This happens when your phone locks while rotated. If you off screen and on again (power button), then it sorts itself out.
[ROM][BETA][UNOFFICIAL] LineageOS 17.1 for Galaxy A70
- Thread starter Grarak
- Start date
The ROM is excellent. I just have a problem with the proximity sensor I suppose. I don't know if always been there with this rom but almost all the time a blinking light appears at the top left corner of the screen and is annoying. There's no fix for this? Thanks
Top left or immediate right to camera cutout?
I vaguely remember someone saying that this is due to sensor calibration problem with Los.
Unfortunately there is no fix at the moment.
Is in the top left, close to the zone of the clock. In stock this never happened but after three days with Los this just appears. Sometimes in telegram or Facebook and others just disappear
Yeah me too.
Appeared after 2-3 days on Los
For me it's was constant white dot, not blinking
Is really annoying. The rom is really good, performance is amazing. I have only this problem sadly. I hope theycan find some fix for this.
Same happens to me, blinking light but not too bright.
Using a black wallpaper and dark mode makes it disappear ?

Yes, this dot everyone is seeing is a bug with Los screen calibration. That dot is actually your proximity sensor and the screen is not compensating the overlay causing the screen to flicker over the sensor. There is no fix at the moment as you said and dark themes may make it less annoying.
Here's my quick review of LOS 17.1. Battery life is phenomenal - I got 4 days and 12 hours screen time. Almost zero standby drain. Speed and fluidity of interface is also very good. Camera is problematic, I tried GCam, then ended up with OpenCamera. No wide-angle camera functionality works. Call volume via upper speaker is very low, didn't have time to figure out third-party fix. Overall, incoming call functionality is odd - there is delay when phone rings and becomes unresponsive for couple of seconds, sometimes you would lose the call because of it. During call, ear sensor sometimes doesn't work, you take phone off the ear, screen stays black, u press power - nothing happens, you press it again and again. Frustration. So for core functionality of calls - LOS has issues. Apps from PlayMarket work fine, some Samsung apps are unavailable - Samsung Notes, Samsung Voicerecorder etc, but luckily Samsung Internet is there!
Due to camera and voice calls I'm going back to stock. Now I can only flash Android 10, due to bootloader, Odin fails with Auth error if I flash Android 9.
Due to camera and voice calls I'm going back to stock. Now I can only flash Android 10, due to bootloader, Odin fails with Auth error if I flash Android 9.
and how would u do that with android 10 bootloader installed?
I'm listening, because I tried everything.
That's great, but what happens if I would flash this over my rooted device (stock, following the instructions in this thread). I realise I could simply try it, but I don't dare to do that just now,, because I don't have time to restore my phone if it soft bricks.

LineageOS is a free, community built, aftermarket firmware distribution of Android 10, which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.
Instructions
- Go to https://forum.xda-developers.com/galaxy-a70/development/recovery-twrp-galaxy-a70-t3955984 and install TWRP (always use the latest version)
- Reboot to recovery
- (Optional) Create backup
- Reboot
- https://github.com/Grarak/android_device_samsung_a70q/releases (Choose lineage-17.0, do not download pre-release, includes changelog)
Working
Everything, but
Known issues
- Selinux permissive
- VoLTE/VoWifi not working
- Camera only shows up to 8MP
- NFC is enabled on all models, even on the ones without it (please report device model)
- Dualsim is enabled on all models, even on the ones without it (please report device model)
- Screen flickering when using fingerprint (That's normal and how optical fingerprint sensors work. Flickering doesn't happen on stock I know, but that's due to poor UI implement from lineage site)
- TWRP can't decrypt your data
Reporting Bugs
- DO NOT Report bugs if you're running a custom kernel or you installed Xposed
- Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
- If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)

Last Updated 2020-02-1311here is the proper way to install twrp ,los 17, gapps and magisk. ill provide links at end of post to make it easier. Many thanks to the dev @Grarak. Without his work, we would be without.. Note: you still can not backup\restore data but internal storage is decrypted. Also, Its the second formatting of data after setup that's getting decryption going *If you want faster access to enable wifi, pull your sim before this procedure. **You don't have to use wifi although I recommend it. You do need some kind of access to the internet. If you don't, knox will not let you flash and you could soft brick your device.
1. get the latest Android 9 Baseband/bootloader for your model using samfirm and flash using odin. setup device using wifi and enable dev options. make sure oem unlocking is on and grayed out saying the bootloader is already unlocked. shut down the device.
2. Hold both vol+ and vol- and plug into pc. hit vol+ on the next screen to enter download mode. flash twrp 3.3.1-6. when pass, hold vol- and power till device screen goes blank then immediately hold vol+ and vol- to boot back into download mode.
3. when your back in download mode, flash vbmeta. when pass, hold vol- and power till screen blank then immediately hold vol+ to boot to twrp.
4. click on settings and uncheck prompt to install twrp. go back. click on mount and make sure mount system partition read-only is unchecked
5. copy Los 17 20200213, open-gapps nano 20200127 (optional), and magisk 20.3 to external sd card.
6. Back in twrp, click wipe, advanced wipe and check ALL except micro sd card and usb otg. Slide right to confirm. DO NOT REBOOT. click back and click install.
7. click select storage and select micro sd card. click on los 17 then click add more zips. then click gapps nano (optional). swipe right to confirm.
8. once complete, go back and click wipe then click format data. type yes and enter. now reboot to system and wait.
9. setup wifi and skip the rest. enable dev options and select advanced restart. hold power and select restart then restart to recovery.
10. in twrp click wipe and format data, type yes and enter. then reboot back to recovery. internal storage should now be decrypted.
11. reboot to system and setup your device normaly. reboot back to recovery and flash magisk 20.3 and reboot to system. you should now have magisk in your app drawer, update it.

FAQ
- Can I use this ROM to boot other GSIs?
You can but I won't provide any support. If you are stuck in a bootloop or something does not work, you have to look for a fix yourself. Here is a list of things that will probably be broken when using a GSI:- Fingerprint
- Fingerprint doesn't work anymore after flashing a new build/installing magisk/etc.!
Redo your fingerprints. - I can't enroll any fingerprints!
Turn off night mode/lower night mode intensity.

I have limited time, so I will only update lineage 17 for now
