folks, i see 2 android icons in my a8+ since yesterday, any clue what is it abt

Other mobiles r in Android P testing phases and i did not received a android O update.. why did i even bought this phone.. fr what joy??

i've been seeing this msg very often on my screen.. just like a flash msg.. it says failed to load please try again. what does this mean? i even cleared the cache partition.. any suggestions here please.

eager to know.. what if i change my screen mode from adaptive display to basic on my a8 plus.. does it help in battery consumption.. in any way樂樂樂

when can i expect oreo update for my phone..
