I've had this phone for a few years now without problems but experiencing problems the past 3 days. I turned it on one day and a yellow screen appeared with "Emergency Mode" I turned off the phone, removed the battery, put it back in. Turned on the phone.... LG logo showed up, screen went blank. Did this twice. It finally came on but showed the battery was low on power. I charged it for several hours yesterday . Today I turned on the power and the battery is still low and message saying to plug it in. What should I or need to do? Factory reset it? Or call Koodo? Thanks!
