Issue with Contactless+chip and Samsung S4

IBAGadget — Sun, 21 Sep 2025 12:26:08 GMT

Trying to get started with using Square and having a seriously frustrating issue trying to connect my Contactless + Chip reader to my phone. Spoke to Tech support when I had this issue yesterday and got my reader exchanged at the store I purchased it through, but still having the same issues. Chip Reader will pair with my phone, but then when it tries to connect I get the following error message:

Developer Options not Supported.

This device has enabled Developer Options. Please disable Developer Options in order to use Square's chip reader.

Problem is, Developer Options are turned off. I double check every time I get this message (every time I try to connect the two devices) and it is always turned off.

Reader finally managed to finish updating this morning, but that was after several failures to communicate between devices. For the tech savvy among you (I am not one unfortunately), Here are the specs on my phone:

Thank you for looking into this Tom. My current tablet won't support contactless, so I'm going to pick up a new tablet tonight and see if I can get it to work. If I can, then I can at least use it that way and keep my phone restricted to cc swipe.

Hey @IBAGadget, I'm so sorry for my delayed reply. Are you still encountering trouble with this? If so, please try a factory reset of your device. Once that's been done, please let me know if it helped—I'll relay to our Engineering Team.

Hi Tom. Yep, still getting the same error. Have reset the reader several times to no avail, and have even gone into my phone settings and cleared the data and cache to get rid of developer options, also with no affect.

Got it. Thanks for your reply—to be 100% on the same page, we'll need to make sure that you've done a factory reset on your Samsung S4. If you have any questions about that, I'd suggest calling our CS Team to review the steps for doing a master reset on your phone, or you may want to touch base with the retailer where you purchased it. Keep in mind that this may delete your personal data, so you may want to make sure that any important images, notes, or other files are backed up beforehand.
