Why doesn't my screen react?

It sounds like your Samsung Galaxy Watch Active2 is experiencing touch responsiveness issues. Here are some steps and considerations to diagnose and potentially fix the problem:

1. Steps to Diagnose Touch Screen Issues:

1. **Clean the Screen:**

- Sometimes, screen responsiveness issues can be caused by dirt, oil, or debris on the screen. Clean the screen with a soft, lint-free cloth.

2. **Restart Your Watch:**

- Restarting the watch can often resolve temporary software glitches.

- Press and hold the Home button until the Power Off screen appears. Tap on Power off, and then restart your watch.

3. **Update Software:**

- Make sure your watch is running the latest software version.

- Open the Galaxy Wearable app on your connected smartphone, go to Home > About watch > Software update, and tap Download and install.

4. **Check for Rogue Apps:**

- Sometimes, third-party apps can cause touch screen issues. Try booting your watch in Safe mode to see if a specific app is causing the problem:

1. Press and hold the Home button until the Reboot screen appears.

2. Touch and hold Power off until it changes to Safe mode, and then tap Safe mode.

3. To exit Safe mode, restart your watch as normal.

5. **Perform a Factory Reset:**

- If the issue persists, performing a factory reset may help:

1. Open the Galaxy Wearable app on your smartphone.

2. Go to Home > About watch > Reset watch.

3. Follow the on-screen instructions to reset your watch.

- **Note:** A factory reset will erase all data on your watch, so be sure to back up any important information beforehand.

6. **Check for Physical Damage:**

- Inspect the watch screen for any cracks or physical damage. Physical damage can interfere with touch sensitivity and may require screen replacement.

7. **Contact Samsung Support:**

- If none of the above steps resolve the issue, it's possible that there's a hardware problem with the touch screen.

- Contact Samsung support or visit an authorized service center for further assistance. They can diagnose the issue and advise on repair options, which may include screen replacement if necessary.

1. Additional Tips:

- **Use Touch Screen Sensitivity Setting:**

- In the Galaxy Wearable app, go to Advanced > Touch sensitivity and adjust the setting if available.

- **Avoid Screen Protectors or Covers:**

- If you're using a screen protector or cover, try removing it to see if it affects touch sensitivity.

By following these steps, you should be able to diagnose and resolve the touch screen issues on your Samsung Galaxy Watch Active2. If the problem persists, professional repair may be necessary.
