My kids seem to be going through tablets constantly. Several Amazon fire’s and a couple of these DigiLand tablets. All models have the same type of charging port and that’s always the problem. They stop charging, it’s impossible to keep the charger plugged into it, or the little flat piece inside the micro usb is loose or broken. I know it’s from the constant plugging and unplugging on the fly and done improperly. I can’t break them of it! But I’m tired of buying new tablets…I want to fix this on my own. Are all micro usb ports on Amazon the same that I can just purchase any one…or are they specific? How do you replace them?
