Design-wise, both the devices come in a glass front and plastic back body. On the front, both devices feature an AMOLED display but the Samsung Galaxy A51 has a punched hole display which gives it a more premium look as compared to the teardrop notch of the Oppo F15. The devices feature a plastic back which is nice from a durability perspective but leaves much to be desired at this price point. Lastly, both devices feature an on-screen under-display fingerprint sensor for biometric authentication. So, both the devices are equally matched in the design segment.
Talking about the display, once again both devices are equipped with AMOLED displays. The Galaxy A51 features a 6.5 inches Super AMOLED display with a resolution of 1080 x 2400 pixels(~405 PPI density) and a 20:9 aspect ratio. Similarly, the Oppo F15 features a 6.4 inches AMOLED display with a resolution of 1080 x 2400 pixels(~408 PPI density) and a 400 nits peak brightness advertised. So, display-wise as well, both devices are comparable in this segment as well.
Speaking of cameras, the Galaxy A51 comes with a 48MP f/2.0 main camera coupled 12MP ultrawide and a 5MP macro cameras. Whereas the Oppo F15 comes with 48 MP, f/1.8 main camera, an 8 MP, f/2.3 ultra-wide camera coupled with a 2MP B/W sensor.
So, the primary camera of the Oppo F15 with a larger f/1.8 aperture has an edge on paper but the Galaxy A51 fights back with its better ultrawide camera at 12MP and an additional dedicated 5MP macro camera which is absent on Oppo F15.
On the front, the Oppo F15 has a 16MP f/2.0 shooter whereas the Galaxy A51 has a 32Mp f/2.2 shooter. Resolution wise, Galaxy A51 has an edge over Oppo F15 but larger aperture on Oppo F15 will offer you slightly brighter selfies in low lights. So overall optics wise, both the Galaxy A51 and Oppo F15 has its own strengths and weaknesses.
Specs and Software:
On the inside, the Galaxy A51 packs Exynos 9611 (10nm), Octa-core (4×2.3 GHz Cortex-A73 & 4×1.7 GHz Cortex-A53) CPU and a Mali-G72 MP3 GPU coupled with 6GB of RAM and 128GB of UFS 2.0 storage. On the other hand, the Oppo F15 packs a Mediatek Helio P70 (12nm), Octa-core (4×2.1 GHz Cortex-A73 & 4×2.0 GHz Cortex-A53) CPU and Mali-G72 MP3 GPU and an 8GB RAM with 128 GB UFS 2.1 internal storage.
So specs-wise, the Galaxy A51 comes with a slightly faster & power-efficient CPU compared to Oppo F15. But you will not find a big difference between Galaxy A51 and Oppo F15 when it comes to gaming. Likewise, Oppo F15 comes with slightly faster storage and extra 2GB RAM, which should help loading apps and games a little faster and should make the device run smoothly for a long time.
Taking a look at the battery, both devices are powered by 4000mAh battery but the Oppo supports 20W fast charging whereas the Galaxy A51 supports only 15W charging.
Speaking of the software, the Galaxy A51 runs on Android 10.0 with One UI 2.0 on top of it. On the other hand, the Oppo F15 with ColorOS 6.1 on top of it. So, software-wise, the Galaxy A51 comes with the latest version of Android OS right out of the box but Oppo F15 will get Android v10 update sooner or later.
Taking a look at the pricing, the Oppo F15 costs Rs. 39,999/- for the 8GB+128GB variant whereas the Galaxy A51 will cost you Rs. 38,399/- for the 6GB+128GB variant. So, price-wise, Galaxy A51 is slightly affordable compared to Oppo F15 in Nepal.
All-in-all both devices should give you a somewhat similar performance. So in the end, choices really depend on which brand you prefer. But if you want the best smartphone under 40k budget in Nepal, then we’ll suggest you read our Best smartphone under 40000 in Nepal post.
