How To... fix your Samsung Galaxy S6 if it won't charge
If you've been using your Samsung Galaxy S6, but found that you're having trouble charging it, or turning it on, don't worry! We've got a fix for you.
Check Your Charger & Socket
This is an obvious one, but make sure your charger is working. If you haven't got a spare charger from an old Android phone, then someone else will have one. They're universal, so anyone with an Android phone can let you use theirs to check.
Make sure you use an official one if you're buying a new one. There's a load of dodgy cheap ones on the market which can wreck your phone, or just not work so you're wasting your money.
Also, try different sockets in your house. If you always leave your charger plugged into the same socket next to your bed or whatever, try it somewhere else to see if the socket is the problem. Also, take the USB lead from the charger and try charging your phone through a computer or whatever.
Check The Charging Port
Have you got a bit of biscuit stuck in the slot on your phone, so your charger isn't connecting properly? Has some lint from your pocket or bag got in there? Have a look and try and get it out with some tweezers or a pin. Be gentle though. You can also buy compressed air in cans, and blow all the nonsense out of there or buy a mini hoover vacuum and suck it out (great for the gunk out of keyboards).
Fix The Port Yourself
Just through use, sometimes the port can need a little repair as the metallic surfaces inside the USB port and the microUSB charger aren't contacting properly. You can have a go at fixing that pretty easily.
First, turn your phone off and remove the battery. Then, get something small and sturdy (a toothpick should do it) and get a little leverage on the little tab inside the USB port. Be very careful and gentle, and then pop your battery back in, and see if it starts charging when you plug it in. Most of the time, this should solve the problem.
Sometimes, a software update can be the cause of the bother. If that's the case, you can restore your phone to a previous version of Android when everything worked. This isn't an ideal fix, as manufacturers are keen for you to have the latest versions, as they're more secure. That said, the difference is usually negligible.
Contact Your Provider
Here's the most obvious one - get in touch with the people you got your phone from and tell them it doesn't work properly. They should be able to provide you with a solution. If you're not confident tinkering around with your phone, then this is your best bet. Again, it isn't exactly ideal, but this is the safest option.
