When your Sony Xperia 1 VI won't send pictures, it's usually a quick fix. The most common culprit is a simple setting or a temporary network glitch. I'd start by checking your mobile data and the specific messaging app you're using.
Check Your Mobile Data for MMS
If you're trying to send a picture via text (MMS), you need mobile data turned on, even if you're connected to Wi-Fi. Head into Settings > Network & internet > Mobile network. Make sure "Mobile data" is enabled.
Also, check your Access Point Name (APN) settings here. An incorrect APN can block MMS. Your carrier can provide the correct settings if they look wrong.
Verify the Messaging App's Permissions
Your messaging app needs permission to access your photos, media, and files. Go to Settings > Apps > See all apps. Find your messaging app (like Google Messages) and tap Permissions.
Ensure "Photos and videos" or "Files and media" is set to "Allow." Without this, the app can't attach the picture you're trying to send.
Toggle Airplane Mode
A quick network refresh can clear up signal hiccups. Swipe down from the top of your screen to open the Quick Settings panel and tap the Airplane Mode icon. Wait about 10 seconds, then tap it again to turn it off.
This forces your phone to reconnect to your cellular network and Wi-Fi from scratch. Try sending the picture again once the connection is re-established.
Force Restart Your Xperia
A soft reset can clear temporary software bugs causing the hang-up. Press and hold the Power button and the Volume Up button together for about 10 seconds. You'll feel the phone vibrate and see the Sony logo as it restarts.
This is different from a normal power off and on. It's a clean reboot for the system. After it boots up, open your messages and give it another shot.
Clear the Messaging App's Cache
Corrupted temporary data in the app can cause sending failures. Go to Settings > Apps > See all apps. Select your messaging app and tap Storage & cache.
Tap "Clear cache." This won't delete your messages. If the problem persists, you can try "Clear storage," but be aware this will reset the app and erase your conversation history within it.
Check Your Date and Time Settings
An incorrect system time can sometimes interfere with network authentication. Open Settings > System > Date & time. Make sure "Use network-provided time" is switched on.
If it's already on, try turning it off and setting the date and time manually, then switch the automatic setting back on. This can resync things properly.
Try a Different Messaging App
This is a great way to figure out if the problem is with the app itself or with your phone's system. Download a different app like Signal or WhatsApp from the Google Play Store.
Try sending a picture through the new app. If it works, the issue is likely with your default messaging app. You can stick with the new app or reinstall your old one.
Disable Data Saver or Battery Optimization
Power-saving features can restrict background data, which MMS needs. Go to Settings > Network & internet > Data Saver and make sure it's turned off.
Also, check Battery Optimization for your messaging app. Go to Settings > Apps > See all apps, select the app, tap Battery, and set it to "Unrestricted."
Update Your Software and Carrier Services
Outdated software can have bugs that affect messaging. Connect to Wi-Fi and go to Settings > System > System update to check for an Android update.
Also, open the Google Play Store, tap your profile icon, and go to Manage apps & device > Updates available. Look for an update to "Carrier Services" or your messaging app and install it.
Reset Your Network Settings
If you're still stuck, this will reset all network-related settings to default. Go to Settings > System > Reset options. Tap "Reset Wi-Fi, mobile & Bluetooth."
Confirm the reset. Your phone will restart. You'll need to reconnect to Wi-Fi networks and re-pair Bluetooth devices afterward, but it often resolves persistent MMS and data issues.
