LineageOS 20.0 (Android 13) [Signature Spoofing][OTA updates] for S7 Exynos

[vizolover]

Do you use stock camera app or an different app like gcam port, open camera etc ? What gallery app do you use and which camera settings do you use ?

Yes stock camera app from the latest build. Selfie can only shoot in landscape orientation. Opencam and gcam work as expected. Stock gallery and Simple gallery pro produce the same result, stock camera settings.

Video on the other hand has the correct orientation

do you guys have Bluetooth problems? I have had it stop working all together. IT will not find devices. It works at first then after using it for a few hours. It also happens on my poco f3 so I believe android 13 isn't working right. I do like the rom though.

 

[Techguy777]

I also have static when playing music. I did get it working by clearing the data for Bluetooth 13 app

 

[Techguy777]

Its been a few years since I played with the S7. Did it get only like 3 hours of battery Life? The apps say its using 33 percent battery an hour. Is that the rom?

Hello Forum,

just have a question for understanding the right way:

Actually I run my Samsung Galaxy S7 with LineageOS (LOS) 19.1 and NikGApps 12.1.

For installing LOS 20.0, must I do the install from scratch?

Means, first install newest TWRP with Heimdall and then the LOS 20.0 plus the corresponding NikGApps 13?

Or can I just load the installation file of LOS 20.0 and of corresponding NikGApps 13 onto the SD-Card of my S7 just to do the upgrade for both with the built-in LOS 19.1-upgrader?

Hey, I was wondering if you could add a blue light filter where the screen goes orange. There's gray-scale, but I believe that's not effective at reducing the amount of blue light.

I've been using the rom for about two weeks now and got two bigger issues:

While it worked fine in the beginning, I'm getting massive slowdowns now from time to time, anyone else has related issues? For me it happens especially with the camera and Telegram (when using reactions, my keyboard won't work for several seconds).

edit: I wiped Cache + Dalvik-Cache already, but it doesn't help.

Second issue:

The flashlight will turn off once the screen gets locked or turns off due to inactivity. I guess this is a bug and not a feature, right? I read that there are issues with long-pressing the On/Off button for activating the flashlight (which worked in previous LOS versions), so is this related to it?

Besides that the rom looks and feels great!

For the phone sometimes hanging issue (it also results in bluetooth underflows and hence choppy/missing audio while the screen is stuck) I tried getting some logcats from the moment things started going south. Apparently the phone hangs so hard that logcat timestamps are jumbled up.
Doesn’t seem to be highly dependent on which apps in particular are opened, just on the system (RAM?) being under heavy load which it doesn’t deal well with.


/edit: last_kmsg after I had to force reboot the device after not reacting for several minutes

My device is set to german language, so i didn't know how exactly its called. But search for settings -> display -> colors and activate nightlight

Good to know I'm not the only one with this issue. I assumed these lags are not tied to specific apps, but it makes sense that e.g. camera app requires a lot of ram. I hope we find a solution for that.

edit: I checked the Memory usage in Developer Options, and after Android OS (~1.1GB), Telegram is the second most memory demanding app (~700mb). It makes sense lags happen when there are issues with memory handling.

Hi @dan54140

thank you for your response.

Actually I run TWRP 3.6.1_9-0-herolte on my S7, and I wonder if this would be ok for the LOS 20 too?

I have upgraded several smartphones for friends to LOS, but in each case from StockROM.

With the LOS 20.0 and my own S7 this would be the first upgrade inside the LOS, therefore I was unsure, how to handle.

But I still have downloaded newest TWRP for the S7, its 3.6.2_9-0, and also LOS 20.0 and the NikGApps 13, and in next week I will do the upgrade.

What I really miss, would be an LOS upgrade system like with the StockROM, so that one must not install everything new, because this is a damn bunch of work, and as a handicaped person I try to avoid such long periods of sitting at my desk...

Hi @ssauger,

I am from Germany also, but because English is the ruling language here, I reply in English.

Could you please tell me, where that settings for the nightlight is to find with the german language menue?

Or is your S7 in LOS 20? I still run 19.1... will upgrade next week.

Yes, my device has LOS 20 installed. If it is also available in 19.1, i think you will find it in Settings -> Display too.

Thanks, have found it in 19.1 under Settings -> Display -> LiveDisplay -> Display(Screen)mode -> Automatic
(in German: Einstellungen -> Display -> LiveDisplay -> Displaymodus -> Bildschirmmodus -> Automatisch)

It's always recommended to do a clean install (wiping data and installing from within TWRP) when changing the ROM or LOS version (e.g. from 19 to 20). But once you run a version (e.g. this LOS 20.0 version), you can install regular updates from within Android without having to wipe anything first.
