WiFi and Bluetooth barely works - why?

9-year-old’s iPhone 13 mini. Had a very unprofessional screen + battery replacement. Now:

  • WiFi disconnects constantly (especially when gaming)
  • Bluetooth range/connection is terrible
  • Screen flickers on home screen

Already tried the usual WiFi resets, forgetting networks, etc. – no change.

Questions:

  1. On the 13 mini, are WiFi and Bluetooth handled by the same chip or antenna flex cable?
  2. Could a botched screen replacement (tons of leftover glue, possibly damaged flexes) cause both WiFi and BT issues?
  3. Any specific things to check inside?

Thanks so much!

Hi @come8cmice30789

Try using the WiFi in the phone as close as possible to your home network router i.e. <15cm and check if it detects, connects and maintains a stable connection.

If it does, mostly likely it is a problem with the antenna - loose connection or faulty.

Here's a previous answer in ifixit that details how to remove/replace the antenna in the phone.

Answer too:

1 I believe so

2 Most likely not, but I suppose it could

3 I would check the antenna connections, and the connections between the board/screen so you can make sure there are no shorts/kinks in the cables.

Try making sure you have nothing close that can cause interference... Hopefully this works
