For my son, the device works great. But if you wanted it to be more marketable to a wider age range, having the ability to make and receive calls and save voice messages would open up the age range.
Without holding a degree in communications, programming, or networking I’ll try my best to illustrate what the device would be able to do:
-Have it’s own dedicated phone number
-On a PC or smartphone app you can change settings for each Relay device, block phone numbers, delete voice messages, set ringtones (for contacts, unknown numbers, and numbers not in contacts), set colors (for when a contact or a non-contact calls on silent mode), add contacts and edit the Relay’s device name.
-Call others by long pressing the center button twice, on the second press a chime prompts the user to speak a name on the contacts list or speak a phone number, then the device places the call
-Long hold the center button till a chime and your voice messages will play from a voice box.
-press the button once to end a call (Have a call work like a phone and not like a walkie talkie)
-Receive calls by hearing a ringtone and clicking the center button once to answer the call or if volume is down the center button lights will glow.
If you could implement this and still retain the 8$ monthly subscription I would ditch my smartphone and it’s carrier. Thanks for reading!
