Poor Bluetooth and WiFi connection after screen replacement

Hello!

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 have the exact same issue with a Y9 2019: screen replaced, everything reconnected properly, but now WiFi, BT, and GPS disconnect constantly. It is as if the range of the antennas has drastically diminished. If anybody can help, it would be greatly appreciated.

Some parts might have been slightly moved during the screen instalation proccess.

In particular, your antenas might not be tightly connected as they should.

Did you guys had any luck, I have the same issue with my Nova 5T poor Blueetoth connection after screen replacement.

Edit: I got the phone like that, but I suspect screen and back glass were replaced due marks around the chasis, I opened the phone myself to see if I could find the problema but everything seem fine, antena was attached properly, got the main board out and back again in its place, its hard to find info online so I dont really know wich is the bt antena and where the bt module is located
