Whenever I'm taking picture, i always get this pop up on my phone "Error. Could not save photos. There may be a problem with the data storage. If Data storage is set to SD card, please check your SD card". Out of 29.71GB, only 19.97 was used. Ahhrrgg! I'm so frustrated with this! Please help. I've already tried to eject the SD and restarted my phone (xperia 3z) but same error keeps coming. How can I fix this? I badly need help pleasseeeee.
