I have a P30 Lite 10 days ago I dropped my phone and the screen was broken, almost nothing could be seen and touchscreen didn’t work that well.
Someone replaced my broke screen, and after the replacement wifi and bluetooth have weak connection. It does not connect at my living room and bedroom, where it connected before the repair.
I tried factory reset, restarting the wifi router and nothing works.

Hi @jose12 ,
Try using the phone’s WiFi as close as possible to the router to see if it works OK.
If so then there is an antenna problem. The WiFi and the BT use the same antenna as they both work on the 2.4GHz band.
The phone will have to be opened and checked that the antenna has been reconnected properly.
Here’s an image taken from a teardown video of the phone that shows the antenna cable and connection in the phone.

If you paid for the screen repair take it back to the repairer and tell them about the problem, as they didn’t test the phone properly after it was fixed.

Actually, being 2 feet from the router is fine, problem is when I go to the room next to it, is starts to lose signal range. Tomorrow I'll take it. Thank you very much!
Have you found any solution? I got the same issue with a P30 Pro.
I suppose that it's a common problem wit Huawei because I just placed a new display on a P30 and I have the same problem, checked the connections and all is well connected, some one any idea? I could think of something in the frame that may have something to do with the wifi antenna ?
I have the same problem. Has anyone found a solution?
I've repaired a Huawei P30 and after replacing the new display with frame I got same problem, bad wifi and BT and I checked the whole old frame but couldn't find anything different as the new but I know almost for sure that it has to do with the frame, I aked the seller about the new frame but no issue about the frame he said, I gave the complete P30 to him to check it and sometimes something faulty happen when opening the phone, you have to be very carefull when you take the uper black part of the phone because very near the left upperside there are some very small parts on the PCB that came easily of when you put a tool to take that part of. Finally I bought a new display without frame, put it on the old frame and everything works. There's also an issue about the fingerprint when you place a new display, fingerprint won't work after placing a new not original Huawei display, Samsung has same problem. Greetz
Deseo saber si tuvieran solución a este problema ya que tengo la misma situación con un p30 leica, quién hizo el cambio de la pantalla no sabe porqué situación no agarra el wi-fi ni el bluetooth, lo lleve a otro y también no saben ellos dicen que supuestamente la pantalla o el marco de la pantalla es la antena para wi-fi y Bluetooth, y tengo el mismo problema qué a corta distancia del router enlace ipasa 23 minutos y se desenlaza solo o el bluetooth antes lo usaba con mis audífonos bluetooth y ahora ya no me deja, si alguien ya soluciono este problema pasen el dato por favor

A quién ya le dieron resolución pasen el dato no ser malos por favor
A mí me arreglaron el CEL haciendo un reballing de la antena de wifi/Bluetooth. Ya con eso quedó
A mí ya me solucionaron el problema, tuvieron que hacer reballing a chip de la antena del wifi y Bluetooth (vienen juntas en un solo chip). Ya con eso se solucionó.

okay, pero no te comento la persona que realizo el reballing si habia peligro de hacerlo o que ya podia suceder que no prendiera, antes de hacerselo, ya que a mi as de cuenta que nadie lo quiere hacer y comentan que puede dañarse ni prender el celular p30 leica
¿Que es un reballing?
