The Samsung Galaxy A30 is a mid-range Android smartphone developed, manufactured and marketed by Samsung Electronics. Running on the Android 9.0 "Pie" software, the A30 was unveiled on February 25, 2019 alongside the Samsung Galaxy A10 and Samsung Galaxy A50 at the Mobile World Congress. It was released a month later on March 2, 2019. The A30 was praised by critics for its display and user interface. However, criticism was aimed at the phone's performance, battery life and camera.
Its "s" variant was unveiled on August 22, 2019, which features an upgraded camera setup but with a downgraded screen resolution.
Both devices feature a plastic back, plastic frame, and glass front (Corning Gorilla Glass 3 for the A30 only). The A30 variant sold in Japan also carries IPX5, IPX8, and IP6X ratings, marking the partial return of waterproof certification on the Galaxy A series, a feature not seen since the Galaxy A8 (2018).
The A30 have a 6.4" FHD+ (2340 x 1080) 60 Hz Super AMOLED Infinity-U display, with an 19.5:9 aspect ratio. The A30s, however, features the same screen size and display type as the A30, though at a lower resolution (HD+, 1560 x 720) and with an Infinity-V notch.
Both devices feature the same 4000mAh battery with 15W Fast Charging support. The A30 variant sold in Japan features a slightly lower 3900mAh battery capacity, but with the same 15W Fast Charging support.
Both variants use the Samsung Exynos 7904 octa-core SoC, with RAM options of either 3 or 4 GB, and storage options ranging from 32 GB to 128 GB (the 128 GB variant is exclusive to the Galaxy A30s only). Both variants also use eMMC 5.1 for its storage type. It also support expandable storage via microSD card up to 512 GB.
The A30 has a dual-rear camera setup (similar to the Galaxy A40) consisting of a 16 MP (f/1.7) wide camera and an 5 MP (f/2.2) ultra-wide camera; it also has a 16 MP (f/2.0) front camera. The A30 model sold in Japan retains the same ultra-wide camera but features downgraded specifications for its main wide camera (13 MP, f/1.9) and front camera (8 MP).
The A30s, on the other hand, has a triple-camera setup (similar to the Galaxy A50s) consisting of a 25 MP (f/1.7) wide camera, an 8 MP (f/2.2) ultra-wide camera, and a 5 MP depth camera; it also uses the same front camera as the A30.
All variants have Android 9.0 Pie and One UI 1.1 pre-installed. It was eligible for 2 OS upgrades and 4 years of security updates.
Both Deepak Rajawat of smartprix and Sanket Vijayasarathy of India Today praised the Galaxy A30's display, software and battery life, but criticized the phone's chipset due to performance issues and the "average" quality camera. Tom Bedford and Matt Swider of TechRadar also complimented the vibrant screen of the A30. However, the reviewers found the phone difficult to handle due to its large size. Writing a review for 91mobiles, Shekhar Thakhan praised the phone's AMOLED display, One UI interface and battery life as well. In contrast, the back of the phone was noted by the reviewer as a "fingerprint magnet".
