Hello I bought a wireless bluetooth headphone set brand Nakazaki model BTH024. Whenever I pair the headphones I lose connection with my house wifi. I'm listening to music and then the wifi icon starts to show only the green arrow and then disappears. Then it appears again and says "Connected to xxxxx" It does this every minute if I'm surfing in the internet 
Version 4.3 root checker says its rooted yet I didn't do it, it was sold like this. If I upgrade the version will it be solved? The company I use is different that the cell phone, so if I upgrade I don't know what to do if I'm not allowed to use the company I'm using right now!
Help!
