I rarely install anything, but it also started happening to me, after installing an app advertisen on Instagram.
(Pretty Lockscreens or something like that)
It wanted to send some sms messages to strange looking number, and i immediatly uninstalled it.
Messages had 'fail' status fortunetly.
After that, when i unlock my phone, bluetooth turns itself off (like it suddenly notices me unlockimg my phone), but sometimes it fails to detect my action and it stays on.
Just for the record, I never use Bluetooth and it supposed to stay off all the time.
I scanned my phone using Avast antivirus several times, but nothing suspicious was found...
