I am expressing my disappointment in buying Sony Xperia C4. I had just bought it a year ago and it had gone a lot of malfunctioning now it is only used as a paper weight. Though I commend their support team. I feel like the product isn't worth buying. A few months ago the touch screen did not work properly,and i have heard, it was not an isolated case. Luckily, it was covered by the warranty. Weeka later, after the release of the new software , marshmallow, it had gone malfunctioning again. It shut downs by itself. I was advised to do a software repair. Yet it is still malfunctioning. The software repair was successful but It won't turn on properly now. It will continuously turn on and then shut down.
try to search about the topic "BOOT LOOP" on the search bar above,. and perform software repair using Xperia Companion once more time.
if that doesn't work try to send your device again for repairs Local support
