As a longtime iphone user I was ready to switch when a TMobile rep asked how concerned I was about security and encryption. He said he doesn't recommend using banking apps on android. That freaked me out and made me change my mind on getting the S7E. What am I missing? I hear these phones have antivirus. I used to be on Windows and occasionally got viruses. Since being on an macs for 7 years we haven't had one virus. Was the TMobile rep right? He is an exclusive android guy too. He just said he doesn't bank on his phones.
