I am using this phone from the last 2 week. The sound quality isn’t that good but Its ok. The design of this phone is old just like other xiaomi redmi phones. Camera quality of this phone quit good. 13mp rear and 5mp front . Supports dual 4g sim. Redmi 4a has a 1.4 ghz processor and 5 inch disply which make phone better. It feel good to when I hold it in my hand grip is nice. The poor thing of this phone has heating problem. Redmi 4a good choice for budget phone now in market.
