My Samsung GT-I8150 is sending a text message after every reboot witch is not appearing at all in the sms area of the phone. The phone is rooted and has cyanogen mod 9 installed.

I think someone at work/at home got into my phone and installed some hidden tracker. How can I detect this and also prevent this?


  • How do you know it's sending a text message? – geffchang Sep 30 '13 at 13:54
  • @geffchang a small pop-up in the down-side of the screen appears saying "Your message has been sent". This is the normal behaviour of my phone when sending a regular wanted message. – Octavian Sep 30 '13 at 14:21
  • Do you ever get any text/reply from the recipient after the message was sent? – geffchang Sep 30 '13 at 14:55
  • No, and I cant even see the recipient. – Octavian Sep 30 '13 at 18:35

Sounds more like a virus. The only guarenteed way is to flash a fresh ROM and start over. Malware is getting smarter and smarter and may be able to hide itself on the OS unless you start fresh.
