I am currently using this phone. Its one phone that has not let me down in any condition. Vivo is a new company in india but trust it as it has been for years.
My v1 max is a beast in all aspects. The 5.5 inch screen is nice and vivid.
Octa core processor is good not laggy at all, camera quality is above average, and the speaker’s on the device yes its has dual speaker’s on it and I can bet anybody that there is now phone with this type of loud and clear sound in the market not even htc boom sound can compete with it. Its my favorite phone of all time after nokia n73.
