Hello everyone!

I'm totally new to windows phones. Recetly (a mouth ago) I bought a Microsoft Lumia 435 Dual sim smartphone but I think the display itself is faulty. As shown on the pictures below, a vertical black line appers after about 20 mins of usage. First, a white dot (perfectly in the middle & the button of the screen) appers and after a few mins one more white dot appers but this time on the top of the screen (still middle). After that, few mins again the two dots get connected and form a black vertical line. Then I lock and unlock the phone and the black line gets wider and looks like a zipper (lol). The phone started doing this about a week ago. Why I think it is a hardware problem? Because I took screenshots and the line was not visible. After all if I reboot the phone the line disappers (o.O). Very strange. I downloaded the "Diagnostic Toolset" to check the screen with clear background.

If anyone knows a solution please tell me!
Thank you in advance!

I would definitely take that in for warranty repair.

Yes, that was my first thought also. But I'm hoping that there's a soluiton which can be done at home.

Sadly, that looks like a hardware fault. I had a 532 for about a day and the same thing happened. :(

Sorry, but not likely unless you want to go buy parts and try your hand at DIY surgery.

These things happen unfortunately.
