Though a step down from the Find 7, the 7a's 1080p display is still fairly standard for current phones at this size, and The Next Web was pretty happy with it, saying "colors are rich and vibrant." Android Authority agrees, taking note of the "great colours" that have "the UI shining through quite well." Usually a lower resolution means a gain in battery life, but that wasn't the case here. Not that the battery life is poor, but for a device with a 2,800mAh battery PocketNow calls it "average at best."
Aside from a lower price, the rest remains the same, and the Find 7a definitely shows that Oppo is getting better at making phones. It's not the best option available, but it's still a good alternative to some of the more popular brands out there.
