Hardware Switch misbehaving when a microSD card is inserted

[BBR]

With a microSD card on my Nintendo Switch the touch screen stops working.
When I wake up the console from sleep it always tells me that the microSD was disconnected and that I need to power off the console.

Tried two SD Cards. Sandisk Ultra 16GB and Samsung EVO 128 GB. The second one formatted with GUIFormat.

This is an old model. Bought used two months ago. First time trying to use a microSD card.

I would check actual slot, may be something get in.
You can reach card slot very easy just by taking back housing off:

One screw on the top (Philips)
Four on back (Tri-Wing)
Two on the bottom (Philips)
One on each side(middle one on the rail) (Philips)

When you will open console you will see card slot flex-cable, may be connection is bad or water get in, pins in a slot might be bent also.
Either way i hope that is not a motherboard issue.

Yesterday I tried taking of the slot, cleaning it a little with isopropyl alcohol and put it back in to no avail.
I also swapped the piece with a friends slot and did nothing to fix the error, my piece worked as intended in his console.
I removed the shield to take some pictures, here they are:

I am out of ideas, i would check elements around, compare multimeter readings with working switch to make sure hardware is good.
Over all pictures looks good for me, may be it's a software issue or maybe cards are faulty, did you tried to check those cards in your friend switch?

If you're fine with this:
I've recently fixed an MicroSD issue and I've got enough knowledge around fixing various random switch issues;

I'll be glad to help you out if you can micro solder and have a multimeter at hand.

I realize this is many years later, but I wanted to chime in to give you some validation that you're not the only one experiencing this. It's frustrating because I cannot find very many people reporting this problem.

I have an old swtich that exhibits the exact same behavior: touch screen inoperable when the SD card is inserted, everything else works fine until I put the switch to sleep, and then it complains that the SD card has been removed. After a reboot, everything works fine again (except for the touch screen of course) until it goes to sleep. The touch screen also works fine when there is no SD card inserted.

I have also tried multiple different SD cards and I also tried replacing the card reader with a brand new one. Nothing fixed it.

It's unfortunate because it makes Atmosphere really difficult to use because you can't put the switch to sleep, so it's very tethered to my PC so I can inject the payload when I turn it on.
