My Ring 2 won't work anymore

Wed, 10 Jun 2026 22:04:35 +0000

I just got the Ring 2 a couple of days ago. I charged it over the last day and am trying it out for the first time. I paired it with my Samsung S26 Ultra but couldn't get the function to work, as expected. I installed the Ctrl4U app and updated firmware to v42. When I went back in the app it stated that there is a newer version v43? (at least for the camera control portion). It started the update and hung during the update. Now the ring won't work at all - no lights on the ring no matter what action I take - press the tactile button rapidly as well as holding it down for a long time. Nothing at all. No lights and the app doesn't show the ring as connected to it. I tried putting on the charger but still no luck. Is there a hard reset/reboot? What are next steps?

My Ring2 won't start and won't charge anymore.

I haven't charged my Ring 2 for a week, hoping it would completely discharge so I could restart it after charging it yesterday. However, it hasn't charged and won't turn on. I hope support will get in touch and offer a solution.

Answered: Ring became unresponsive in middle of updating

Wed, 08 Apr 2026 04:35:18 +0000

Hi, normally the fail is caused by Bluetooth re-connection fail before upgrade.

Please try:

1. delete your device from APK by drag it towards LEFT

2.research device by pressing + on top right

3. if device can be found again, please continue sw upgrade.

If above does not work, you have to wait for battery used up, and then recharge it.

The bluetooth re-connection fail is a bug from Bluetooth firmware which is coming from Bluetooth chipset vendor.

Answered: If the Ring responds slowly or non-responsively during use or the wearing function fails, etc

Answered: Is the Ring II an all-around upgrade to the ring I?

Thu, 26 Feb 2026 02:29:53 +0000

Ring II has no mouse function, it more focus on supporting action camera .

But we are continuously improving Ring Control(not Ring I)mouse performance. we will have new Firmware 42 in Mid-March. And will discuss internally if scrolling speed option can be added in Firmware 42.

Thanks for your suggestion!

Answered: Where can we buy the new "Ring 2"? Is it even commercialised at the moment?

Hi, order can be placed now before mid-March on below Kickstarter link. We will start to sell in Amazon from April.

Answered: It does not seem to be sensitive enough when sliding with fingertips

Tue, 04 Mar 2025 01:25:23 +0000

The touch module is light sensing, not pressure or capacitive sensing. The working area is 1mmx1mm in the center, and the fingers should completely cover the center of the circle when swiping.

Answered: The current content cannot be swiped in navigation mode.

Tue, 04 Mar 2025 01:24:18 +0000

It may be because the cursor is not in the current position. You can press the TS key to switch the cursor position and try again. For example, when browsing the comments section on TikTok with an Apple phone, the cursor may not be in the comments section, and you need to press the TS key to switch to the comments section.

Answered: If you cannot swipe in iOS navigation mode during use
