Answer to: My micro usb port isnt working anymorecheapest and easiest way to fix it for someone with basic soldering skills is to put a QI charging circuit into it to bypass the broken usb port. you need the 2000mA charging pad circuit then the 1000mA receiver usually off ebay for around ten pounds for both. you have to split the case and solder two fine wires to the battery terminals then to the receiver, the wires need to be long enough to fit around the copper sheet on the back panel so it can be closed up again. just make sure you get the polarity right and the pad the correct way around. the charger unit can then be lined up and either taped onto the back or sewn into a suitable case like the fintie slate 7 case or one of the chinese clones. I've got four of these (all bought broken off ebay) using this mod and all work fine, I have broken the ports on two of the chargers but you just put new ones in as a fiver a year is not much to pay. if you want a very simple way to get it working again you can also split down a regular usb cable and solder the bla...
Answer to: What type of new charging port I need to buy?the port breaks because they cut half of it out to fit the case, you can get it swapped out by a phone repair shop for a regular micro usb port and file away a bit of the case to suit. and alternative if you do not use otg is to take it apart and introduce a charger direct to the battery, if desperate then soldering a regular usb cable to the battery points and using an intelligent charger to prevent overcharging, the better way is to take a case such as the fintie slate 7 one and stitch a QI charging circuit into the case then put a QI 1000mA receiver pad onto the back of the note 7 case underneath the copper sheilding and solder to the battery. with a steady hand you can route the +5v through the original charge circuit but its less hassle and easier to go straight to the battery. the chager will tell you when it is working and switch off when the device is full. cost - around the same as getting the original port replaced but less risky IMO.
