HQB-STAR 2 Pcs Galaxy Watch Active 2 R830 R835 Back Glass Rear Lens Glass Replacement for Samsung Galaxy Watch Active 2(40mm.44mm) and Galaxy Watch3(41mm.45mm) +Tools

This product worked great . My 14 year old repaired watch back independently.

Firstly the transparent square plastic was missing. That made installation of adhesive ring a nightmare. There are other on Amazon which are far better. Secondly, the adhesive right is not sticky enough, could not hold the back even for half a day. Total disaapointment.

Used this and now my heart rate and sleep, etc detection doesn't work.. hopefully can undo what I did.. that's the galaxy watch active 2

I bought a refurbished Samsung Galaxy Active 2 watch (40mm) and after 6 months, the back was falling off due to failing adhesive. So, this set was just what I needed!This set comes with all of the basics for replacing the back of your Samsung Galaxy Watch. You have all you need to get started - wipes, Exacto blade, plastic blade, extra adhesive rings and 2 backs. BUT, it did not include instructions which can lead to user error. There are tutorials online, but I chose to try this without researching. *I would suggest tweezers to help keep oils away from the delicate adhesives.*What worked for me (with pictures):0. Thoroughly clean your watch back using the wipes and knives - no old adhesive or oils around the inner ring. Q-tips and alcohol help. Be gentle around the laser components.1. I peeled the adhesive backed red disk off the transfer sheet.2. I used the Exacto blade to gently remove the paper backing (it started separating, so I moved to another spot).3. I applied the exposed adhesive to the back of the replacement part (still on the transfer sheet) and used the plastic knife to press it down and ensure it had full contact with the surface.4. I used tweezers to peel the transfer sheet off of the back of the adhesive, go "low and slow" so it doesn't peel off the adhesive.5. I used the plastic sheet to help align the disk with the back of my watch, look for the two plastic pins near the laser and ensure the backer lens does not sit them. (Do not tough anything with your fingers).6. Press firmly, apply weight and let sit for 6+ hours (like a command strip). It will need time to adhere.After that, it should be good! I wear mine 24/7 and have not had an issue after 2 days. I will update if it ends up failing. Note: I do not trust this submerged in water (yet) as other reviewers mentioned failing adhesive.Happy Repairing!

It coems as expected, was a little more expensive than competitors but comes with 2 back plates, adhesive etc.No install guide or information.They don't make it easy to install.Adhesive doesn't work and it twists...
