Our take

Is it any good?

The Y31 5G is a rugged budget phone sold in one version, 6GB + 128GB, at ₹27,999, in Rose Red and Diamond Green. It is for people who drop their phones and would rather not rely on a case to save them.

The money buys IP68 and IP69 ratings, Guardian Glass on the 6.68-inch 120Hz screen, a 6,500 mAh battery with 44W charging, a 50MP main camera and a Snapdragon 4 Gen 2, plus a hybrid slot that takes a microSD card up to 2TB.

The catch is that it is the older model. It runs Funtouch OS 15 on Android 15, its screen is an HD+ LCD, and it uses Bluetooth 4.2. The Y31t 5G has the same chip, a bigger 7,200 mAh battery and Android 16, and starts at ₹26,999 for 4GB + 128GB, so decide how much RAM you really need before picking the Y31.
