Data transfer speeds via Lightning adapter is becoming less and less important—the last iTunes update removed iOS apps from iTunes. Apple is pushing more and more data transfers over wireless.
Both the iPhone 8 and Samsung’s latest (Note 8) utilize Qi’s Basic Power Profile (5 Watt), with the iPhone capable of receiving 5W, and the Note receiving 4.5W. The LG V30 utilizes the Extended Power Profile (15W) capable of receiving 10.5W. This pulled from the Wireless Power Consortium’s certified devices list (the LG V30 page: https://www.wirelesspowerconsortium.com/...) (the iPhone 8 page: https://www.wirelesspowerconsortium.com/...)
The iPhone 8 also supports fast charging—via Apple’s USB-C to Lightning cable (must be USB-C PD) and a compatible wall wart (like Apple’s 29W USB-C wall adapter).

It worked! Replaced the LCD to motherboard cable in Step 13; replaced the screen--100% functioning now.
I just received my replacement screen, and same issue is happening. Disconnected all of the cables to double-check, and found the mainboard to LCD cable has a partial tear where it doubles over. Just ordered a replacement on eBay; awaiting arrival. Will post results.
Board comes off with 4 screws (1 on the board, 1 on the metal tab covering a connection to the charging module, and the 2 holding the speaker on that side). Obviously disconnect all connections (I count 7 on the GT-N5100, not including those already disconnected for screen removal). The cable is just below the mainboard, and is held in place with a small amount of adhesive.
I'm having the same issue, and was told to try the following:
"1. Clean the digitizer flex cable with alcohol and carefully attempt to reattach the cables; make sure all cables and connections are secure.
2. There may be a "metal tape" on the original LCD Flex. Please remove it and put on the new assembly.This tape is for grounding purpose and without it, the LCD will not work correctly
3. Make sure your device is charged.
4. Do a soft reset of your device. "
About to try it on mine; if it still doesn't work it is either a damaged cable or defective replacement part.
