Good day, I am VERY disappointed with my Sony Xperia M5 that I bought more than a year ago. Since I bought this phone I have continues problems with it. At many times the phone would not switch on or off. When we have a power outage the phone goes off by itself and once the power comes back on, I find it difficult to switch my phone on again. When I'm in a building where the signal is low my phone switches itself off once again and I can't get it back on and have to wait till I'm home to put it on the charger in aid to switch the phone on again. I would never purchase any Sony phone again. I have had many phones in my life time but never had problems like I am having with this Sony phone. I would not even rate this phone 1 out of ten.
