G.O.A.T Detective: 0
🚀
  • Unexpected Network Errors – Calls dropping right after answering due to weak signals or carrier-side disruptions.
  • Software Bugs & Recent Updates – A glitch in a system update can interfere with call stability.
  • Accumulated SIM Toolkit Data – Corrupt SIM toolkit data can cause auto-call disconnections.
  • Ghost Touch Issues – Phantom screen touches triggering the end call button unintentionally.
  • Overheating & Processor Throttling – Phones may automatically close processes to cool down.
  • Low RAM & Storage Capacity – Background apps overwhelming system resources, leading to unexpected shutdowns.
  • Faulty Proximity Sensor – A misfiring sensor that falsely detects movement away from the ear can disconnect calls.
  • Carrier Call Filtering – Some networks auto-drop calls they suspect as spam, even from legitimate contacts.
  • Modded or Third-Party Apps – Unauthorized modified apps can interfere with call permissions and cause unexpected call drops.

How I Fixed My Phone Hanging Up By Itself

1. Restart Your Device

phone updates

I know it sounds basic, but restarting twice actually fixed this issue for some users by refreshing network and system connections.

2. Check for Software Updates

A buggy update can disrupt call stability. Head to Settings > System > Software Update and install the latest version.

3. Disable Battery Optimization for the Dialer App

Battery optimization aggressively kills background processes—including the dialer.

  • Android: Settings > Apps > Dialer > Battery > Disable battery optimization.

Reddit user u/PocoDude94 confirmed this stopped their random call hang-ups entirely.

4. Clear Cache and SIM Toolkit Data

Your phone’s SIM toolkit accumulates background data that may corrupt call handling.

  • Android: Settings > Apps > SIM Toolkit > Clear Cache & Data.
  • iPhone: Reset carrier settings via Settings > General > Reset > Reset Network Settings.

5. Turn Airplane Mode ON & OFF

A simple but powerful trick—toggle Airplane Mode ON for 30 seconds, then OFF to force a network reconnection.

6. Remove and Reinsert Your SIM Card

A faulty or misaligned SIM card can interfere with network connectivity. Remove the SIM, clean its metal contacts, and reinsert it.

7. Check for Overheating Issues

I noticed that my phone hung up after long calls—it was overheating, which triggered automatic shutdowns.

  • Avoid using power-hungry apps while on a call.
  • Remove your phone case to help it cool down.
  • Let the phone rest for a few minutes if it feels too hot.

8. Reset Network Settings

A corrupted network profile can cause call disruptions. Resetting network settings can restore default carrier configurations.

  • Android: Settings > System > Reset > Reset Network Settings.
  • iPhone: Settings > General > Transfer or Reset iPhone > Reset Network Settings.

9. Test in Safe Mode

Some apps may interfere with your phone’s ability to maintain calls. Running in Safe Mode can identify the issue.

  • Android: Hold the power button, then long-press Power Off and select Safe Mode.
  • iPhone: Disable third-party apps manually and test your calls.

Why Does My Phone Hang Up When I Answer?

🔹 Some devices mistakenly detect a double-tap gesture, which causes the call to hang up.
🔹 A faulty screen protector or ghost touch issue could be triggering the End Call button.
🔹 Recently installed apps modifying call behavior can interfere—uninstall them and check if the issue stops.
🔹 Network instability can also be the cause. Try switching from VoLTE to 3G mode to see if it helps.


Hidden Causes You Won’t Find on Google

lets go

💡 Carrier-Level Call Blocking – Some mobile carriers detect certain call patterns as “suspicious” and block calls automatically. If this happens only with specific contacts, call your carrier and ask them to whitelist numbers.

💡 RF Interference from Bluetooth or Wi-Fi – If you always experience call drops in a particular area, your device may be affected by environmental radio frequency (RF) interference. Turn Bluetooth & Wi-Fi off and test again.

💡 Processor Throttling Due to Thermal Limits – Some budget phones with Snapdragon or MediaTek processors throttle CPU usage when overheating, leading to call interruptions. Check your device’s temperature while on a call.

💡 Modded Apps & Third-Party APKs – Installing modded or third-party dialer apps can interfere with your phone’s call handling. Many modded apps request excessive permissions, override system settings, and can cause random call disconnections. If you’ve installed any modified or unofficial apps, remove them immediately and test if the issue is resolved.
