The Realme C1 runs on Coloros 5.1.
Coloros 6 is based on Android 9 Pie,
which works well and also offers many shortcuts and gestures.
Just like the Realme 1, 2, and 2 Pro,
the Realme C1 also comes with Android 8.1 Oreo with Coloros UI on top.
It is also partly due to Oppo's custom Coloros skin which does not offer a lot of animations
or anything that would slow down browsing experience.
Based on Coloros 5.1, and inspired by Android 8.1 Oreo,
the phone is powered by a 4230 mAh battery and runs on the Qualcomm Snapdragon 450 processor.
The Coloros 6 is essentially based on the Android 9 Pie,
that runs perfectly smoothly and even provides the users with plenty of shortcuts as well as gestures.
The Realme 2 runs Coloros 5.1 on top of Android 8.1 Oreo,
and our unit had received the July security patch at the time of writing this review.
