Re: Dark Mode, Samsung account & Old Unofficial 16.0

"I have the October 10, 2018 build date." - You need to update your S5 G900T to the current Official LineageOS 16.0. There is no point in troubleshooting that old unofficial build which may explain why you have a dark style problem which works fine on my S5 klte 16.0.

Official LineageOS 16.0 klte download for the SM-G900AZ, SM-G900F, SM-G900M, SM-G900R4, SM-G900R7, SM-G900T, SM-G900V, SM-G900W8 & SM-S902L models.

This post linked in my reply to you above Old Unofficial 16.0 - Google Pay, NFC Payments & Root Method includes a link to Official 16.0 for S5 2019-03-01 - Dirty Flash Report in which I described exactly how I upgraded quickly & easily unofficial 16.0 to official 16.0.

Samsung Apps & Account

"...I am wanting to use my samsung calender and MOST IMPORTANTLY Samsung Notes" - Why exactly? If it is because you like those apps then bad news, if I go to Samsung Notes in Play Store on my laptop it says "This app is incompatible with all of your devices." & if I search for it in Play Store on the S5 running Lineage0S 16.0 it is hidden & does not show up in the results.

A search for Samsung Calendar in Play Store does not return any Samsung Calendar app. You could look in Play Store's Samsung Electronics Co., Ltd. developer page to see which one of their apps works on Pie / LineageOS 16.0 like the quite good Samsung Internet Browser for example.

The problem is that Samsung does not make many apps that can run on other firmwares or other non-Samsung devices.

If what you want to do is retrieve your data from Samsung Calendar then on a device running stock Samsung firmware log into your Samsung account then "samsung calendar" export. You can then as described in this how-to Import events to Google Calendar. You can only do it online through https://calendar.google.com/ and BTW this will be reflected in the stock LineageOS Calendar which I use currently. Or import in any other calendar app you like that is compatible with Android Pie.

I did not use it but many people recommend the free app iCal Import/Export CalDAV if you have problems exporting natively in Samsung Calendar.

You could try this search "samsung notes" export. I know that you can't import in Goggle Keep but maybe some other note apps can.

"...lineage was not supporrting SAMSUNG ACCOUNT . The one I speak of use to be located at Settings>Accounts >Add Account>(here). Right now it only allows Google, Whats App and Duo." - As I explained above there are 2 ways to add an account: in Settings > Accounts > Add account but also through some apps > Settings if they have that feature like I did with Samsung Internet Browser > Settings > Sync with Samsung Cloud > I signed in with my Samsung account credentials & even with the Samsung Cloud toggle that appeared after signing-in switched to off I can see in > Settings > Accounts > Samsung Internet (screenshot).

If you don't install any Samsung apps then there is no point in adding a Samsung account in Settings > Accounts as nothing can use it in LineageOS so that is probably why it is not offered unless you install a Samsung app. See the attached screenshots.

"Latest" will not mean a thing after the next update which should be tomorrow. ;) Why not include the exact version which is good practice IMO?
