@dosolly Hello, Sorry for only responding to your help now. I searched my provider's website, but there was no information other than to change my mobile phone. Therefore, I will visit one of this provider's shops as soon as I have time. Thank you again.

@kugiigi ; ...Good advice from a wise man, thank you ... if I'm wise too, of course. Concerning UT, I'll open another post about some question I have about the particularity of its adaptation for this tablet. See you soon.

@Salah I had not seen that you had opened a post after me concerning this problem and therefore, I do not open a post on 20.04 focal, and I join the conversation on your post, since I see that you have more success than me ...

@Moem @Luksus This is good news as this was a good phone with UBPorts

@vince.vs Definitely working again now.

@vince-vs Thanks a lot for your feedback. Glad I could help.

@danfro said " Actually notification LED work fine with the new kernel build: https://forums.ubports.com/topic/9864/call-for-testing-a-the-new-build-variant-standalone-kernel-method-vs-full-system-image. Just wanted to share that here too. " Hello Danfro, In version 24.04, the notification LED still does not work properly. After a reboot, with a bit of luck, it may work, but after rebooting UT, it will not work... Have you not incorporated your work on this kernel into the latest version of UT? The LED for received messages or the LED light when charging the battery is GREAT when it works... And speaking of battery charging, the remaining time displayed on the screen goes against the countdown, because when the battery is close to full charge, the remaining charging time displayed will have increased, so at the start of charging you might see 49 minutes. And then 12 hours and 5 minutes (weird, right?). Best regards

Hello, Unfortunately, I rejoiced too quickly because the Notification Led Light after an external call or a received sms or message worked only 1 time after the update to ota-2. That's strange ...
