Galaxy Z Flip 4 display crease: signs of damage

A Galaxy Z Flip 4 display crease is often where a faulty folding screen first shows itself: a line, a black bar, flickering or a touchscreen that no longer reacts. If the phone also does not close cleanly, we also check the hinge and the housing, because the cause is not always the screen alone.

Galaxy Z Flip 4 screen replacement

When there is damage in the crease, the main display usually has to be replaced. On the Galaxy Z Flip 4, the screen moves every time the phone is opened and closed. If the display layer breaks, a flex cable is affected or the hinge puts pressure on the screen, it shows quite quickly. Pressing hard on the screen or repeatedly opening and closing it “to test it” is not a good idea at that point, because the damage can get worse.

On the repair page, we show the current price for a Galaxy Z Flip 4 screen replacement: 359 CHF. If we do it together with another repair, this item costs 259 CHF.

Line on the crease

A line on the crease of the Galaxy Z Flip 4 usually points to damage in the panel itself or in a layer under the screen. It can start as a fine line; if it grows, changes colour or reacts when the phone is folded, we treat it as screen damage.

Black bar on the display

A black bar on the Galaxy Z Flip 4 display usually means that part of the screen is no longer working. If the bar sits exactly on the crease, a screen replacement is very likely.

Display flickers

If the Galaxy Z Flip 4 display flickers, the cause can be the panel, the flex cable or pressure around the hinge area. If the flickering changes when the phone is opened, it is better not to keep stressing it and to have it diagnosed.

Touch no longer reacts

If touch no longer reacts on the Galaxy Z Flip 4, the whole screen can be affected or only the area around the crease. If the image still works, make a backup straight away if the phone still allows it.

Galaxy Z Flip 4 hinge fault

A faulty hinge on the Galaxy Z Flip 4 can press on the screen from the inside or change the folding path. Then the line in the crease is not the only sign. We look at whether both halves move evenly, whether the housing sits proud and whether the screen is being pushed upwards around the fold.

Phone does not close properly

If the Galaxy Z Flip 4 does not close properly, do not force it shut. The cause can be dirt, a bent housing or a damaged hinge; extra pressure can damage the display.

Galaxy Z Flip 4 diagnosis

With foldable phones, a quick diagnosis makes sense because similar symptoms can come from the display, the hinge or housing parts. We check how it behaves when opening and closing, the touch response, the image at the crease and whether the phone folds without resistance and without running crooked.

Customers from all over Switzerland can send the phone in by post. We send a box free of charge and pay shipping both ways as a tracked A+ letter. Transport insurance can be added up to five hundred, one thousand five hundred or five thousand CHF. If you do not want to go to the post office, you can have the parcel collected from your door for 10 CHF. A repair by post usually takes two to three days until the phone is back with you.

If you found the same repair cheaper somewhere else, you can send it to us — we will make you a counter-offer. Describe the symptoms and book the Galaxy Z Flip 4 repair, then we will check whether it is the screen, the hinge or another part.
