Reporting in.

Finally the software update give the option to adjust the brightness with the quick setting pull down from the top.

Maybe i slow po
But it is still new for me... i always rely on that "control panel / setting widget" to set my brightness one..
Else i have to go into the setting to adjust the brightness level or set to auto brightness.

attaching the online image..
see the huawei camera user interface? the top right, second button.. play with it and see any difference.

Luckily get to see the comments here.
So better dont update?

i got the update notification yesterday.. and i didnt go for the update.
Leave the phone overnight and somehow it just updated by itself??
Anyway, i also notice the battery drop faster
I am P20 Pro user

any comments on battery performance? or like the last one, got worsen.

Let me guess..
If u put ur SIM to other phone, is the issue still there?
Is it because u are not subscribed to the caller identification service by your telco?

Did u recently change telco plan?
Or what changes u have recently?

Or if u have been using the same telco plan, have been using the same phone for some time...then suddenly caller identification failed to work?

Does the incoming call show number? Or just show unknown and cant even see the number.

I only know in Singapore, caller ID need to pay / subscribe for the service. If dont subscribe, then it show unknown.

Also mentioned previously, take ur SIM to other phone and see if the problem is with the phone, or with the SIM card or telco.

I think just go to settings and search for carrier..
Should be able to find display carrier name.. then u know what to do.
