The Samsung Galaxy J1 is a decent entry-level device that, just like all of its peers, will be made or broken by its pricing.
It's a reference to the idiom "make-or-break". The meaning is: the pricing of the new model will be the crucial factor that will either make it a hit or lead to its failure on the market.
It's an entry level device, hence probably cheap. A low price might attract buyers, but a low price is often associated with a lack of features. This could discourage those who prefer buying more expensive and feature-packed products.
If a company makes a device that is poor in features but fails to make the price low enough, consumers will consider the deal a rip-off and won't buy the item. This is especially important because those who buy entry-level phones are more sensitive to pricing than those who buy expensive phones. You've got to make your pricing just right.
