Q: QuestionWhat is the difference between unlocked and GPS(3 answers)
A: AnswerUnlocked is if you want it to have its own number with your phone company so you can use it independently of your phone. (You don't have to carry your phone everywhere). GPS uses Bluetooth to connect to your phone. Meaning certain functions won't work if you're away from your phone.Answered by BGD2
Q: Questionwhy does it say that it does do blood pressure if it does not?(1 answer)
A: AnswerIt can, it's just not authorized in the United States for obvious litigation reasons. It's fairly easy to add on this feature, with a little bit of research on YouTube. I use the feature all the time and it's acurate.Answered by MrBucket
- A: AnswerCustomizable. It is Android. Everything can be changed

Q: QuestionWhat is the difference between BT and LTE ?(2 answers)
A: AnswerThat is a great question! If the Galaxy Watch4 is Bluetooth, it means that your phone is required to be within range for full functionality. If the device say LTE, you are able to get services through your carrier to be able to leave your phone behind and still experience all of the features the watch has to offer. Thank you for taking the time out to reach out to us. ^KaylaAnswered by Samsung
- A: AnswerIf you are looking for a non-silicone band & like a little bling there are some great choices on Amazon that match this watch exactly. I had purchased 2 bands for my Active 2 pink-gold watch that didn't quite match but it was close. The back came off that watch & Samsung wasn't able to repair it so I got this one, I was so surprised & happy to see that the bands match this one exactly! I always get so many compliments, it makes it an even more beautiful watch! You can find many that don't look cheap or gaudy & have very subtle bling, & there may even be some w/o the bling but that's what I was looking for. This isn't my favorite one but it gives you a good idea of the color match.

This is the one!!
Didnt think I would like this as I dont wear watches normally. Working out recently has made me want to try one in order to track steps and such. That being said, I took a chance and guys this watch is amazing. I dont care that it is couple generations old. Still feels premium. Super comfy. The 40mm is perfect for me as I have quite small wrists for a guy. It looks great and functions wonderfully. Looking for a cheaper smart watch but wanting to stay in the Samsung environment? This is the watch! Get it!

Awesome upgrade
While i miss my original Samsung galaxy watch, this one is a awesome replacement. Its sleeker and the hidden strap is genius, the old strap used to slip and catch on things when i was busy and now i no longer have that problem. It also has a longer battery life than my old one. And i enjoy the ability to customize the watch face for exactly what i need to see and use most often on the watch.

Love but battery doesn't last as long a year later
I love this watch. I wear it everyday. It's very accurate with my workouts. Ive had it a little over a year now and the batter is starting to not last as long. This happened with my last samsung as well. With the gerk squad warranty it was replaced and i will have to fo the same woth this watch also. I dont have a ton of stuff on the watch and its not really beijg used all day. Just worn all day. Its going dead by 6pm and I'm charging it wvey night. Everything else about it I love and will continue to always use a samsung smart watch.
