Oppo may not be a household name, but the handset maker is big in China and its phones have now become available in the UK through Carphone Warehouse. The RX17 Pro (also known in some regions as the R17 Pro) is not the company's flagship handset -- that accolade goes to the £700 Find X. However at £479 (at the time of writing), the 6.4-inch Oppo RX17 Pro is a direct competitor for a current favourite in the value-for-money stakes -- the OnePlus 6T (NB: Oppo, OnePlus and another top Chinese brand, Vivo, all share the same owner -- BBK Electronics).
