Re: Tab4 8 now has Android 8.1

I had this problem when initially attempting to update to 8.1.

 

The problem was insufficient free storage to download the update. Clearing some space and trying again solved the issue.

Re: Tab4 8 now has Android 8.1

Has anyone been able to deactivate the dynamic brightness they've introduced with the Oreo update? It's horrid! Some darker websites, like that of Netflix, are almost impossible to read, when the predominant color on the screen is black. I've looked through the options, through and through, but there's no way to disable that.

 

NOTE: This does not refer to the automatic brightness control, that uses the light sensor, but the dynamic brightness adjust that automatically dims your screen when the image is darker and brightens it when there are more whites.

 

I'd really appreciate some way to turn this off. If they could also bring back the magnetic unlock, that would be great.

 

Thanks,

Kal

Re: Tab4 8 now has Android 8.1

I don't have any dynamic or adaptive setting but don't see any automatic dimming, the new ultra-dark apps all have readable white fonts.  Googling turns up this, saying Nova Launcher (replacing the default Lenovo launcher) can disable it:

Default lighting for me is too bright for reading ebooks, I've got the screen brightness set to 15% with a bit of Night Light to tone the whites down.

Re: Tab4 8 now has Android 8.1

Hi buddy.

 

Yes, I found the same article, as well. Actually, it was stupid of me posting my question here, in the first place. I own the Tab 4 8 Plus, but it was too late when I saw where I had already posted my question. Smiley Happy Anyway, what I found is that the feature is called CABL (Content Adaptive BackLight) and is a driver issued by Qualcomm. So, it seems to be a feature of the SoC itself, rather than a deed of Lenovo. I'm looking into the possibilities of disabling CABL also via ADB. But I will try with NovaLauncher first.

 

Anyway, my call to Lenovo stays - please, make CABL an option, don't enforce it. It really destroys the experience!

 

Thanks,

Kal
