Ok, thanks. :)

Great ;) (off-topic : can you tell me what is that theme name? Black color one.)

Installed new update. Things look better. No problems until now.

I have downloaded it, just waiting for battery to charge till 100 before I install it. Will tell my first impressions after that. But about battery, wifi and charging status, I can only tell after few days.

Yes for s8 dual sim KSA Model. Which is yours?
