I have several of these. They are perfect for my business, except they suddenly won't charge reliably. It isn't the port or anything like that, they're all doing the exact same thing. I plug it in, it first says 'slow charging' and recommends plugging in 'the charger that came with the tablet' Then, 10-30 seconds later, it pops up with the message that it isn't slow charging, it's actually not charging at all, and I can go ef myself. I've tried every single charger I have. I bought a new one. I have bought several. All LG or similar, none of my tablets will charge, they ALL do this. One is refurbed, the other is not, they should be up to date (I can't tell on one because it's dead now). I have googled and checked this forum, no one else seems to complain of the same. It's very frustrating, this is why I didn't by i-devices, the lack of universal charging. I've also tried plugging them into computers instead of the wall. NOTHING works. Now and then, the device will get 'fooled' into charging. Oh, and my car works, but charging tablets on gasoline isn't exactly my idea of a solution. But I can't keep going like this. Thanks in advance. A screenshot of the message assuring me my tablet won't charge at all is attached.
