Like the title says I noticed a few days ago that LDAC is not working anymore. It had been working perfectly since I bought the phone in December with android 7.1 and 8.0. Don't know if it's due to the July patch or the 8.1 update. Is anybody else having this problem? I use Sony headphones with this codec and the Sony application tells me which codec is being used. I noticed that whereas before I was using LDAC now it's using AAC. Does anybody know of a fix?
