I downloaded and installed the latest Samsung software update yesterday (Mon May 25) and since then my Galaxy S9+ will not connect to 4G. I have autoconnect selected in settings. Any ideas?
Hey @Marie641 ,
can you try your phone in Safe Mode to see if a third-party app is causing this to happen? To do this press and hold the Power button until you see Power Off, Restart, and Emergency. Press and hold the Power Off icon until it shows a Shield, tap the Shield and the device will restart in Safe Mode.
Is the phone connecting to 4G whilst is running in Safe Mode?
That is OK. Have you tried to turn the phone off, remove the SIM card, give the golden contact a wipe, and put this back on the phone? If so, please run the following check to see if there is anything wrong with the SIM card itself: Head into Samsung> Samsung Members> Get help> Interactive checks> SIM.
Are you on the Samsung Members app? If so, can you send me a screenshot of what you see when you launch the app so I can provide you with the next steps?
To capture a screenshot, press and hold the Power and Volume down buttons at the same time (for approximately 2 seconds). If no option is selected, the image automatically saves in the Gallery.
