I have Nexus 5, KitKat 4.4.4 and it's making this weird sound. (soundcloud.com/artemissia/what-the-hell-is-this-sound)
It starts by itself, sometimes when trying to make a call or even for no apparent reason. Sometimes it just sounds once, sometimes it repeats itself insanely. I have restored my device, just in case I installed something that's setting it on, but even after that, without installing ANYTHING that wasn't on the original Google pack, it started AGAIN!!! arghhhhhhhhhh!!!!!!!!!! it's so annoying! can you please help me before I lose my mind entirely?
I need to mention that it began about 4 months ago. I moved from Israel (where it never happened) to UK and it started a few weeks afterwards. I don't know if it has anything to do with it. Anyways, my carrier is GiffGaff.
Thanks a lot for your help. I really appreciate it.
