What the Critics Are Saying...


The Oppo A78 has a big screen, a premium feel, and many other traits that let you forget it's a cheap Android device... as long as you can handle its poor camera performance and a tidal wave of bloatware.

The big appeal of the Oppo A78 5G is its price. This is a proper budget smartphone, but which still strives to give you lots for your money. Notable plus points are the 5000mAh battery and 33W fast charging to keep you up and running through the day. The disappointments on the phone are all at the r...

The Oppo A78 5G is another budget phone that boasts great battery life and decent performance even if the 720p display is a little soft. Much like the TCL 40R 5G, it shows that you don’t have to break the bank for a solid phone, even one with 5G connectivity.

The A78 5G is a cheap but commendable phone with some strong qualities, but the compromises Oppo has made on software and build quality means it won’t be a guaranteed hit with everyone.

- David Blake, Tech Advisor

Every budget phone has its downsides, but surprisingly zippy performance and a reliable battery life make the OPPO A78 5G better than most.
