Why do we need this?​

Recently I've spent a lot of time trying to find an Android 9+ ROM for my S7 flat that would have those two things working: 1. fingerprint in applications like Keepass2Android and other (banking), and 2. camera to not crash after 20 minutes of video conference. The main reason it took many hours is that most ROM topics do not have a reliable issue list ("Not working" part is usually empty). If you search the thread, assuming that you know what issue to look for, then usually you may find it (but not always).

So I decided that it would be nice to have one place, where anyone looking for a S7 ROM could find a more adequate list of issues so that it would also help decide which one has the required functionality that someone needs. Anyone installing a ROM and finding there an issue, can comment here and I'll update the list. This way we will have a very nice place to look for a ROM or compare them. This can also be a good place for developers of ROMs to find out who managed to figure out a solution for a specific issue, so that they can reach out to ask for information. Without further ado, here's the list (in alphabetical order):

SELinux disabled so the ROM is less secure, some applications will complain and for good reason. There are workarounds, but you may have hard times with some banking applications.

echo issue in some other apps

* Some applications report this ROM as rooted and won't start. The reason is LineageOS comes with adb root feature by default. To fix it you will have to install root (Magisk with Zygisk or Magisk hide) to hide this state from those applications. Usually it works, but not always. It is not a bug and AOSP rules state that ROM should not fake it's status without user's knowledge, so I don't include it in the issue list. Still, it may be a disadvantage for some users.

As you can see some issues repeat on the list. The reason is if an issue is related to LineageOS on which many ROMs are based, most of them will have same issue.

One more thing: This topic is about ROM issues. I don't value here which ROM is better or worse, because there are many other aspects than just an issue list. Also please don't ask me to add here information about features. It may be fantastic but for another topic.
