Oppo seems to be all-set to expand its smartphone lineup with two new models, namely the Oppo A53s and Oppo A73 5G. While the Oppo A53s has surfaced on Amazon Germany, specifications and renders of the Oppo A73 5G have been leaked on Twitter. The Oppo A53s is quite similar to the Oppo A53 2020 that was launched in Indonesia in August and debuted in India shortly after its initial launch. The Oppo A73 5G, on the other hand, appears to be a 5G variant of the Oppo A73 that launched last week as a rebranded version of the Oppo F17.Oppo A53s, Oppo A73 5G price (expected)The Amazon Germany website has listed the Oppo A53s with a price tag of EUR 189 (roughly Rs. 16,400). The phone is set to be released in the country on October 13 and is currently available for pre-orders through the online marketplace in the Electric Black and Fancy Blue colour options.

The listing also includes some renders of the new phone that hint at similarities with the Oppo A53 2020 that was launched in India in August. In terms of specifications, the Oppo A53s features a 6.5-inch 90Hz display, triple rear cameras with a 13-megapixel primary sensor, 128GB of onboard storage, and a 5,000mAh battery with 18W fast charging support.

Furthermore, it has 8.4mm of thickness and 186 grams of weight.The listed specifications of the Oppo A53s are also identical to those of the existing Oppo A53.
