Help Random bleep sound while phone just sits on end table?

[reisb]

I can't seem to figure out where to turn this off. It happens a couple of times a day, sometimes in the middle of the night while sleeping. Phone is sitting on table, nobody around, and it makes a bleep sound one time. I check phone and no new notifications. Nothing.

Sometimes, I notice it says "searching for location" and then goes away. I'm not in a bad cell service area, but if that's what happening for a second, I need to turn it off.

Any ideas how to turn this off?

Setting/Location and then turn it off.

Turn location (GPS) off? That can't be it. I use my GPS daily. So I would need to turn it on and off every night? Seems odd...

I haven't noticed it when the phone is face down. Could it be one of those motion sensors setting off a search?

Now that I think about it, it's the same bleep sound it makes when I hit speaker on keyboard to use voice text or Google now voice search.

Where would those settings be?
