Check the connection
Confirm you're online. Toggle Wi-Fi and mobile data, move to better signal, and turn off any VPN or data-saver that might be throttling the app.
Troubleshooting
ChatGPT app not working? Start here.
When the ChatGPT app won't load, freezes mid-answer, loops on login or drops your voice chat, the cause is almost always one of a short list: connection, an outdated app, a login snag, or an outage. This symptom-to-fix guide walks each one in order — the quick toggles first, then reinstall and outage checks.
Symptom → fix
Find your problem, get the fix
Match your symptom in the left column and work through the fix on the right. Most issues clear in the first two rows.
| Symptom | Try this |
|---|---|
| Won't load / blank screen | Check your connection, toggle Wi-Fi and mobile data, turn off any VPN, then force-close and reopen the app. |
| Stuck generating | Stop the reply and retry, switch networks, send a shorter prompt, and update the app if it keeps hanging. |
| Login loop | Update the app, switch networks, disable VPN, and sign in again. If it persists, reset your password or reinstall. |
| Voice not working | Grant microphone access in settings, check the connection, update the app, and reopen voice mode. |
| App keeps crashing | Update the app, restart your phone, free up storage, and reinstall if crashes continue. |
| Down for everyone | Check status.openai.com. During an outage, waiting is the only fix. |

In order
The universal fix sequence
If you're not sure which symptom you have, run these steps top to bottom. They resolve the large majority of app problems.
Force-close & reopen
Swipe the app away from the recents view and open it fresh. This clears a stuck session without touching your data.
Update the app
Open the App Store or Google Play, search ChatGPT, and tap Update. An outdated app is a common cause of crashes and login loops.
Restart your phone
A full restart clears memory and refreshes network connections, which fixes a surprising number of freezes and voice glitches.
Check the status page
Visit status.openai.com. If ChatGPT is reporting an outage, the problem isn't your phone — wait it out.
Reinstall as a last resort
Delete the app and install the genuine version again from the store, then sign in. Your history returns with your account.
Trickier cases
Login loops, voice and outages
A few symptoms need a slightly different approach. Here's what to do when the basics don't clear it.
| Case | Extra steps |
|---|---|
| Login loop won't clear | Confirm you're using the same sign-in method as before (Apple, Google, Microsoft or email). Reset your password on OpenAI's site, then reinstall for a clean session. |
| Voice starts then drops | Re-check microphone permission, ensure a stable connection, and note that Advanced Voice can hit plan limits. See the voice guide. |
| Slow only on mobile data | Disable data saver for ChatGPT, check background-data settings, and test on Wi-Fi to isolate the network. |
| "App outdated" message | Update immediately; older versions can be blocked. If no update appears, your OS may be too old — check requirements. |
| Errors for everyone | Confirm on the status page. Reinstalling or resetting won't fix a server-side outage. |

FAQ
ChatGPT app fixes — questions
Why won't the ChatGPT app load or open?
A blank screen or spinning loader is usually a connection or server issue. Check your internet, toggle between Wi-Fi and mobile data, and disable a VPN if one is active. Force-close the app and reopen it, and restart your phone if it persists. If ChatGPT is down for everyone, the status page will show it, so waiting is the fix.
Why is ChatGPT stuck generating a response?
If a reply hangs or the typing indicator never finishes, it is often a weak connection or heavy server load. Stop the response and try again, switch networks, and send a shorter prompt. If it keeps stalling across chats, the service may be degraded; check the status page. Updating the app can also clear generation bugs.
How do I fix a ChatGPT login loop?
Login loops, where sign-in keeps returning you to the login screen, often clear after updating the app and checking your connection. Try switching networks, disabling a VPN, and signing in again. If it continues, reset your password from OpenAI's site, or uninstall and reinstall the app so it starts a clean session. Confirm you are using the same login method as before.
Why isn't ChatGPT voice mode working?
Voice problems usually come down to microphone permission, connection or a temporary outage. Check that the app has microphone access in your phone settings, ensure you have a stable connection, and update the app. Advanced Voice can also hit plan limits. Close and reopen voice mode, and if the whole service is down, wait and retry.
Why does the ChatGPT app keep crashing?
Repeated crashes are often fixed by updating the app, restarting your phone and freeing up storage. An outdated app version or low memory can cause instability. If it still crashes, uninstall and reinstall the app. On very old phones the latest version may run poorly, so check that your operating system is supported.
How do I know if ChatGPT is down?
If the app fails for everyone at once, it is likely an outage rather than your device. Check OpenAI's official status page at status.openai.com to see whether ChatGPT or the API is reporting problems. During an outage the only fix is to wait for OpenAI to resolve it; reinstalling or resetting will not help.
How do I update or reinstall the ChatGPT app?
To update, open the App Store or Google Play, search for ChatGPT and tap Update if available. To reinstall, delete the app from your home screen or app settings, then download the genuine app again from the store and sign back in. Your history is tied to your account, so it returns after you log in. Only reinstall the official app from OpenAI.
Why is ChatGPT slow or not responding on mobile data?
Slow or failed responses on mobile data often mean a weak signal, network congestion or a data-saver setting throttling the app. Move to better coverage, disable data saver for ChatGPT, or switch to Wi-Fi. If the app works on Wi-Fi but not mobile data, check your carrier settings and any restrictions on background data for the app.
Do I lose my chat history if I reinstall the app?
No, as long as you sign back in with the same account. Your conversation history is stored with your account and synced, so reinstalling the app and logging in restores it. Anything you deleted before reinstalling stays deleted. If history seems missing after signing in, check that you used the correct login method and account.
