The timing of the new iPhone SE — which goes on preorder today and arrives April 24 — could not have been better for Apple. As the coronavirus puts millions of people out of work around the world, a $400 iPhone (£419, AU$749) will appeal to people in search of a budget device that does it all. But Samsung has a $400 competitor already on sale (£329, converts to AU$634) — the Galaxy A51 — and on paper at least, Samsung’s chances look good.
