Sound quality too cheap: For the sound quality problem, could you tell us does this appear on wired earphone/bluetooth headphones/phone's speaker? What app/app version are you using? Do you have a music link you can provide as an example? Could you describe in more details about the sound quality problem?
low volume problem: Does this appear on wired earphone/bluetooth headphones/phone's speaker? Does it appear on system notification/ringtone/media? If media, what app/app version are you using?
