The Samsung Galaxy S21 lineup will be unveiled on January 14 and ahead of the announcement, official marketing renders of the S21 series have surfaced, which don't reveal anything new but corroborate previous design leaks.
The S21, S21+ and S21 Ultra will all pack punch hole displays, but the vanilla and Plus variants will come with triple camera setups, whereas the Ultra model will feature a quad rear camera (fifth circle houses Laser AF unit).
While Samsung hasn't divulged much about the S21 lineup, previous leaks have left little to the imagination since we know what the trio will look like, the specs it will have on offer, and the amount of money you'll have to shell out to buy one of these flagships.
That is actually better as on non metal back phones the same amount of heat is generated but it is trapped inside. The metal back can act as a thermal mass to improve performance.
