Why is my Samsung phone auto rejecting calls?

Samsung phones are still some of the most popular and reliable devices that you can opt for. But, there are still some issues that you can run into if you have an Android phone – your device auto rejecting calls is one of these.

Though uncommon, this can happen if you’re the owner of a Samsung. Here’s the most likely reasons why this will happen to you, and what you can do to fix it.

Why your Samsung phone is auto rejecting calls

Some users find that their Samsung phone will reject incoming calls for no reason – though realistically, there’s often an underlying reason that causing this. Typically, this is;

  • The number calling you has been blocked on your device
  • Your phone is in Airplane mode
  • Do Not Disturb mode has been enabled
  • You need to turn Call Barring off
  • Call forwarding may re-route an incoming call

You can easily block numbers and unblock them on your phone. We’ll take a quick look at how you can do this on your phone.

Check Your List of Blocked Numbers

The automatic reject function of a mobile phone is usually down to your blocked list, and if you have a number on your block list, then this will usually go straight to voicemail after one or two rings.

For Samsung phones, the auto rejection of the call based on blocked numbers can be disabled by opening the Phone app, and then going into your Settings.

Upon opening the app, you should be able to see the blocked list. You can then disable individual numbers for your Samsung smartphone. Check here if you want to know how you can see missed calls from blocked numbers on Android.

This is the most common reason, but there’s a few other reasons why your Samsung phone may auto reject calls.

Check Airplane or Flight mode on Android

Both iOS phones and Android phones will automatically reject calls if you have flight mode enabled on them. Flight mode essentially just disconnects your device from accessing its cellular data, meaning that you can neither make or receive calls.

This is one of the most common reasons that your Samsung phone will auto reject calls, so it’s important to ensure that airplane mode is disabled on your device.

Do Not Disturb Mode has been enabled

Not all Android phones have Do Not Disturb mode, but if you do, it may stop you from receiving calls. This is intentional, as when it’s enabled it’ll ensure that messages don’t give notifications, and calls will be sent straight through to answerphone.

You should be able to easily turn this on and off by simply swiping down on your phone, which should bring up the Do Not Disturb option. You can toggle this on and off if you want to allow calls through to your device.

Disable call barring

Call barring is a common feature that you can find on Samsung devices. Usually, you’ll have to activate this yourself if you want it to be enabled. However, you may also find that call barring is on randomly.

You can typically find call barring located within the settings menu in your Phone app, sometimes listed under Supplementary services. Once you select Call Barring, you’ll be able to enabled or disable this feature (if you have a dual SIM phone, you can select which SIM to enable).

Call forwarding is enabled

Often, your Samsung phone will forward calls from one phone to another phone or voicemail address.

Call forwarding can be extremely useful if you want to send calls to another mobile phone automatically, but it means that you won’t be able to answer directly on your current handset.

Deactivating forwarding calls can easily be done within the Settings app on your Android device. This will stop the call from being redirected and you’ll be able to pick it upon your phone.


In conclusion, there’s a few different reasons why your Samsung phone may be automatically rejecting calls from your device.

This is largely down to the own settings that you have enabled on your phone, and by adjusting them, you can usually get this issue resolved.
