Sept 15th 2022 Android 12 Patch killed mobile data

[ataylor]

I'd finally gotten Android 12 to the point where it was nearly stable and livable, and then the security patch yesterday completely hosed mobile data. WiFi still works. I've tried most of the tricks - restarting, resetting the network , resetting the entire phone, no joy. Anyone else fighting this? Any suggestions?

Hi, keren_ASUS, I have since changed my device from the Zenfone 8 to a Zenfone 9......and after only a week I wish I hadn't 😭, random reboots, apps not loading data, very poor WiFi signal.

The APN settings you gave seem to work, but I also now have it working using the APN settings on Consumer Cellular's page, which are a bit different than what I used to have. I used the AT&T settings below.

Hi @keren_ASUS,
I was one of the people who had no cellular connection at all since the WW-31.1010.0411.122 update.
I went through the troubleshooting steps while recording a log. As it turned out, setting the APN per Consumer Cellular's instructions worked to restore cellular connectivity. So it seems like the update deleted my APN settings, I guess? Anyway, I uploaded the log:

Thanks for your help!

Setting the APN settings restored my data and calling on Straight Talk (AT&T network). The reason why I hadn't tried that sooner is that you can only add or change APN settings on your primary SIM card, so if you have two SIM cards, make sure you switch the non-working one to primary before editing the APN settings.
Additionally, prior to February 2022, cell companies in the USA offered 3G, which didn't need correct APN settings for voice and simple texting (SMS). So it was easy to tell if APN settings were wrong vs. no service at all. But now everything goes through 4G/5G data, at least in the USA, so now if APN settings are wrong nothing works.
