I am using HTC One M8 since 2013. I love this phone n now it is more comfortable with new version update marshmellow 6.0.1. It’s picture clarity is so good hd quality n sound is the best with HTC Boom Sound feature. Internet speed is best with 4G n wifi. Easy to use n easy to handle with metalic body. Camera gives best quality hd pictures n videos. Without any complaint I am using this phone since 2013 n recommend to you guys to have this best phone with latest features
