Samsung Galaxy Z Flip 4: Sub screen not working while upper speaker connected. Flip 4

Wed, 18 Jun 2025 14:02:33 -0700

Hi. I need some help. Few days back I have changed screen with frames (its because of broken hing after fall) also changed both baterries because old was already convex and I could not mount back covers :D

From the old frame I have took upper magnet (hall ic i guess) and mount it into the new frame. After this phone starts normally, both screen working fine but only problem is that its not turning on/off after I close it.

So my flip 4 when folded is not turning black main screen and back screen is not working (it seems like hall ic not working). In the test menu (*#0*#) when testing hall ic it also seems not working when folded, but when I put some metal staff on the front screen it says working pass, when i take it away it says realese pass. The same way i can turn main screen off and activate back screen, but still when folded its not working.

Now, most interesting thing - if I dont connect upper black cover with speaker connection its folding just fine. When I fold it its turning black and back screen works, when I open it its turning main screen on.

Now the question is - whats wrong with this plastic speaker cover that is preventing flip to works with hall sensor when connected, or maybe problem is somewhere else? But why its working fine without this upper speaker connected. I'm adding photos to let you know what plastic cover I'm talking about. Thanks!

Samsung Galaxy Z Flip 4: Phone not able to hold charge

Tue, 10 Sep 2024 15:48:13 -0700

Hi,

I have a Galaxy Z flip 4 that is displaying a strange behavior. When plugged to the power it works fine and it charges no problem.

When I unplug it it turns off and doesn't turn back on until I plug it back.

Now the interesting thing is that when it's turning on and I unplug the cable, it ends up turning back on and works fine until I fold it, then it turns back off.

I can't turn it back on unless I plug it back to the power.

I thought it was battery problem, I changed both batteries but still have same problem.

Any ideas?

Samsung Galaxy Z Flip 4: Front screen isnt working. Bottom half is darker than top.

Tue, 04 Jun 2024 14:31:58 -0700

Dropped my phone face first on the floor and the bottom half of screen is darker and can read my taps. The top half, however, doesn't register my taps and is brighter. when I call someone, my voice replays back in a warbled distorted static. the screen glitches out, and starts tapping on its own, and I'm forced to turn it off.

Samsung Galaxy Z Flip 4: Digitizer cracked and screen is black.

Fri, 15 May 2026 07:22:58 -0700

Phone was dropped (while closed) and when opened there was an audible snap sound in the hinge. Now the screen is black. I know the digitizer is broke and the cost to fix it. I just went and got a new phone but I want to get the pictures and other stuff from it. How can I do that without being able to use the screen? I've tried hooking it up to a computer but I need the touch screen to transfer.

Samsung Galaxy Z Flip 4: Black screen of death

Thu, 30 Nov 2023 16:25:28 -0700

Yesterday when I opened my phone I heard a "crack", and now more than half of the screen is completely unresponsive to touch and blacked out. I want to replace the screen myself since i'm pretty sure I'm not eligible for warranty. How should I go about doing that? Or is it better for this model to just take it to a repair shop? Thanks.
