If you update your device's name using the instructions above, but it doesn't show immediately, turn your phone off and then back on again. Assuming you verified that the name change did go through using the methods above, this will fix the issue. Another reason your device's name may not appear correctly is that the sending device is already listed in your contacts. For example, if you're using a work phone and have that listed in the contacts on the receiving device, you may see the contact as 'work phone.'
