ubrokeifixit Galaxy Watch Active2 Back Glass Rear Lens Glass Replacement for Samsung Galaxy Watch Active2 44mm,Galaxy Watch Active2 40mm,Galaxy Watch3 45mm,Galaxy Watch3 41mm (Active2/Back Glass)

Products works great! Also great price!No instructions which was a bummer. Looked up videos but none like this. All I did was remove the white strip (really hard to do without damaging it a litte bit so just becareful. I have long nails so that helped but try small tweezers) and attached that part to the back plate and removed the red plastic once attached. Then I attached to the watch (After cleaning any old glue and dirt). You can do the other way around whichever is easier.

The media could not be loaded. I created a step-by-step video on how to replace the back since there are no instructions. My last replacement lasted about 18 months of daily wear however I never wore it in the pool/hot tub. Considering the price of the watch and this is an actual Samsung replacement, i think the price is very reasonable especially if it lasts another 18 months.

Absolutely no directions. None. Waste of money.

As other reviews have mentioned, it does not come with any instructions. Plus, I didn't find a YouTube video showing how to install it as some other videos have mentioned. That's why I only gave 4 stars rather than 5. However, it's still fairly easy to install. I used lens cleaning wipes to finish cleaning the rest of the old adhesive from the rear of the watch before installing the ring tape.I haven't tried working out with it yet since I installed it today.Prior to the cover coming off, the ECG function was working. However, the ECG function no longer works. It looks like the window of the rear cover is a little hazy, which may be problem. I would have to remove the cover to clean it again, but then I would need new ring tape to reattach it. It would be great if the tape was sole separately...

Adhesive was not pre-attached to glass back, hard to get it aligned and then attach glass.

I'm on the 3rd time having to do this with my Samsung active 2. I've bought this kit every time. For some reason this 3rd time, both adhesives messed up. So it was a complete waste of money. I'm so annoyed.

Easy to install, fits perfect sensor works great. Great value, cheaper than taking it in to fix.

This product is not very well made. First, it doesn't come with any instructions what so ever. I went over to that video sharing site and found an appropriate video showing how to install the adhesive. There should be two distinct side to the adhesive, 1 for the glass sensor cover and 1 for adhere the sensor cover to the watch back. According to the video the red tab should expose one side that adheres to the sensor cover. I pulled the red tab and this pulled material from under the ring instead. I was forced to pull the clear backing off, stick it to the sensor cover and then use tweezers to remove the white ring so I could attach it to the watch. Would not recommend.
