Enhancement of blocking spam calls.

Enhanced blocking and fixing blocking failure due to Android OS update.

Due to Android OS update, some users are unable to block calls properly. Call Defender v.7.4.0 has a major upgrade to not only solve the blocking failure problem but also enhance the original blocking feature.

The new blocking feature will allow you to block calls without any rings or vibrations from your phone*, and smartwatches won't display any call notifications.

[Blocking Settings & Exceptions] > [Set as the default phone app] > [SET UP] > [SET DEFAULT]
Don't worry! It will not make any changes to your calling screen interface.

Since it is a major upgrade, there may be some unpredictable problems. Please use [About us] to report any failures or issues. We will try our best to solve the problem.

*Only when choosing [Block Call] in [Spam Detection Action]
