What is true of this model and changes how you fix it

Model — Luxe (fashion tracker)
A slim, jewelry-style fitness tracker for heart rate, activity and sleep. NO built-in GPS (connected GPS via the phone), NO ECG, no microphone/speaker, no cellular — so those symptoms do not apply. Style-focused with a small color AMOLED touchscreen.
Connected GPS only
Relies on the phone's GPS for mapped workouts — carry the phone for distance/route accuracy.
Small touchscreen
Its small touch screen can feel fiddly and, like the Charge 5, unresponsive with wet fingers — a touch quirk, not necessarily a fault.
Water and screen
50 meters of water resistance, and a 0.76-inch AMOLED display at 124 x 206 pixels.
Build
33.5 x 17.5 x 10.1 mm with a surgical-grade stainless steel housing and silicone band with an anodized aluminum buckle.

Exact questions

Questions that only have an answer for the Fitbit Luxe

Does the Fitbit Luxe have GPS or ECG?+

No to both — the Luxe is a slim, style-focused tracker that leaves out built-in GPS (it uses your phone's GPS when carried) and has no ECG sensor. It tracks heart rate, steps, activity and sleep. So GPS distance needs your phone along, and there is no ECG, voice or cellular to troubleshoot — those features are on higher Fitbit models like the Charge and Sense.
