Hi @Smyrnaeverythin. First, is your touch-screen device a Square device (Register, Terminal) or is it an Android/Apple device? When you say “software version was updated 7/1” do you mean Square software or operating system software?
For now, a few general suggestions. Try rebooting the device. If that doesn’t work, you might need to factory reset it. If those two things don’t make any difference, then it sounds like you have a hardware issue of some kind, and it might need to be replaced. Hopefully, it is still under warranty, if that is the case.
FYI, electrical interference is pretty rare in a normal retail setting. These devices are designed to work around lots of other electronic devices without interfering with each other.
Anyway, after you answer those two questions, maybe I can give you a few more suggestions to troubleshoot.
