Ubrokeifixit Galaxy Watch 46mm R800 R805 Rear Back Lens Glass Sensor FPCB/FPC Flex Cable Replacement for Samsung Galaxy Watch 46mm SM-R800 SM-R805(NOT for 42mm)-46mm

Just leaving a review to confirm that it is indeed a legit heart rate sensor. My Galaxy Watch 46mm did not live up to a few hours on the river and seemed to have died. I resurrected it by cleaning it, but the heart rate monitor did not last. I won't lie, this didn't fix it and it's still broken, but there's obvious corrosion inside my watch and I highly doubted that replacing the sensor would fix it. 5 stars because it may work for others!

I orderd this Back Lens Sensor Flex Cabel Replacment for my Samsung Galaxy watch 1 it has bin dead for months finally decided to order parts to fix it, this ribbon has the lights that flash under the watch that detect your pulse for various functions easy to install if you have the tools and patient, it did not come with the tools! it has a blue plastic tab in the middle covering the adhesion to hold it, in place on the inside of the back cover, make sure you peel it off and apply slight pressure when installing, be carfull not to apply to much pressure becouse on the opisit side of the back covers center, you have a small glass for the pulse sensors to see your wrist, I had to replace the back cover becouse mine had a broken glass Good part worked well grate price!

I used this to fix my Galaxy Watch's heartrate sensor. It worked well and was the only choice now that the watch was out of warranty.

Easy to install but it did not work.

Worked I suppose. Watch may have been too far gone to save.

Muy buen producto, mi reloj se estaba descargando demasiado rápido y los leds del sensor no se encendía, luego de reemplazarlo el reloj volvió a la normalidad. Al parecer el sensor se dañó por el ingreso de agua.

no me gusto ya que solo encienden los led pero realmente no funciona como sensor, las funciones del reloj no se activan

It was very easy to install and dixed my problem
