Bug: I have uploaded an image (jpeg, 2,32MB, 3264x2448, 8MP) to private chat. There I have downloaded it again and I checked details of the pic: jpeg, but now 3,17MB, 3264x2448, 8MP, Exif-info got lost).

  2. Download image again and check details
  3. File is now bigger than before

Additional information: The image-processing by webapp (upload by browser) is much better. The by browser upload processed file is after download only half sized. Same procedure must be in native Android app.
