4 Android-Specific Mistakes to Avoid
⚠️ Not disabling battery optimization for your calling app
Android's Doze mode kills background apps to save battery. This means you'll miss incoming calls if the app isn't excluded. Go to Settings → Battery → Battery Optimization → select your calling app → Don't Optimize.
⚠️ Downloading random 'free call' apps from the Play Store
The Play Store is full of fake calling apps that force 15+ ads per minute of calling, harvest your contacts, or require you to earn coins. Stick to established apps — the 8 on this list are all from legitimate companies.
⚠️ Assuming WhatsApp calls use your phone minutes
WhatsApp calls use Wi-Fi or data, not cellular minutes. They're completely free and don't count against your phone plan. Many Android users don't realize this and avoid WhatsApp calls unnecessarily.
⚠️ Not granting microphone permissions properly
If an app can't access your microphone, calls will connect but the other person won't hear you. Go to Settings → Apps → [calling app] → Permissions → Microphone → Allow. This is the #1 support ticket for every calling app.
