Device description:

  • Hardware: LenovoPad YOGA Table 2-1050L
  • Operating System: Android 5.0.1
  • Application: WhatsApp both 2.20.189 and (newest from web, unavailable through google play)

Problematic, fine JPGs and exif:

Reproduction steps:

  1. On WhatsApp chat screen - Add Attachment
  2. On Attachment source selection - Gallery
  3. In Gallery - select specific problematic JPG
  4. Gallery redirects to "Add a caption" screen which redirects back to Gallery/Chat (depending on Gallery) after few seconds (<3 s).
  5. Some galleries show "The file format is not supported." in a Toast UI Element after redirection.

Taken steps to mitigate:

  • reinstall android from 4.x.x to 5.0.1
  • reinstall WhatsApp, clear data & cache, restore backup
  • upgrade to newest WhatsApp version not yet made available through Google Play from offial site
  • sending from sharing options of different galleries fails after selecting recipient in WhatsApp on Step 4)


  • sending as a Document (Step 2. - Document) works
  • sending from Samsung Galaxy S5, Android 6.0.1, WhatsApp 2.20.189 to mentioned device works
  • sending, resolution scaled down to >78% fails BUT to <=78% works WHILE taking a photo with much higher resolution and sending it works
  • sending, with minor change from built in gallery editor (which also scales down resolution), works
  • sending different JPG taken in a same day with the same camera with higher resolution works
  • sending photo taken by camera works
  • sending from external/internal storage fails

Example solution:

  • process affected JPGs in a batch processing software with minimal impact on quality (do not want to scale down to <=78%)
  • software fix

Please help. My next step would be attaching debugger or scaling down every photo >_<.
