One UI 9 is breaking Wi-Fi, mobile data, and even SIM detection for some Galaxy users - Android Authority
Android Authority is reporting on the story above. It caught our attention because it may affect readers checking their internet or a specific service on SpeedTestTools right now.
When your phone suddenly drops offline, it is natural to blame your home broadband or your cellular provider. However, operating system updates can sometimes disrupt the very tools your device needs to get online. If your smartphone stops connecting to local wireless networks, cuts off your mobile data, or fails to recognize your physical or digital SIM card, you are left completely stranded through no fault of your internet provider.
If you have not installed this latest software yet, your best move today is to pause automatic system updates until a fix arrives. If you already updated and suddenly cannot browse the web, check your connection settings to see whether your phone detects your SIM card or allows Wi-Fi to toggle on. Recognizing that the software is at fault will save you from wasting time resetting your home router or waiting on hold with your carrier.
If your device is working fine right now, hold off on system updates until a patched release becomes available.
