[Samsung Galaxy Z Fold 4] Q-Prof:
Wanted to share with you all, a really good case that is worth the money for this phone, and I am really happy with it.

The case is intended to put on and leave on, hence the adhesive films on the inside of the front cover, the back (with yellow cushioning) just clips on with a strong solid tight fit. The front cover bezel/lip looks to be about 2.5-3mm deep, but accessing the right side soft menu still good. My finger size is about average/medium size and I have no problem also accessing the power button and fingerprint sensor on the side beside the s-pen.

Used the glue adhesives on the front screen that were already applied, just had to pull off the backings (They also included an extra set of glue adhesive strips for a second mount if you ever need to take off and put back on) and it fits perfect, lines up with all the holes and speaker grills. The back piece with the hinge cover (with 2 spring loaded hinges), protects the back and fold hinge while the lip around the camera protects the camera lenses. It too also has perfect alignment with holes and has lots of clearance with the USB C port fitting. The hinge cover protector also gives you something to hold/grip when the phone is unfolded.

Suggest you first get a front glass screen protector (I used the Spigen Glastr Ez Fit for perfect alignment and easy application) for the front and camera lenses protectors also before applying this case.

This quality case feels very good, smooth, solid, elegant, and provides a great grippy feel. More importantly, I feel more confident holding the phone with this case on, as it feels like it could weather some accidental mishaps and protect the phone.

In my pictures, you will notice I also put a pop socket on the back centre for four reasons:

1) use for general holding in hand, even more support than the hinge cover protection bump when fully open

2) use as a kick stand for front screen and/or the unfolded full screen

3) use for a magnetic mount that I have in my car - so phone can sit in folded vertical or horizontal orientation and also unfolded orientation, using a pop socket flat mount with the metal plate stuck on the back of it- I just slide my pop socket into the pop socket flat mount holder and then attach to the magnetic mount, which also allows me to:

4) wireless charge at home, by twisting the top half of the pop socket half a turn to remove, when it is pushed in, which will allow a closer clearance for wireless charging through the case as it is all plastic

One critical point based on the design of the spring loaded hinge cover protector, when you do unfold/open the phone to full screen, and you are using the back screen for taking a selfie, you loose about 1 cm of view area on the left of the front screen. This minor con is something I can live with as this is in only this situation and for the design, it is a great compromise having that hinge protection.

In closing, I am really happy I got this case. I was originally worried that it might be too bulky, eventually ending up removing it for a thinner/smaller case, but I think it has a great balance of protection, holds the s-pen on the front side of screen keeping it's thickness down (compared to the Samsung pen/kickstand case, or others in some cases), and one of the few cases that protects the hinge, allowing the phone full protection around the whole phone. Hopefully you found this helpful for your situation.
