BEWARE! Can be used by scammers. I had a very convincing member of virgin media who claimed I hadn't been getting the speed I pay for so was due compensation. With this installed and a banking app they took £2500 out my account before I could even hit the back key. They had full control of my device and all info to con me. Quoted me Bill's I pay and account which was all part of their clever scam. I've spent 6hrs at the bank and talking to the fraud squad who have refunded my money. Be careful
