Google’s latest software update for Pixel devices has introduced a bug that causes mobile data connection issues for some users. Affected users are reporting intermittent data loss and complete signal drops, although the issue is not widespread.
The bug was first spotted by PiunikaWeb and highlighted on Reddit, with users sharing their struggles with mobile data connectivity. A simple fix involves resetting network settings or disabling 4G/VoLTE calling.
To quickly reset your network settings, go to Settings > System > Reset options > Reset Mobile Network Settings. Note that this will erase saved Wi-Fi passwords and Bluetooth connections.
Alternatively, try deactivating 4G/VoLTE calling by going to Settings > Network & Internet > SIMs > Provider’s name and disabling Wi-Fi calling. This has reportedly fixed the issue for at least one Pixel 7 user.
While Google has not officially acknowledged the bug or rolled out a fix yet, these temporary workarounds may help users affected by the issue.
