Thanks for taking the time to leave a great 5-star review of your Galaxy Watch8, Christina. We're elated that you are happy with the look of the watch and the display and other features! With the wireless charging pad, the watch is not designed to be used with this pad; this is why the curved strap will not lie flat against the wireless charging pad, but you could remove the straps to achieve this. However, we will pass on this feedback for future developments with the watch series. KF at Samsung Support

Thank you for taking the time to share your thoughts on the Galaxy Watch8, Carlie. Your feedback is really important to us, as it helps us to better meet your needs. Battery drain can be caused by high screen brightness, unused trackers, background apps continuously running, apps running on old software, continuous GPS use, and an Always On Display. The following link contains more information and also remedies for this: https://www.samsung.com/uk/support/mobile-devices/reduced-battery-life-on-your-samsung-galaxy-watch/ For the low vibration, we'd recommend firstly checking for software updates. You can update your Watch8 either directly from the smartwatch or through your connected mobile device using the Galaxy Wearable app. To update on your connected device, go to the Galaxy Wearable app > Watch settings > Watch software update > Tap Download and install. To update on the watch itself, go to Settings > Software update > Tap Download and install. The following link from our Canadian colleagues contains more helpful steps that you can carry out to resolve the issue: https://www.samsung.com/ca/support/mobile-devices/samsung-smartwatch-manage-sound-and-vibration/ We're really glad to hear that you're enjoying all the other fantastic features of your smartwatch, and we hope this information is helpful to you. ^EW at Samsung Support

The LTE function of the Galaxy Watch8 allows it to work independently without being connected to a phone, as it connects to the network via an eSIM, Jim. Some functions of the Galaxy Watch8 do work seamless with the Samsung Health App, which is an application that you'll find on a Samsung phone. Our returns' policy does clearly set out the terms and condition for any return, and we do ask you to follow these terms for more information on any applicable charges: https://www.samsung.com/uk/shop-faq/returns-and-cancellations/what-is-the-returns-period/ ^JM at Samsung Support

We love to hear that you’ve been enjoying a good experience with your Galaxy Watch8, especially thanks to its long-lasting battery and brilliant health tracking features! We also appreciate you letting us know that the network connection can be inconsistent at times. There are a few quick steps that usually help improve network stability. Restarting the watch, checking that the mobile plan is fully activated in the Galaxy Wearable app and ensuring that the eSIM is showing as active on the watch itself can often restore a strong connection. It can also help to toggle Airplane mode, refresh the mobile network settings or try the watch in a different location in case the signal is weaker in your area. If the issue continues, we recommend resetting the network settings on the watch or contacting your mobile carrier to confirm that the eSIM is working correctly. Our support team is also here to help with any further checks.
