We suspect someone has a tracker on a friends phone. They have had access to the phone (samsung galaxy s2) as they bought her it and set it all up ready for her to use, but they slipped up in a conversation about an unrecieved text message saying the last time I got a message from her phone was 12am and we realised thats what time she had arrived home that night but she had'nt sent him a message 
Is there any way to check on her phone if there is a tracker set up on her phone?.
We know when he bought her the phone he told her there was a location tracker for if it is stolen, but he should'nt be getting messages to his phone telling him her location should he.
