Samsung ZFLIP4 - Black screen post 6.1.1

[Obsydian]

My wifes mobile started with this issue, screen is immaculate as is the mobile, but randomly goes off, front and inner screen just black/blank, cannot figure out if it is loosing power of a screen issue or something else.

Not got it to hand at the moment, but has anyone experienced such an issue

Have came across other posts with similar issues. Something you could try when it does this.
Force Restart: If a soft restart doesn't work, try a force restart by holding down the power and volume up buttons simultaneously for about 10 seconds. This will force the device to power off and on, potentially fixing any software issues that might be causing the screen to malfunction.

Will try later, but just had a message "As every time i close it goes off", she can then press and hold the power button to restart.

Will try when she is home, worst case a factory reset, did the usual Cache wipe after 6.1.1 was fine, but this to me is the same as my ZFOLD3 and ZFOLD4, whereby the front screen just going blank when closing or opening. I am 100% its more the ribbon cable connector, but both repairs said nothing about what was actually repaired.

I did read someone on reddit. Theirs was a ribbon cable and got it repaired under warranty.

Yeah just had a quick look, allot of people having the issue across Flip 4, 5 and 6, all after 6.1.1, odd.

Got to be software issue. Remember to send error in members also 👍

Spent yesterday backing up and trying to fix the ZFLIP4, from Samsung Communities, Reddit, YouTube and XDA, The conclusion it cannot be a hardware issue it is software-related, given numerous users (Flip/Fold 3,4,5, 6) and I in the past returned devices for repair to either be told no fault found or something replaced, returned and the issue still persists.

Some guy mentions it is the closing magnets ???, trying to find if anyone has managed to roll back to the prior firmware and see if that helps.

Question - how to fix random black screen after opening phone | Page 3 | XDA Forums

I'm not sure if it is possible to roll back to the previous software. Either way I hope the issue gets resolved for you real soon.

My wife's phone has the same issue. Screen flickers on and off. It goes blank when you close it. You can get it back sometimes by tapping on the screen or using soft reset. It's the connector on the back of the screen. Id be careful because it can cause stuck pixels. Which if you choose to get it fixed under warranty will lead to an 'Out of Warranty' repair as Samsung regard stuck pixels as cosmetic damage. In the end I pursued the retailer and got compensation. All credit to them, I might add.

Am certain its software, there are too many incidents across the GEN 3 to 6 Flip and Folds coincident with a big OS update, plus my repair and others either found no fault or were non-screen related.

Forgot to say speaking of compensation I need to find an update a post about taking my Music Server company to court, 1.4 years later I was in court this morning, great news is the Judge ruled the manufacturer bricked my device they are liable and kicked out loads of nonsense arguments.

It's not over, as Judge said to the Defendant agreed to pay up or goto a half-day trial, all over £342, their legal fees are circa £10k, and the Judge was pissed.

The bottom line its is hard, worrying and stressful.
