Lately, my Spectrum has had some trouble charging. I have to get the charger in there just right to get it to charge. Sometimes when charging it says it is slow charging even though I am using a wall charger. Also, when I charge at work, I use my computer, it will charge but cannot switch to mass storage. In fact I usually get a warning saying it cannot recognize my device. Is this common with the Spectrum? I have a year till my upgrade so I hope my phone isn't starting to die. Thoughts?
