Phone died while recording? Fix a corrupted iPhone or Android video
You were recording a concert, a recital, a once-only moment — and the phone hit 0% and shut off. Now the video sits in your gallery as a black thumbnail that won't load. Before paying anyone or uploading anything, try the built-in fixes. They're free and they often work.
iPhone: let iOS fix it overnight
iOS can finalize interrupted recordings in the background once the phone has stable power. The routine that works for many people:
- Plug the phone in and leave it charging.
- Leave it powered on, connected to Wi-Fi, and idle overnight.
- Check the video in the morning — a black-thumbnail clip frequently plays normally after the background repair runs.
Don't delete the clip, don't offload it to iCloud, and don't edit it while it's broken — give iOS a day with it first.
Android: screen recordings and camera clips
When the battery dies or the recorder app crashes, the MP4 is left unfinalized — same story as an OBS crash on a PC. Some gallery apps attempt a silent repair; give the phone a restart and a charge first. If the clip still won't play:
- Copy the file to a PC with a USB cable — don't rely on cloud sync, which may transcode or skip the broken file.
- Record a 10-second healthy clip with the same app and settings (same resolution/frame rate) — this is your reference.
- Rebuild the broken file's index using the reference-file method.
Transferred file broken, original fine? If the copy on your PC won't play but the phone's copy does, the transfer was interrupted — just re-copy with a cable. No repair needed.
Repair private phone videos — without uploading them
Family moments don't belong on a stranger's server. StreamSalvage rebuilds the video on your own PC from a short reference clip: free preview, $29 only if it works, nothing uploaded.

- Don't start long recordings below ~20% battery — low-voltage shutdowns mid-write are the classic cause.
- Free up storage first; a full disk mid-recording truncates the file the same way a dead battery does.
- For long events, plug into a power bank while recording.
Frequently asked questions
My iPhone died while recording and the video is a black thumbnail. Is it gone?
Often no. Charge the phone and leave it powered on and idle overnight — iOS can finalize interrupted recordings in the background once stable power returns. Many users find the video plays normally the next morning. If it's still broken after a day, move to PC-based repair.
How do I fix a corrupted screen recording on Android?
If the recorder crashed or the phone died, the MP4 was never finalized. Copy the file to a computer via USB cable, record a short healthy clip with the same recorder and settings as a reference, and rebuild the file's index with a reference-file repair tool.
Why did transferring the video corrupt it?
Interrupting a USB transfer or a cloud sync can truncate the file, cutting off the index at the end. Check whether the original on the phone still plays — if it does, simply re-transfer it with a cable and don't disconnect mid-copy.
Can I repair a phone video without uploading it to a website?
Yes. Copy the broken video and a short healthy clip (same phone, same camera settings) to a Windows PC and repair it locally. StreamSalvage rebuilds the index on your machine with a free preview — private videos never leave your computer.
