This is one company that has tried very hard to break the stereotype of Chinese mobile by launching premium quality mobile phones.
I personally own an One Plus 3, which jas been an absolute pleasure to use. It boasts of an 6 GB RAM for all the multi taskers also can expand the memory till 128 GB which quite adequate for the movie buffs among the lot. It also boasts of a 5.5 inch screen for that wide angle viewing( although I would prefer a phone with a screen size between 4.7 to 5.2 inch) .
With the butter fingers that I have, must have dropped it couple of times butvthe phone has been very forgiving and works without any issue as well.
The software is also quite stable and works very well without any lag. And the icing on the cake would be the Dash charger which charges the mobile to full capacity with 30-35 minutes of charge-time.
By far, the best phone I have owned. Will highly recommend ot to anyone who's budget wouly be in and around 28000 INR.
