for some B7000 glue to arrive, in which time the phone was fully functional. I clean off the old glue with isopropyl alcohol, add new glue seal her up and wait 4 hours. I come return to find the original issue (no finger sensor and no sim recognised). Any ideas??? I'm considering just leaving the back cover off and getting a case :-)

Hello. sorry, do you happen to know the values ​​of the elements in the photo?

I'm unsure why it appears to have a fry mark where it obviously burnt out, i will fit a 100 ohms resistor and then test that pin to earth.

Also can you help advise how to remove the shields on this board, particularly the one on the rear side of where the battery connection is. Is it just a pry off or is there any solder to melt?

Any help or advice would be much appreciated
