Screen Jumping/flickering

[Furree]

Hi,

I've had my Xperia Z3 for a few months and everything has been good. Over the past couple of weeks however, my screen has been jumping. It sometimes looked like it was scrolling by itself or getting stuck and stuttering like someone is scrolling up Abe down really fast. This was only happening in the Facebook app but now it's happening on YouTube, Photos and even my own home screen. (flickers from bottom upwards).

Problem persisted after latest software update and is also happening during Safe Mode. But whenever I record the screen or take a screenshot, the jumping or flickering does not show up. Phone hasn't been anywhere near water and hasn't been dropped.

I did have a screen protector which I thought might be causing these issues but the jumping and flickering continued after I removed it.

Also, my phone screen goes black when I make a call and I'm unable to make it light up until the person on the other end hangs up. This renders me unable to use the dial pad or just access my phone whilst on a phone call. I figured out that pressing my thumb on the proximity sensor lights up the screen again, and that perhaps my screen protector was messing with it, but the problem persists even when I removed my screen protector.

I would really appreciate any advice on these issues. Thanks for reading!

repair the phone with Sony PC Companion, if that doesn't solve the problem contact your local Sony xperia support.

Did you repaired your phone ? Update please ?

I repaired it with Sony pc companion but the problem isn't going away, in fact the flickering has gotten worse. Gonna hand in my phone, still have the warranty so hopefully that should fix it.

I think it's a stagefright

[Furree]

What should I dooooo

[thomasacquins]

Use a good antivirus software

[thomasacquins]

Every android phone is under stagefright threat. When a device is affected by stagefright it became unstable. The phone restarts itself. Softwares will force close .My old Xperia phones Xperia L and Xperia M.

Both phone was vulnerable to stagefright and became unstable.

That's awful. I was gonna give my phone in today... I have an anti-virus already but clearly it's not done much if the phone is really affected by stagefright 😐

Good decision give it to Sonymobile service. They will fix it.
