Frequency of Occurrence: Always
Rooted: No
APP Name: Bluetooth aptx
Hi,
I recently updated to the 059 firmware and noticed that Bluetooth sound quality significantly decreases as well as max volume is too low.
I am using headphones that support aptx (I see notification that it is turned on). I am comparing sound using same apps/same file on my Asus phone, old iPad and Windows laptop. Both quality and max volume are way worse on Asus phone which was not the case before.
What I have done so far:
- tried to 'Disable Absolute volume' in Dev settings
- reset Bluetooth/wifi settings
- reset all apps settings
Still no luck. Moreover it also sounds as if left/right channels are not balanced. And it also sounds that switching Aptx on and off (in Bluetooth settings) does not affect sound quality at all - therefore my guess would be that aptx is not working (although shows to be active).
I was trying to see HCI log - but it's not working - no log file is produced to further investigate the issue.
Thank you in advance for your help.
