I have downloaded the square app, and plug inm my card reader, but the card reader won't read a card. The app is working otherwise and on key in cards. What is the problem. My phone is samsung galaxie prime core, verison.

Hmm, that device should work fine with the reader, @thaloblueartist. Have you had a chance to try out these tips? Let me know!

I just signed up for Square. I have a LG G5 phone. Is that compatible for the basic Square device?

Hi @winwithrose, it should. While it may not be on our Compatibility List, that may be because we don't have enough data on the device at this time to make an official comment.

Given that it is a newer model, it should meet our technical requirements. I just can't promise it!

Hi Sean, hope you can answer my question about compatibility! 

I am considering either the LG X Power or the Samsung Galaxy Amp Prime. These phones are from Cricket. Are they compatible with Square?

If they're not compatible, can you recommend a budget-priced 16 gig Android 6.0+ phone with a budget-priced cell provider? 

Thanks! 

Have a similar issue.  I have a new Insignia 8" tablet from Best Buy running 6.0.1 Android.  No Insignia tablets appear on the Square Device Compatability page.  The Square app loaded from Google Play without issue.  Successfully used the Swipe to run a test with a VISA.  The Android setting page indicates there is a Bluetooth device available to pair when the Contactless Reader is on (displays as 6 pairs of alpha numerics seperated by colons).  (The device goes away when it is off.)  With the reader displaying 4 blinking orange lights and working fromthe Square Menu; Settings; Card Readers; Contactless + Chip; --> I then get a generic Square page with an intro video and two buttons allowing me to order a reader or Check Device Compatability.  Dead end!  What should I do?

Hello,  

Is Samsung Galaxy Stardust compatible?

Need help finding a good phone that is compatable with this square.. any help appreciated.

Search here for compatible devices:  https://squareup.com/compatibility  Square is only compatible with select Apple and Android devices, but the list is quite long.

I have a Galaxy Note 5 and I see all other notes on the list, but not mine....?

Hey @Candifer1, you can view which hardware is compatible with your Galaxy Note 5 at squareup.com/compatibility. Take a look at @Sean's post above for more information as well. Hope this helps!

I have a Motorola Droid Turbo 2.  with 6.0 Android software. So why doesn't my wireless card reader pair up?

Considering a

BLU R1 HD and want to know if it will work with Square?

@windhorse - It doesn't look like we explicitly support this device. While it looks like it would meet our basic requirements, you'd have to test it out to know for sure. 

@mtf Check out the information in this thread. It should help point you in the right direction.
