A8 Tablet Display Screen Lines

[sopharb]

Hi all,

I got my a8 tablet just 2 days ago, I've gone to use it today and lines have started appearing on the screen, I've restarted and they slowly fade in where it says samsung on start up and then whenever I click on something else they start to fade in whenever the display changes! It was completely fine when I have been using the past 2 days with no issues and haven't dropped it at all. I've tried restarting and doing a factory reset and its still happening! Anyone have any ideas or do I need to take it in for someone to look at?

Thanks!

Did you buy the device from New or used/ reconditioned?
If you go into the phone dialer, and the dial *#0*#
At the top are 3 different coloured test cards.
If the lines dissappear on those test cards. Its likely you have an app or theme that's causing this.

If the lines stay there on the test cards, then it's likely the screen has been damaged and this will need to be repaired.
Contact Samsung Customer Support and they can arrange this
If you bought used/ reconditioned. Probably best with looking at returning it to the seller

You should have if bought new, some recourse to return or exchange it. But this depends on where and how you purchased it

Hi, That number doesn't do anything on the tablet, the number just disappears but nothing pops up?

I bought it brand new through Vodafone. The lines change depending on what's on the screen, they're not permanent, it's so strange!

[Glenntech]

Strange that's not working. You are going into the phone app?
Like you are going to make a phone call

Give trying booting the Tab up in Safe Mode

Again if lines dissappear, then definitely something Installed that's doing this.
If you are gettingno where, then probably best to get in touch with Vodafone and get them to exchange it, or look at it.

Return it to Vodaphone then ?

[sopharb]

Yep, the number just disappears before I can even tap the call button with no pop ups. I've tried a full factory reset and opening in safe mode and the lines are still there!

I think I'll have to take it in for someone to look at as it seems like a hardware issue I think. Thanks for your help though!

[sopharb]

...what a helpful suggestion. thanks.

Hi there, @sopharb, and thanks for reaching out to the Community about this. Please can you let me know whether the following Hardware Test helps?:

1. From the phone dialler (Contacts app), please 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?

[Glenntech]

Yeah it sounds like a hardware problem.
I'd definitely return it especially as it's only a couple of days you've had it.
Just unfortunate this has happened for you

This is a hardware fault with the graphics chip..return it to the store
