I lost bluetooth and wifi connections

Hi @jojoandme ,

Do the WiFi and BT turn on OK?

If so try placing the phone as close as possible to either a WiFi router or a BT device and check if there is an entry in the list of available connections dependent on the signal type being checked.

If there is then it may be that there is an antenna problem in the phone. WiFi and BT use the same frequency (2.4GHz) so they share the same antennas.

Here’s the ifixit 三星 Galaxy A50 屏幕更换 guide. I realize that the screen is not the problem but the guide is useful as it shows how to open the phone and access the antennas to see if they’re both connected OK.

Here’s an image taken from Step.14 of the guide that shows just one end of the antennas and where they are connected. Unfortunately there are no images showing the other end of the antennas but you should be able to see them and check once the phone is open.
