Flip 4 Screen not working properly after October Update

My wife received the October update on her Flip4 phone. Immediately afterwards it started to turn the screen off a little too soon (with a green flash) when closing, then upon re-opening takes half a minute to come back on.

Phone was working fine prior to the update and hasn't been dropped etc. Have tried wiping various caches (as per various forum post suggestions) but nothing helps.

Anyone else experiencing the same? Any ideas how to resolve? Thanks.

Hello @fwldavid and may I extend a Warm Welcome to the Samsung Community Forum 👋 

I'm sorry to learn your experiencing issues with this phone.  😔 

Do run the diagnostic tool found in your Samsung Members App to see if that highlights anything. 

You can also send feedback via your Samsung Members App. 

A Samsung Service Centre  / Samsung Experience Store maybe able to help. 

If i can be of any further help please don't hesitate to ask  😎

Hey, I have the same problem and my Members App did not uncover any problems. All tests pass ( especially proximity and sensors, which I was suspecting to cause the error).

When I unfold the Flip4, the back screen stays on as if the phone was closed and the main screen stays off. The phone obviously doesn't recognize it has been opened.

I can manually "enforce" the opening recognition by grabbing the upper half of the phone for a moment. I don't need to apply pressure, just grab it firmly for a second or two. I've attached a recording of the effect.

I performed the software update through Smart Switch. Maybe that is important information.

Do the hall or proximity sensors require some recalibration?

      I have the z flip 4 and mine is doing the same. Since the update the main inside screen is sometimes not coming back on until after 5-7 restarts. It's a real issue now.

      It turns out, that my issue resulted from a prior screen replacement, not a software update.

      So, to solve it I had to search for a solution a lot. And tried a lot. In my case, the solution was to reposition the magnet that the Hall IC observes to determine the flip state of the phone. There is a quite straighforward explanation in German here: https://repedia.de/blogs/ratgeber/samsung-galaxy-z-flip4-displaywechsel  Let AI translate the page for you, it's not too complex.

      I'm glad I was able to resolve it myself. When replacing the screen, it makes sense to take the old magnets from the old display unit with you and replace the new ones that come with the new display. That is probably, because your main board's Hall IC is calibrated for the old magnets and could have issues with the new ones. Physics.

      Hope that helps anyone.

      The Samsung Members App says everything is OK.  Don't want to try a factory reset because we shouldn't have to backup and restore after a software update.  Right now we're just waiting for the next update and hope that fixes it.  Getting an appt at the Experience Store is a painful experience.

      Interesting.  Hope that does help others.  We've not had a screen replacement though  - the only thing that changed was that software update.

      Hi I have figured out that there are no issues if you don't fold your phone, at least for me. Hopefully the same for everyone else. I know it's not a solution but it's a way to deal with it until a fix update comes.

      Has this been resolved? New update yesterday and now my phone is doing the same as everyone else on here. Diagnostics say nothing wrong with phone!

      We posted here and submitted a report via the "Samsung Members App" but have not heard anything back.  So no idea whether they are aware, or aware how many people are affected, etc.

      We're not going to bother with the Experience Store because it was a painful experience getting an appt. with them previously, and contacting Service Centre will just lead to costs.  They need to address this clear software problem.
