I have noticed recently that the quality of the pictures my MX4pro takes is lower. On firmware 188.8.131.52 photos looked better and the size of them varied between 6 to 9 mb, while now, on 184.108.40.206 photos look average and their size rarely goes above 3 mb. Is it just me who’s noticing this?
Have you checked your camera settings? With some updates, I myself experienced the “picture quality” switched down to the lowest setting automatically after an update. First, check that, otherwise I can’t say much than try a 3rd party app (Maybe Google Camera or such) and try if that helps any.
