Hi! I see that you’re experiencing black lines on half of your HryFine screen. To help you better, could you please tell me a bit more?

- Is this a smartwatch screen issue or another device?
- Are the black lines horizontal, vertical, or something else?
- Did the lines start appearing suddenly after a specific event like a drop, update, or charging?
- Have you tried any fixes yet—like restarting the device or adjusting display settings?

Once I have these details, I can guide you through some steps to address the problem. Looking forward to your response!

this is smartwatch ,horizontal lines appear, yes lines appear after charging,yes i tried to fix it as to restart it

Thanks for the details! Since the horizontal black lines appear after charging and restarting hasn't helped, it might be related to either a loose internal connection between the display and the internal circuitry, or potentially a hardware fault with the screen itself.

Here’s what I recommend trying next:

1. Check the Charging Cable and Port: Make sure the charger is aligned correctly with the watch’s charging contacts. A misalignment can cause unusual display behavior after charging.

2. Try Charging with Another Adapter or Cable (if available): Sometimes power fluctuations can affect the display.

3. Perform a More Complete Reset: Some HryFine smartwatches have a forced reboot or hardware reset option — for example, pressing and holding both buttons simultaneously for about 10-15 seconds. This can sometimes clear deeper software glitches that restart alone won’t fix. If that’s something you haven’t tried yet, it’s worth attempting.

4. Inspect for Physical Damage: Although you didn’t mention drops, double-check that the screen shows no cracks or pressure damage.

If these steps don’t resolve the lines appearing post charge, it might be a sign of a faulty display connector or hardware defect. From user reports on similar issues, the connector between the OLED screen and the system on chip (SoC) can be problematic2. A technician can fix this, sometimes by reseating the wire inside.

If your watch is still under warranty, I recommend contacting HryFine support or the seller for a repair or replacement option — they might have your device covered.

Would you like me to walk you through the forced reboot step or guide you on how to contact support?

What causes horizontal lines on smartwatch screens?

Great question! Horizontal lines on smartwatch screens like your HryFine can be caused by a few main factors:

1. Hardware Issues: This is often due to a loose or faulty connection between the watch’s screen (often OLED) and its processor. Sometimes the internal cable or connector can become loose or damaged, especially if the watch has undergone physical stress or even after charging if the contacts aren't aligned well. This can cause persistent lines on part of the screen.1

2. Physical Damage: Cracks or pressure on the screen can cause pixels to malfunction, resulting in horizontal lines or flickering. Even if you don't notice obvious cracks, internal damage from drops or impacts can affect the display.

3. Software Glitches: Sometimes software errors or bugs can cause display artifacts like lines. In those cases, restarting the device or updating the software can often fix it.

4. Watch Face or App Issues: Certain watch faces or apps might not fully comply with the device’s display guidelines, causing lines to appear, particularly in Always-On Display mode. Uninstalling third-party faces or apps can help.2

5. Water or Moisture Exposure: If moisture has entered the device, it can short circuitry or damage display components leading to lines or flickering.

Since your lines appear after charging and restarting didn’t help, it leans more toward a hardware issue or a faulty connector inside the watch screen assembly. Checking for software updates and removing custom watch faces might help rule out software causes.

If you want, I can guide you through verifying if a software update is pending or walk you through uninstalling any custom watch faces to test. Otherwise, a repair might be necessary if hardware is the root cause. How would you like to proceed?
