Symptoms
- Video call freezes mid-conversation
- App crashes and needs to be rejoined
- Call quality degrades before freezing
- Phone feels hot during the call
Likely causes
- CommonWeak or unstable internet connectionVideo calls need consistent bandwidth; drops in signal can cause freezes or crashes.
- CommonPhone overheating during a demanding, extended callVideo processing is resource-intensive and generates heat quickly.
- PossibleToo many other apps open in the backgroundMemory competition can cause the calling app to become unstable.
- PossibleOutdated app versionVideo call stability bugs are commonly patched.
- PossibleLow storage space interfering with app performanceSome apps need free space to buffer video temporarily.
What to do
- Check your Wi-Fi or cellular signal strength before and during calls.
- Close other apps running in the background before starting a video call.
- Update the calling app to the latest version.
- Free up storage space if it's low.
- Avoid direct sunlight and remove a thick case during long calls to reduce heat buildup.
- Restart the phone if calls have been unreliable across multiple attempts.
- Try an alternate network (switch Wi-Fi to cellular or vice versa) to isolate the cause.
When to call a pro
If video calls are unreliable across every app on a strong connection, a repair shop can check the phone's cooling and hardware performance.
