That's odd. My Fold 4 had wifi/Bluetooth issues after 5 months and I had it checked by Samsung. They said they had to replace the entire screen and battery even though I had no problem with either. Something about components being connected to each other via the hinge so the only way to fix the connectivity issue was the replacement. They did it under warranty so it's like I had a brand new phone after 5 months.
Model is very good looking only one problem battery 🔋 mah 4400 only no long backup
I have soft go and update
Will you please post the sensor sizes on the camera's
Im not ready for fold..I like as idea but i want more to be done samsung..
Nothing in the middle of screen for example..
Lets see fold 5...at the moment after im with ultras every year since 2019..but no s20 ultra

Am I only person who love crease on main display? It is like anti-stress effect when I slide my finger over it again and again. It is so delicate.
Unfortunately I am user of this bogus product.as they said 100 times I can unfold and they tested 200 k times but I don't believe it so.
In one + year may be I unfolded it 500 times and some days ago it automatically broken.
Broken isn't problem for me.
Problem display price 1500 USD where I can buy new and same phone by 1000 bucks.
Note7 owner, 03 Sep 2022 I was hoping after 4 tries at it Samsung would have gotten rid of the hedious crease. It's easy to forget once you get used to it. I also hated it when samsung first introduced the OG fold and have wished with every iteration hence that they would get rid of it. Now that I use the Z Fold 4 everyday, I'm surprised that I don't really mind the crease at all. It doesn't in any way detract from the amazing experience of a foldable Samsung device.

Str... moreThat 100-120hz fluorescent light flicker only exists in older magnetic ballast lights. I had eyestrain/migraines induced by those lights decades before LED lighting and OLED displayed existed. It's pretty uncommon to encounter that today, unless it's an older home or office that hasn't had any work done in the past 15-20 years.
As for OLEDs or LED backlit LCDs, I've found some where the flicker is visible as an annoying brightness fluctuation/flutter at typical brightness settings. I haven't looked at one long enough to get a headache, but I'm fairly confident it would happen from the amount of discomfort from just looking at it for just a few minutes.
The same goes for some OLED phones with PWM frequencies between 200-250hz, but usually only at lower brightness levels. This is because at lower levels, the "off" duty cycles are longer and more noticeable. Some PWM implementations are worse than others, because the on/off cycles aren't paced evenly (for example, off-off-on-on instead of off-on-off-on for halving brightness) and effectively emulate an even lower frequency. My current and previous phones have 242hz and 250hz respectively, and neither caused any discomfort unless brightness is very low. Even then, it's not really as visible as with a 120hz PWM LED backlight.
I can only assume my threshold for sensitivity is somewhere between 120-200Hz based on all the known PWM displays I have personal experience with. The point at which I can see a noticeable flicker seems to be between 60-120hz. Of course, the implementation of PWM cycles across different brightness levels also has a significant impact on whether any particular display will cause problems.

Speakers are very loud, don't need additional speakers.

Samsung will use the 200MP as it's main selling feature but it's mostly pixel binning which will break down to 12.5MP at default. I like the Fold but I can't pull the trigger for a couple of reasons. With the price, it's very expensive and without external storage you'll need 512GB. Then you don't get much beyond a larger unfolded display for the high cost. Battery is too small, cameras are average and there's no excuse a device this large can't include a MicroSD. Secondly the Crease, Others have found a way to overlook it but I can't help thinking it would only look worse over time.
