Step 1: Since your touch screen is not working, you can factory reset it using Google’s Find My Device web service.

Step 2: Go to Find My Device from any device and sign in to the Google account associated with the damaged screen device.

Calls on Vivo Y78 5G Go Straight to Voicemail? 12 Fixes

Have you ever experienced incoming calls to your phone go straight to voicemail without ringing? It can be frustrating, especially if you’re expecting an important call. It could be due to simple things like turning down the volume or forgetting to turn off the Do Not Disturb mode. In other cases, it might be because you accidentally blocked the caller’s number.

In most cases, incoming calls going to voicemail without ringing are common. However, if it’s happening frequently or for all calls, your phone may have a problem.

This article will discuss why incoming phone calls go straight to voicemail and how to fix the problem. We’ll also show you how to use Wondershare Dr.Fone, a powerful Android System Repair tool, to solve such issues. So, if you’re uncertain why that last call went straight to voicemail, keep reading, and we’ll cover everything you need to know.

Part 1: Not Ringing? Here’s Why Calls on Your Phone Go Straight to Voicemail

If an incoming call to your cell phone goes straight to voicemail without ringing, there could be a few reasons. Here’s what to look for and what you should do to fix it:

1. Turn Off Do Not Disturb (DND) Mode

DND mode is a feature that silences all incoming calls, notifications, and alerts. If DND mode is enabled, your cell phone goes straight to voicemail when someone calls. To turn off DND mode, swipe down from the top of the screen to open the notification settings panel, then tap the Do not disturb icon.

Here’s an alternative way:

• Step 1: Open the Settings app and go to Notifications.
• Step 2: Tap Do not disturb.

• Step 3: Toggle Do Not Disturb offto disable the mode.

2. Turn Off Call Forwarding

One reason calls go straight to voicemail without ringing is if you enabled call forwarding. Call forwarding is a feature that redirects incoming calls to another number. To turn off call forwarding:

• Step 1: Open the Phone Dialer app on your device, then tap the menu icon and select Settings.

• Step 2: Navigate to Supplementary services > Call forwarding.

3. Disable Call Barring

If a phone call went straight to voicemail, another possible explanation is the call barring. It is a feature that restricts calls from being made or received on your phone. If activated, it can cause incoming calls to a phone to go straight to voicemail. To turn off call barring on Vivo Y78 5G devices:

• Step 1: Open the Phone Dialer app, then tap the menu icon in the top right corner.
• Step 2: Go to Settings > Supplementary services > Call barring, then tap OK.
• Step 3: Select Voice call, then turn off your preferred outgoing and incoming calls. When prompted, enter 0000 as a password.

4. Update Your Phone’s Software

Sometimes, software bugs can cause problems with incoming calls, which may be why your last incoming call went straight to voicemail. If your phone runs outdated software, try updating it to the latest version.

To check for updates, open the Settings app and go to Software update or System update. For a seamless update experience, follow the step-by-step instructions on your mobile screen.

5. Reset Network Settings

If the incoming calls on your phone go straight to voicemail, consider resetting your phone’s network settings. Network settings control how your phone connects to the cellular network. If these settings are not set up correctly, incoming calls may not be able to reach your device.

Note: Resetting your network settings will erase any saved Wi-Fi networks and Bluetooth pairings, requiring you to re-enter them after the reset is complete.

To reset your network settings on most Android devices:

• Step 1: Open the Settings app on your smartphone, then tap System or General Management.
• Step 2: Go to Reset > Reset Network Settings and confirm the action.

6. Turn Off Bluetooth

When Bluetooth is on, it can interfere with your device’s ability to receive calls, causing them to go straight to voicemail without ringing. To turn off Bluetooth on an Android device, you can do one of the following:

• Swipe down from the top of the screen to open the Quick Settingspanel, then tap the Bluetooth icon to turn it off.

• Go to Settings> Connections > Bluetooth and toggle the switch off.

It should help ensure that calls come through to your phone instead of going to voicemail.

7. Check Airplane Mode

If turning off Bluetooth didn’t solve the issue, another possible cause could be that your phone is in Airplane Mode. Airplane Mode turns off all wireless connections on your phone, including cellular service, which can cause calls to dial straight to voicemail. There are two ways to turn off Airplane mode on Android:

Using the Settings app:

• Step 1: Open the Settings app.
• Step 2: Tap Network & internet.
• Step 3: Toggle off Airplane mode or Flight mode.

Using the Quick Settings panel:

• Step 1: Swipe down from the top of the phone screen to access the Quick Settings panel.
• Step 2: Look for the Airplane mode or Flight mode icon, then tap it to turn it off.

8. Check Blocked Numbers

“My boyfriend’s phone goes straight to voicemail when someone is calling. Any idea why that might be?”

Do you also find yourself asking what does it mean? It could be that he has blocked that phone number. To check this:

• Step 1: Open the Phone dialer app.
• Step 2: Tap the menu icon in the top right corner and select Settings.
• Step 3: Tap Block numbers. If you find the number in the blocked list, remove it to ensure that their calls come through to the phone.

If you still have trouble reaching your boyfriend, try calling him from a different number. If your call didn’t go through, you know that he hasn’t blocked your number and that there may be another issue with his phone.

9. Turn Off Google One VPN

If you’re using Google One VPN, try turning it off to see if that fixes the problem. Some users have reported that Google One VPN can cause incoming calls to a phone to go straight to voicemail. To turn off Google One VPN:

• Step 1: Open the Google One app on your Vivo Y78 5G.
• Step 2: At the bottom, go to the Benefits tab, then tap View Details below the Online protection with a VPN section.

• Step 3: Toggle off Enable VPN.

10. Contact Your Carrier

If your phone calls go straight to voicemail after trying all the above, contact your carrier for help. They may be able to troubleshoot the problem or determine if there is a service outage in your area.

And if your carrier confirms that there is no service outage or billing-related block, the problem may be with your phone itself. You may need to try resetting your phone to factory settings or taking it to a repair shop.

11. The Caller Used Ringless Voicemail

Ringless voicemail is a service that allows businesses to bypass your phone’s ringtone and send you pre-recorded messages directly to voicemail. Ringless voicemail is often used for marketing purposes. If you think you’re receiving ringless voicemail calls, you can contact the company calling you and ask them to remove you from their list.

Use static IP address instead of DHCP

DHCP, or Dynamic Host Configuration Protocol is the default IP address assignment for the Wi-Fi settings on many devices. Whereas DHCP can cause IP address conflict during the dynamic IP address assignment. So, you’d better change “DHCP” to “Static” to see if the authentication error persists.

Step 1: Head to the “Settings” of your Vivo Y78 5G and then opt for “Wireless and Networks” followed by “WLAN/WiFi”.

Step 2: Now, hit on the WiFi network that is showing “authentication error occurred”.

Modify network connection

If the above solution won’t work, then you would be required to walk the extra mile to fix the Vivo Y78 5G Wifi problem.
