My Galaxy Tab 3 7.0 (Sprint) started to be unable to connect via Bluetooth to my Contactless Chip reader a couple weeks back. I tried all troubleshooting and even called into Square Support. They informed me there was a software compatiability issue and were working to update the Square app.
I was not deterred and continued to try and get it to work........and I DID!!!!!
My work around was to actually put my Contactless reader in pairing mode (i.e. 4 orange flashing lights) and then go into my Bluetooth control panel on my Tab 3. Once there, I hit "Scan" and it found the reader and I paired it manually. Viola!!!!! I'm now back biz!
