    Hi, my video can’t be repaired. Tha app said that my internal storage or sd card might be corrupted. What should i do?

    • Magda Post authorReply

      Hi Yuda,
      If the problem with broken files appears often, You might double check your phone for hardware problems with SD card/internal memory.
      MP4Fix works if your videos are broken because of video application crashed, dead battery, lack of space.
      MP4Fix is not designed to fix hardware problems (This information can be found in description of MP4Fix on Play Store) ) but sometimes it works.
      Steps to take:
      1.remove the SD card
      2. The SD card can be inserting to the computer (through the adapter).
      3. Check if there are any large temporary file on SD card.
      4. In case you’re able to get crashed file that is not 0kB (by recovering some temporary files) MP4Fix may be able to fix it.
      5. Copy the broken file to a new SDcard before using MP4Fix.
      Also, you might like to change your SD card to the new one to prevent future problems with damaged files.
      Good luck!

    Hi guys.

    Im succes to fix my video, but suddenly I try to move the video that repaired to my laptop.. and i cant to watch that video.. “unknown error:

    How can i watch that video again? the format change to mp4fix.mp4

      To save your repaired videos Premium Features is necessary.
      You might try to watch your video on VLC – this video player provides probably the best codec support.

      Hi Bapin,
      The MP4Fix Video Repair Tool is 100% private. MP4Fix does not transfer any parts of crashed, working and fixed video files. Only statistics (file size, format, name) are gathered.
      The video is repaired on a smartphone with MP4Fix app installed and can be watched only there.
      Please find more info in Q&A section:

    the APP worked great! I look forward to leaving a great review. However when I click save it went to ” storage/emulated/0/Android/data” ETC. but when I look in my files on my phone I do not see that path and my phones gallery does not see the video or path . I can only play it with your app. Do i need to jail break my phone or something?

      Hi Nitro,
      I’m happy to hear you have a long list of recovered files:)
      This function is on our “todo” list and will be done in the future.

    hi mp4fix, can this apk be run offline, and when I uninstall the apk from my handphone all the statistics collected in your database will be automatically deleted.

    Thank You.
