I’ve got a Samsung 10.1 tab3 and it’s not turning on – when I unplug the battery and plug it back it, I get warning saying “Low Battery Must have higher than 3.4v”- Are you guys able to fix this?
Have you tried a different charger/Cable or anything like that? If not i suggest trying this first, and seeing if this makes any difference.
If that still doesnt work, you could either have a faulty battery or possibly a faulty battery. Then i would suggest following the link below and selecting the ‘Diagnostic’ option on the drop down menu. (It shows the 8″ version, but this option covers both)
