5 years oldVinika Ayemi (Jun 26, 2023) on Gadgets 360 RecommendsBelieve it or not, I purchased J7 Duo in the month of May, 2018 and the only thing i changed is its screen for once. I use screen guard and phone cover too and its still as smooth as i used back then. I believe with care, things last longer. Just wanted people to know that there is a happy customer of J7 Duo here 😁. I would be glad to use it with care so that Samsung company buy back my phone as a monument for its industry 🤣😂.Is this review helpful?
