When your Sony Xperia 1 VI stops ringing for incoming calls, it can feel like you're suddenly cut off from the world. This is a common Android headache with a few different potential triggers, from a simple toggle you've missed to a deeper network hiccup. The good news is you can usually get it sorted with a few minutes of focused troubleshooting.
Start With These Quick Checks
Before we get into the weeds, run through these simple steps. I'd start here, as one of them often solves the problem right away. First, pull down the notification shade twice to see the full Quick Settings panel and make sure the Airplane Mode icon isn't lit up. Toggling it off and on can sometimes kick the radio back into gear.
Next, give your phone a fresh start. Press and hold the Power button and Volume Up button together for about ten seconds, until you feel the phone vibrate and the Sony logo appears. This force restart clears out any temporary glitches that might be blocking calls.
Finally, take a quick glance at your signal indicator. If you're seeing only one bar or an "X," the issue is likely poor network coverage and not your phone itself. Try moving to a different location or near a window.
Review Your Do Not Disturb and Focus Settings
It's easy to accidentally enable a mode that silences everything. On your Xperia 1 VI, swipe down and check for a "Do Not Disturb" or "Focus" icon in the quick settings. If it's active, tap it to turn it off.
For a more detailed look, go into Settings > Sound & vibration > Do Not Disturb. Make sure the main toggle is off and review any schedules that might be active. Also, check the "Allowed" section to ensure "Calls" or specific contacts aren't being blocked.
Inspect Call Blocking and Spam Protection
Sony's software includes spam protection that can sometimes be a bit overzealous. Open your standard Phone app and tap the three-dot menu in the top right, then select Settings > Call blocking & spam.
Look through the "Blocked numbers" list to make sure a important contact hasn't been added by mistake. You can also temporarily disable "Spam protection" or "Caller ID & spam protection" to see if that's what's silently rejecting incoming calls.
Check for Active Call Forwarding
If your calls are being silently sent to another number, you won't get any notification on your Xperia. To check this, open the Phone app, tap the menu, and go to Settings > Calling accounts > [Your Carrier] > Call forwarding.
Ensure all the options like "Always forward" or "When busy" are set to your number or "Turn off." Sometimes these settings can get changed accidentally, especially if you've been fiddling with carrier codes.
Examine Your SIM Card
A loose or faulty SIM card is a classic culprit. The Xperia 1 VI uses a combo SIM tray on the side. Grab the included SIM eject tool or a small paperclip, pop out the tray, and carefully remove the SIM card.
Give the gold contacts a gentle wipe with a soft, dry cloth and then reseat the card firmly in the tray. Push the tray back in until it clicks. Once the phone reboots, see if your signal returns and you can receive a test call.
Reset Your Network Settings
This is a more thorough step that clears all your network-related configurations. It will forget Wi-Fi passwords and unpair Bluetooth devices, but it can resolve persistent calling issues. Go to Settings > System > Reset options.
Tap on Reset Wi-Fi, mobile & Bluetooth and confirm. Your phone will reboot. Afterward, you'll need to reconnect to your Wi-Fi and repair any Bluetooth accessories, but it often cleans up obscure network bugs.
Update Your Software and Apps
Running outdated software can lead to compatibility problems with your carrier's network. Sony's update schedule can be less frequent than some brands, so it's worth manually checking. Head to Settings > System > System update to see if a newer version of Android is available.
Also, open the Google Play Store, tap your profile icon, and go to Manage apps & device > Updates available. Make sure your Phone app and Carrier Services app are updated, as these are critical for call functionality.
Clear the Phone App's Cache and Data
If the app itself has corrupted temporary files, it can malfunction. Go to Settings > Apps > See all apps. Find and tap on "Phone" (it might be called "Google Phone" or similar). Select Storage & cache.
Tap "Clear cache" first and test. If the problem persists, you can try "Clear storage" or "Clear data." Be aware this will reset the Phone app to its default settings, erasing your call history and any custom settings within the app.
