20 month old phone. Tried replacing battery and changing power charging cables. Sometimes by wiggling charging cable I can get the orange charging light to blink about ten times then this stops. Won't turn on because no power. The few times I was able to get it to charge (randomly worked) it powered up fine but got super hot. Any suggestions? Not under warranty and we don't pay the replacement warranty program, so I am thinking I am out of a phone for the next four months. Don't want to upgrade to new phone cuz we want to switch from T-Mobile to another company when our two years is up in four months. Forgot to mention: It does not have a bumper/cover around it.
