Phone issue and complicated situation in my head

[Hanshua]

OK. Essentially my phone screen temporarily glitches. Where a line stretching half the screen would appear and then disappear milliseconds after. Phone is a s9 under warranty and i was wondering if it was worth it to get the screen fixed and out of action over a small tedious issue. 

Thanks.

Well if its under warranty then yes get it fixed that may be a dying gpu and could result in a unusable phone if the gpu fully dies
