HONOR 400 Smart vs OPPO Reno 16

Our Verdict: The HONOR 400 Smart gives you the larger 6.77-inch screen, while the Reno 16 is crisper at 461 PPI. For camera specs, the Reno 16 has the 50MP front camera, so treat it as an advantage in hardware rather than a guaranteed photo-quality win. Storage favours the Reno 16, which tops out at 512GB rather than 256GB. Buy the HONOR 400 Smart if a larger screen is central to the upgrade; buy the Reno 16 if a sharper display carries more weight.
