Samsung J7 Duo Review
Welcome to the review on the Samsung J7 Duo version review. We bought the J7 Duo as we needed a new dual SIM smartphone at a reasonable price and with decent performance and hardware specifications. The Samsung J7 Duo is a European and Asian/Indian marketed phone where many need multiple SIMs for travelling in different countries and for many who use it as a personal and work phone.
In terms of construction the J7 Duo is a slim phone made of plastic. The back comes off so you can insert the SIM card and the memory card. The rear cover is highly integrated so you wouldn't notice it, hence it is a good design. The rear cover is typical Samsung fashion is slim and tight in the same vein as the benchmark Note but not as premium in feel. The screen is a glass one that makes the J7 Duo feel better than it should. Overall is very good for the price.
In terms of hardware the J7 Duo is packed with the latest tech again beyond the price tag. That includes a Super AMOLED screen, an Octa-core 2.2 Mhz CPU, 32 GIG memory, 4G or LTE, finger print reader and an FM radio amongst it's hardware features. Note that specification often say its has 4Gig Ram but our version only had 3 Gigs which didn't seem to effect performance. For a brand like Samsung to have this sort of specifications is impressive.
In terms of use the J7 Duo is impressive. It's fast and smooth despite some additional Samsung and Google apps installed as standard. Loading apps is fast and equal to any iPhone up to the 8. The finger reader is the fastest we've used is worth noting. The camera takes good pictures likewise video so we have no complaints. We like that you can place a widget on the home screen that allows you optimise the performance of the phone which it's competitors especially the iPhone really needs as the lasses iOS really lags in this area now. Yes the comparable iPhone 6S slows down notably more so that the J7 Duo!
In conclusion the Samsung J7 Duo is definitely one of the best dual SIM Android OS smart phones you can buy in 2018 and 2019. (Hence we bought one) The J7 Duo sells for under 200 Euro and estimated mid $300 AUD there's little competition even from the Chinese brands. Note that getting a J7 Duo is difficult in many countries so if you happen to be Singapore, Malaysia or India see if you pick one up!
