I observed very weired random issue on my S25 Ultra...Once I call someone; mic is not getting activated and that i come to know when i saw that green indicator not coming on top once users accept call so voice is not getting heard at other end. I was thinking its network issue but its mic activation issue...if we click mic mute unmute then person at other end able to hear voice
By default in Samsung phone app microphone permission is not applied. I dont know how the app manage this... actually i have used other dialer as well and still face such random issue
Probably the cache or other dynamic files of that app r still there. Do 1 thing, Take backup of entire data, clear cache partition of ur phone and see. It should work.
Escalate the matter via Email to Samsung seniors tag consumer forum and also spread a word on Social media. For many users with vertical lines issue, these steps have worked.
In case the issue still occurs, kindly visit the service centre for a physical inspection of your device. You can locate your nearest service centre with this given link: https://www.samsung.com/in/support/service-center/
