Sound of incoming SMS has started to disapper
The sound of incoming SMS of my iPhone has started to disapper sice yesterday (23 March). It only vibrates. I verify that all sounds are open from Setting, my iPhone is not at silent & I'm not using any apps. I've restarted the iPhone for once and I thought it probably solve it permantly. But it started to silent the sound of incoming SMS today again. Is there a solution? Music is still can be played from both speakers and headphones. Notifications also still have sound normally. Sound of incoming call... I don't know it yet. I didn't have any incoming calls yet. Probably it doesn't have any problem either, but will update here if I have one
