Are Your Snapchat Calls Failing?
Sometimes calls don’t go through on Snapchat, either because of a weak internet connection, outdated app version, permissions problems, or blocked contacts. Below are updated troubleshooting methods to get your Snapchat calls working properly again.
Ensure You Have a Strong Internet Connection
- Switch between Wi-Fi and mobile data to test which works better. If possible, try using a different Wi-Fi network.
- If using mobile data (3G/4G/5G), check your signal strength and data limit. If connectivity is spotty, moving closer to a window or outside may help.
- Resetting your router or modem can fix network issues. Also try toggling Airplane Mode off and on to refresh mobile network.
- Use apps like Speedtest to confirm latency, packet loss, and bandwidth. High latency or packet loss often causes voice/video drops.
Restart Your Phone
- Soft restart: power off completely, wait ~30 seconds, then turn back on.
- Hard restart / force reboot: use this if normal restart doesn’t help, especially when the device becomes unresponsive.
Update Snapchat and Your OS
Bugs are often fixed in updates. Ensure both Snapchat and your device’s operating system are up to date to avoid compatibility issues.
Check for updates on iPhone:
- Open the App Store.
- Tap your profile icon in the top right.
- Scroll to see if Snapchat has an update available.
- If yes, tap Update.
Check for updates on Android:
- 1.Open the Google Play Store.
- 2.Tap your profile icon at the top right.
- 3.Select Manage apps & devices.
- 4.Look under “Update available.”
- 5.Tap Update if Snapchat is listed.
Check Microphone and Permissions Settings
Failing Snapchat calls sometimes come from the app being blocked from accessing your microphone, or mic being muted or malfunctioning.
- On iPhone: go to Settings ▶ Privacy & Security ▶ Microphone and make sure Snapchat is allowed. Also check Settings ▶ Snapchat ▶ Microphone/Camera.
- On Android: Settings ▶ Apps ▶ Snapchat ▶ Permissions, ensure mic and camera permissions are granted.
- If using Bluetooth headphones or external mics, ensure they are connected properly and the mic input is not being misrouted. Sometimes switching off Bluetooth and using the phone’s internal mic helps.
- Check whether the phone’s mute/silent switch is on (iPhone) or media volume is very low. Sometimes volume being very low/muted prevents people from hearing you.
Clear Cache and Free Up Storage Space
Corrupted cache or low storage often causes Snapchat features (calls, video, etc.) to misbehave.
- On Android: Settings ▶ Apps ▶ Snapchat ▶ Storage ▶ Clear Cache. If issues persist, Clear Data (but this logs you out).
- On both iPhone & Android: inside Snapchat, go to your profile ▶ gear icon ▶ Scroll to Clear Cache (this won’t delete your chats or memories).
- Check overall device free storage; delete old media/files/apps you don’t need. Low storage can degrade app performance.
Ensure Contact Is Not Blocked and Permissions in Snapchat
- Open Snapchat, go to your profile, tap the gear icon for Settings.
- Scroll to Blocked and see if the person you’re calling is in there, if yes, unblock them.
- Inside Snapchat call settings: verify that camera and mic permissions are enabled for calls (video vs voice mode). Some users have reported issues when switching between voice call mode and video call mode without permissions for one of them.
Turn On Cellular Data for Snapchat
If you're on mobile data instead of Wi-Fi, confirm that Snapchat is allowed to use cellular data. If it's restricted, calls may fail.
- Go to Settings ▶ Cellular / Mobile Data ▶ Snapchat and toggle on data access.
- Also check whether there are any data saver / low data / background restrictions on Snapchat, it might be blocked in the background.
Restart the App and Re-Login
- Completely close Snapchat (swipe away / kill process), then reopen it.
- Log out and then log back in to reset session tokens, which sometimes go bad and prevent features from working.
Delete and Reinstall Snapchat
If nothing else works, uninstall Snapchat and then reinstall from a trusted source (App Store or Google Play). This ensures you have a clean install without corrupted files.
Check If Snapchat Servers Are Down or Having Issues
Sometimes the problem is not on your end. Snapchat could be having server outages or maintenance.
- Check Snapchat System Status for known issues.
- Look on Twitter / X or Reddit to see if others are reporting similar issues.
Update Device-Level Settings and Extra Fixes
- Disable Background Noise Suppression / Call Audio Enhancements – On iOS, go to Settings ▶ Accessibility ▶ Audio/Visual ▶ Phone Noise Cancellation and disable it. On Android, look for noise reduction settings in device sound/accessibility options. This can sometimes interfere with Snapchat’s call audio.
- Check for Mic Mode Glitches – Some users report that mic mode gets turned off for Snapchat specifically. Go to your phone’s privacy settings, microphone settings and ensure no system glitch or setting is disabling Snapchat’s mic.
- Volume and Silent Switch – On iPhones, ensure the physical mute switch is not silencing calls, and press volume up to increase media/call volume. On Android, check that media/call volume levels are not turned down.
- Inspect Hardware Issues – If your microphone is blocked by dirt, debris, or your phone case, clean it. If you suspect hardware damage (dropped phone, water damage), test the mic in voice memo / other apps to see if it’s working elsewhere.
FAQs
Why are my Snapchat calls failing
Common causes include weak or unstable internet, outdated app or OS, missing permissions (especially microphone), blocked contacts, low storage, or Snapchat itself having server issues.
How do I unblock someone on Snapchat
Go to your profile ▶ Settings (gear icon) ▶ Blocked. Tap the person you want to unblock.
Does clearing Snapchat cache delete my data
No, clearing cache removes temporary files but keeps account data, chats, memories, login info intact. However, clearing app data (on Android) or deleting & reinstalling will remove login/temporary settings.
Do I need to uninstall the app if calls fail
Not always. Try the other methods first (internet, update, permissions). Only uninstall/reinstall if those fail.
