Hey there, @Ledo31! Thanks for joining us. 
I see... Well, that definitely doesn't sound like normal behavior. Let's go ahead and find a solution for it! Just out of curiosity, have you tried restarting your Surge? If you haven't already I suggest doing the following at least three times:
- Press and hold the Home and Select buttons (left and bottom right) on your Fitbit Surge for 10 to 15 seconds, until you see the screen flash or start to dim.
- Let go of the buttons.
- After your screen turns completely off, wait 10 seconds and press the Home button to turn your Surge back on.
Charge your Surge using the following tips (How do I charge my tracker?) and then test your tracker. If it doesn't work, then the best course of action would be to contact our Support Team. They definitely have the proper tools to take a deeper look into your tracker's behavior. Mention them all the troubleshooting steps you've done to fix this. By doing that you'll be helping them to provide you with a quick follow up!
Good luck and keep me posted with the outcome!

@Ledo31 thanks for the update! I'm a little confused here. So if I understood correctly (please correct me if I'm wrong), you're trying to set up your tracker from your mobile device's Bluetooth settings? If that's the case, you need to pair it directly to the Fitbit app first. Pairing your Surge to your mobile device's Bluetooth settings is for it to work with the Call/Text Notifications plus the Music Control. I'm curious as to what happens when you open your Fitbit app and attempt to sync your tracker? Make sure that your Bluetooth is always on when trying to sync.
If you give me a chance I can walk you through the set up and syncing process and I highly appreciate you're taking the time to troubleshoot your tracker with me here in the forums. I understand it could be frustrating at times but when we get it to work, we'll both feel relieved and happy to have it working again. I don't want to get off topic but would like to share with you my personal experience with my Surge. It goes like this: I once noticed that my Surge worked great with Call Notifications but it wasn't working with my Text Notifications. I went through the troubleshooting steps like twice or three times until it worked. It was frustrating in the beginning and it made me feel like I was doing something wrong. However, I didn't give up and finally got it working. 
It has worked great ever since.
Please let me know which mobile device you have so that I can post the proper troubleshooting steps. Let's give it a try one more time!
Now on a different note, I see you mentioned you have purchased your tracker 6 months ago. A refund is no longer possible as you have 45 days from the date of purchase to request a full refund if you are unsatisfied with your purchase from Fitbit.com for any reason. Now, if you purchase from a different retailer, you'll have to follow their returns and refunds policies and please note that we're unable to influence their policies. However, since your tracker is covered by 1 year warranty, you can contact our Support Team for a deeper analysis of the issues your tracker is experiencing; so if they deem that your tracker isn't properly functioning, they shall evaluate if a replacement falls in place. Here's Fitbit's Warranty Policy so you can review it.
I'll be looking forward to your new comments!
