Hello, I've been having trouble with my Nexus 5. This is the second phone that has shut off on me and gotten stuck in a boot loop. I'm getting it replaced again, however I'm worried it might happen again with the new one, since it already happened twice. Since I am getting it replaced, could someone tell me what it could be doing this? As well as ways to try to prevent it? I just got this replacement 2 months ago, and am still paying for the phone I've already tried pressing the power button and the volume down key, as well as power and volume up, and all three together and individually, but none work. Also, it only loops when it's plugged in, and it does it from the moment it's plugged in, to the moment it is unplugged. When it's not plugged in, it won't do anything. I really appreciate anyone who helps me, and if you need any other information I'll try to get it.
