My Samsung Brightside all of a sudden from one day to next will not turn off anymore, only way I can turn off is by removing battery. Also when I do charge it and remove charger the phone will keep charging even though charger is disconnected. I had this problem with another Brightside previously and just got rid of it for another one. Now this one is doing same thing and nothing has happened to it, no water damage, no dropping, etc. I take really good care of my phones and I don't want to buy another one again. Does anyone have any suggestions as I love this phone and do not want to upgrade to smart phone too expensive. Thank you!
