@donieck I have reinstalled it via ubports-installer (RC channel). There is some kind of problem with the DEV channel build.
Recovery works - hold power button, after the screen is restarted, release power button and hold volume up button until warning about unlocked bootloader appears, then release volume up button and wait for recovery.
@embeddedmz said in My final feedback after 5 months of using UT on a Xiaomi Mi A2:
- Volume of headphones used with a USB Type-C to 3,5 mm adaptor is low even if the system sound volume is at it highest value.
Boot device to recovery screen. (restart + Volume Up) and connect to PC. From Terminal do:
adb shell mount /dev/block/bootdevice/by-name/vendor_a /tmp
adb pull /tmp/etc/mixer_paths.xml
sed -i -e '/RX1 Digital Volume/{s/72/81/}' -e '/RX2 Digital Volume/{s/72/81/}' mixer_paths.xml
adb push mixer_paths.xml /tmp/etc
adb shell umount /tmp
adb shell mount /dev/block/bootdevice/by-name/vendor_b /tmp
adb pull /tmp/etc/mixer_paths.xml
sed -i -e '/RX1 Digital Volume/{s/72/81/}' -e '/RX2 Digital Volume/{s/72/81/}' mixer_paths.xml
adb push mixer_paths.xml /tmp/etc
adb shell umount /tmp
You can try to change both slots.
Restart device and enjoy.
Note: sed command is changing volume 72 to 81 in this section:
<path name="headphones-ce">
<path name="headphones" />
<ctl name="RX1 Digital Volume" value="72" />
<ctl name="RX2 Digital Volume" value="72" />
</path>
- The web browser : when watching a video on Youtube, it's impossible to move the seek bar to another time and when we try harder there's the contextual menu of the browser that appears.
You can try tapping (double, tripple etc.) right side of video to forward, left side to backward seek.
@prog-amateur said in [HowTo] Alternate way of saving battery when using 4G/LTE:
I have used the "lte" modification in the script without success. Then I have reboot my phone and the script was working perfectly.
Thank you for the report, you have to use "restart lte-battery-saver" to apply script changes. I will add a note about it. It looks like "lte" is more generic then "any" so I'll change the script.
@domubpkm Testing MR is not an option for me. I'm able to test QA only. And I think more important is the answer to question 1. about security.

@stanwood
Hi, thank you, I talked to him and it looks like there is no problem with missing kernel option. I made an issue: https://github.com/waydroid/waydroid/issues/268
@stanwood said in Waydroid reboots my phone connected by wifi:
@soulrock So I checked with Rudi.
He just told me that this device hasn't got the appropriate kernel patch, this explains why you have some issues.Please contact the porter, or wait until a fix comes in a future OTA update.
@stanwood
Hi, would you please specify what patch is missing or ask Rudi?
Here you can see related kernel changes: https://github.com/ubports-xiaomi-sdm660/android_kernel_xiaomi_sdm660/commit/36668a5cb62a916e2bcde178fce808f34726856f
@mkarpicki No, I meant cellular data.
@mkarpicki I've tried WhatsApp and it's working as well with cellular data.
@mkarpicki What apps are you using? Is e.g. Whatsapp running without problems?
@lakotaubp said in Dual-SIM + OTA-20 on Mi A2:
If you are on OTA20 yoh will not get a new stable version until the next OTA is ready.
I disagree, the procedure I described works in my case - Xperia X and Mi A2.
@PhAndersson
If you are unlucky with it, do what @Lakotaubp said.
@phandersson said in Dual-SIM + OTA-20 on Mi A2:
Just upgraded to OTA-20: the upgrade process itself went flawlessly, but the SIM card in slot #1 is no longer detected!
Hi, I faced the same problem. I remember it was upgraded via delta, not full image. After full image "re-upgrade" two sims appeared in my case.
You can try this: Through the settings change channel to devel, close settings, start settings again, there should be devel upgrade available, don't upgrade and change channel back to stable and close settings again, now when you start settings there should be stable upgrade available - full image (cca 500 MB). Do the upgrade and you will see.
@soulrock
Hi, I've tried Messenger again and it's the same problem - when on cellular data, it runs smoothly. Great finding, thank you. 
@soulrock said in Waydroid reboots my phone connected by wifi:
@c4pp4 I have gapps
Maybe some package from GApps can cause the problem, because I have similar experience with Facebook Messenger installation. It runs after installation without problem, sending messages, taking and sharing pictures etc., but after next waydroid start (after cca 5 seconds) the app freezes the whole system. Anyway I didn't try to turn off wifi and use cellular data instead to check if it's the same problem.
@soulrock said in Waydroid reboots my phone connected by wifi:
after about 10 seconds it freezes and the phone reboots itself.
Hi, I would like to ask, this is happening on vanilla waydroid or you installed some additional apps already?
@yoni I'm not expert but I can imagine ubuntu system don't turn off cellular data on android side, so there is no connection within ubuntu, but there is connection in android layer.
@yoni Yes, there is no connection in Morph.
@yoni Maybe it was something to do with TELEports or RC image because now it's without problem and before the latest test I updated both.
I think it's some kind of bug because I forgot to turn off script and that's why it was saving battery. In my case when 4G is set and turned off cellular data - it's not saving battery. When 2G is set and turned off cellular data - it's saving battery. I think it shouldn't matter what is set. 
@domubpkm I'm not going to do that. Use the first or second script if you need connection.
@yoni I did that when it was idle.
