[Samsung Galaxy S 5 Unified Development] curiousrom:
Official 16.0, WiFi 2.4 GHz vs. 5 GHz & Substratum

Thanks :good: for the Thanks. :cool:

"...I dont know If ive installed the official or unofficial build" - Hopefully you installed the official 16.1. Check > System > About phone > press on Android version 9 > LineageOS version > if it says 16.0-{date}-UNOFFICIAL-... that's not good. If it says 16.0-{date}-NIGHTLY-... you are OK and > Settings > System > Advanced > Updater should work.

You did not say what is your exact phone model so I can't post a direct link but this is where to get official LineageOS firmwares: https://download.lineageos.org

Yes the S5 G900M LineageOS 16.0 is my daily driver. The GSam screenshot posted above is not about average battery life. The "Battery History (2d 9h 26m)" in it just means that I installed GSam on my current clean install just 2 days ago when I made that screenshot & it collected only 2 days of battery history.

On my previous unofficial 16.0, GSam said after accumulating battery history data for 4 months:

Average Per Complete Charge

Battery Life: 1d 6.9h (6h 11m Active)

Screen On: 5h 6m (7h 1m Max)

In the GSam Battery Monitor screenshot attachment in this post that I made yesterday with 4% battery left it says:

Used 96% in 1d 7h

Average Per Complete Charge

Battery Life: 23h 55m (6h 23m Active)

Screen On: 5h 50m (5h 42m Max ?)

Since Mar 16, 2019

So the data is only for 4 days of battery history & is skewed by frequent rebooting & connecting the S5 & installing stuff on a new install as you can see in the second attachment.

I apply the optimization tips described here including using Privacy Guard Advanced: Remove Animations UI Speedup Test - Taming Google & Apps.

Everything is relative & especially battery life with so many variables including how old is the battery & if it's a fake with a weight of 40~40.2 grams or a 45~45.2 grams original Samsung for S5.

"...I hate to have to use magisk only to be able to use substratum" - In the Play Store substratum theme engine page it says @ the present:

What's New

v1015:

- Fix settings crash faced by some users.

Magisk v18.0 is the only supported version now!

"...disconnection happens when I am connected at 5GHz and there is no disconnection when I am connecting at 2.4GHz" - From NETGEAR Support What is the difference between 2.4 GHz and 5 GHz wireless frequencies?:

You have to rule out internet connection lost by the network itself. Maybe carry an other device next to the S5 to see if the connection breaks at the same time.

If you have a Windows 10 PC check Windows Support Analyze the wireless network report which saves a wlan-report-latest.html to your PC with a 3 days history which you can view in your browser. I attached a partial screen capture from the Wlan Report.

Today my home internet access crapped out (1 to 10 days to have it fixed) & the breaks in the graph corresponds to the ones reported in GSam. I am posting this using the S5's LTE data internet connected to my laptop via USB tethering. One more caveat of GSam is that in Chart the LTE internet connection is reported as Wifi.

"...I can't seem to find anymore the option to select the operating band for wifi in the settings. - Can't find that option either.

I don't have access to a dual band Wifi network but if you connect to yours & press on Wi-Fi > connected network's name cog is there a band selection option?

Sounds like a good way to mess up your setup and may requiere a clean install eventually. :eek:

To this pretty negative Substratum review the dev replied: "...also disable auto update on the play store for the apps you have themed so they don't update unexpectedly. Set a time when you can update both apps and themes at your convenience. Support chats are linked in the app description - Char".

So maybe when you apply a theme after updating LineageOS there is new stuff in "Android System" which the theme can't handle yet?
