By default, the quality should be just within what the accepted range is. However, there could be instances where we accidentally change or modify it.  

To revert it, go to Settings, then hit on the option that says PICTURE/IMAGE/VIDEO/QUALITY. The wording of the labels and options might be different, so try to find what best suits it.
