Two days from now (on June 4), the Samsung Galaxy A31 will launch in India, and will be exclusive to Flipkart. For now, the teaser page of retailers only contains a Notify me button along with some highlights of specs.
It is expected the price will be around INR 23,000 (speculated). This will be quite a premium over the Galaxy M31, which started at INR 15,000. The two phones have a few things in common, like the Super AMOLED 6.4 “1080p+ display. The A31 however has a fingerprint reader in display, while the M31 has a traditional rear-mounted reader.
Both phones have similarly quad camera setups: wide, ultrawide, macro, and depth. The M31 however has a 64MP main sensor that can capture 4K video, the A31 has a 1080p 48MP camera. The M31 also has a bigger battery, 6,000mAh vs. 5,000mAh, but the A31 is slightly lighter and more compact.
Anyway, the price difference may be due to a different configuration, i.e. we can only see the 6/128 GB version of the Galaxy A31 (but usually an INR 1,000 upgrade goes from 64 GB to 128 GB).
