I have an S23 Ultra 512gb. Recently my phone has had a crackling speaker, I’ve tried to blow it out with air compressor and done the recent update to try and fix but it still crackles. Only got the phone in June. What could this be? Also my battery has been decreasing 30% overnight when not on charge. Any help would be appreciated, thank you.
Have you tried removing the sim tray? It happened once to my S23+ somehow it got over pressurized inside and after removing the sim tray the speakers were back to normal
Also relating to the battery, what apps are draining your battery? Does it show anything in the settings menu?
