How to Install (3 Easy Steps)
1
Tap "Download APK" above
If your browser shows a warning saying "File might be harmful", tap Download anyway. This standard Android prompt appears for all apps downloaded outside Google Play.
2
Open the downloaded file & tap "Install"
Tap the download notification or find whocaller.apk in your Downloads folder. If prompted to allow installs from this source, enable it in Settings.
3
Open WhoCaller & grant permissions
Grant Phone, Contacts, and Call Log permissions when prompted. These are required to identify callers and block spam.
★
Set WhoCaller as your default dialer (optional)
For the best experience, make WhoCaller your default phone app. This enables incoming call screening, full-screen caller ID, and one-tap spam blocking.
