You just can't do that with any current Galaxy S4 kickstand case.
At least not as well as the kickstand case I had on my Galaxy S3.
I had the black/red one and it was nice looking. But the kickstand was PERFECT. Not only was the phone super stable in portrait, but also horizontal.
There are some kickstand cases available for the S4, but nothing that comes close to as perfect (IMO) as the S3 case was in portrait mode (standing up, not sideways).
So, I tried several S4 cases and they all sucked. Every single one broke pretty quickly and none were overly stable. My old S3 kickstand case lasted a year and the kickstand in it still worked perfectly. It was just solidy built.
Anyways,I decided to just build my own. A DIY kickstand case.
First, I went to Kickstand4U website and ordered their add-on kickstand.
Then I went and found my old S3 case for about $10 on eBay. It was an UGLY color, but that didn't matter. All I wanted was the kickstand from it. These cases btw, all have either a matte black kickstand or a white kickstand.
Then I compared the Kickstand4U (left) vs. the S3 kickstand from Qmadix (center, with new S4 Spigen case on right).
As you can see, the Qmadix kickstand in the middle is larger in size, made for large phones like ours. And it's going to be more stable than the smaller Kickstand4U. I really hope Kickstand4U eventually makes a larger kickstand because otherwise, I really liked the quality & build of this kickstand. It also had notches that let you select an angle for the kickstand.
So I proceeded to take apart the S3 Qmadix kickstand case.
Then I cut out the kickstand from it.
My Dremel is old & wimpy, so I used a high power Ryobi instead.
But any newer, decent Dremel with cutting wheel will work just fine.
Then I sized up the cut out kickstand.
Then I cut out a suitable sized hole into my new Spigen Slim Armor case.
You'll note the kickstand itself is larger than the hole in the Spigen.
This is so I have a mounting surface to glue them together.
Then I used epoxy to glue the kickstand into the Spigen case.
And then I cut out a hole from the Spigen inner rubber case so the kickstand would fit and not bulge out.
I also put scotch tape on my battery cover just to make sure the back of the kickstand doesn't scratch the battery cover.
What you see in the pic is the inner rubber case, then the outer hard plastic case, then the large black part in the middle is the kickstand that's glued to the outer hard plastic case.
As you can see, the inner part of the kickstand mount and the cut-out of the inner soft plastic case is perfectly level.
So no buldging at all!
And voila. I'm freaking happy as hell. Finally got a well built, great working kickstand case.
Next time I'll slow down and make the cutout a little nicer. I learned a few tricks I can apply next time.
The cool thing is you can buy any color shell you want by itself from Spigen for $10.
You don't have to buy the whole case over again. They let you buy the shells by themselves.
Wow, that kickstand is so nice when it's built INTO the case rather than stuck on top of the case.
You can hardly see the kickstand coming out of the case.
