[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] ctrej:
This ROM does not show if the device uses normal or quick charging directly. But you can read out the current that goes in or out of the battery and use that as an indicator:

use Device InfoHW or similiar to show the charge/discharge current

discharge the phone to 70% or less, if it's higher the phone may limit the charge current independent from the source

connect to a normal USB A port of your computer. It should charge with 500mA or less (see footnote)

connect it to a Quick Charge capable power supply/ charger (like the included one). It should charge with up to 3000mA

The phone detects the power source with the data lines and limits the power draw from a computer to prevent any damage to it. If it detects a higher power source, it draws more power and you can conclude that the data lines in the cable and connectors are ok.

footnote: USB2.0 delivers by default up to 5V/500mA (2.5W). The phone takes about 100mA (0.5W) to power itself (depending on screen brightness) and converts the rest into 3.7V/500mA (1.85W + 0.15W conversion loss).

You definitly need a new firmware version for the latest update. I do not know how the region-based versions differ, but it's likely that the vast majority of code is identical. Therefore this ROM likely works with a matching swiss firmware (= released on the same day as the recommended one). That is also kinda proven by the fact that you were already running RC2 without the recommended firmware fo a while :P. I would properbly try the firmware files from Stef4n842 first, the installation is easy and most likely there will not be any noticable difference to the swiss version. If there are any, you should be able to install the matching swiss firmware later without issues.

Installing a new firmware should not effect your data at all, but I strongly recommend you to backup all important user data just in case. Additionally you can create a backup in TWRP, select the partitions recommended by modpunk: https://xdaforums.com/showpost.php?p=83183429&postcount=677

Well, in my initial test I only used the App NFC Tools to verify that NFC is working at all. I do not use google pay, but I was able to reproduce the issue with the AusweisApp2. Initial detection of the card is ok, I can start pin change/setup but not complete it. (I did not use the app on my privious phone (it didn't have NFC) and thus I can not read out any data without setting up a custom pin first.)

I think for "simple" tasks (like reading tags) NFC kinda works, but it seems to struggle with more complicated/ safe critical tasks. Maybe most users don't use NFC and thus nobody reports issues with it?

I've used this ROM for a few weeks now and never noticed any issues with wifi. My S10e is on v1.0 now, but RC2 worked just as well.

Does the issue persist with different wifi networks? Are you using 2.4GHz or 5GHz? Does your router change the wifi channel/band based on channels used by neighboring wifi networks? This feature is supposed to help in dense urban regions, but maybe the phone has trouble switching on-the-fly from one channel to another. If possible, try disabeling this and select a fixed, moderatly empty channel instead. It's just a guess, but it would explain the seemingly random issues.
