So for a couple of days now since I downloaded the May Security patch I have been having issues with apps not loading, and my signal bouncing back and forth from 4g lte and 5g. I have so far reset my phone, toggled airplane mode on and off, reset network settings, but I'm still having these issues. Has anyone else had any issues since the patch dropped?
Solved! Go to Solution.
Thanks. I downloaded the app Hidden Settings and turned off 5G, preferring LTE. Within a few minutes I had the same issue, the mobile network dropped completely, before restoring 10 seconds later.
I can definitely understand the frustration and inconvenience cause by lack of signal on your S21+ after an update, and am sorry to hear you are experiencing this. First, try resetting your network settings:
From the home screen, swipe down from the Notification bar then select the Settings icon > scroll to and select General management > Reset > Reset network settings > Reset settings > Reset.
If that does not help, you can do as Yamialex224 suggested and power cycle the phone by shutting it down, waiting approximately 60 seconds, and then turning the device back on.
You can also try Safe Mode, to see if a third-party application is causing this behavior: https://www.samsung.com/us/support/answer/ANS00062983/
If these steps and guides do not help, I would recommend talking to your service provider, in this case Verizon. Your networks and connections over the air are managed and provided by them, so they would be able to best assist.
