Hi,
I have a bright white line at the bottom of my screen, right below the keyboard. It appeared yesterday. What should I do? I restarted my phone but the line appeared as soon as thr phone restarted.

@cookiecat90 Please run a service test on your device by doing the following:

1. From the phone dialler, enter *#0*#.
2. Select RED, and then tap the screen.
3. Select GREEN, and then tap the screen.
4. Select BLUE, and then tap the screen.
5. Select BLACK, and then tap the screen.

While displaying the colours, was the issue still occurring?

It's a hardware issue then. Get your phone replaced if still in warranty

The next step is a master reset. Most software problems are cleared by doing a master reset

If your problem isn't solved by a reset, your device may need to be sent for repair. You may not want to reset your device because it is time-consuming, but it will happen anyway as part of the repair process due to data protection.

Please ensure any content you want to keep is backed up before you send your device to us as it will be wiped as part of the process. This includes messages sent using third party messaging apps, such as WhatsApp. Please refer to the app's settings for support on backing up messages.

Would you like help backing up your data?

Aaron, just for information is your master Reset a Factory Reset as we know it. CookieCat, I hope it gets fixed soon. I sent my Phone for repair using samsung service and it was back in just over a week looking brand new. They pick up and drop off.
