The Sony Xperia Z5 received the Nougat updated sometime in mid-January but it was quickly halted after a few days due to various bugs and issues. Despite the OEM resuming the OS roll out last month, the issue of “low in-call volume” has not been rectified.
Thankfully, Sony has acknowledged this issue and said that it will release a fix for the issue next month. The manufacturer will kick off an OTA update in mid-April to rectify this problem.
In Sony’s official statement, it revealed that a temporary solution is “to perform a factory data reset. Please make sure that you backup data stored on the internal storage that you want to keep before performing a factory data reset.”
It added that, “The speaker calibration starts the first time you are using the speaker, and later requires that the loud speaker is idle for 30 minutes. The calibration is completed after up to ten hours.”
Well, it looks like there’s no other way – Sony Xperiz Z5 users would have to wait one more month before the next update that fixes the low volume issue caused by Nougat.
