As I mentioned its a double phone .its really a dual phone.Every thing you can get in this phone are of two numbers.Except Memory, RAM and SIM.Eg, You can access two phones in one handset, this all due to the User Interface MUI-8.
You can separate this phone to two phone by your choice and that also to purely secure way.If you want to store your personal Data, Facebook account, Whatsaap, /Messenger, Mail and any other application secure then its the best phone to go for.
Don’t need third party application to secure your data.Thanks to MI giving a feature "Dual Space".Here you can separate you phone to two phones.Public and Personal.Though your phone is open for all and every one knew your password to unlock and access your social sites also, still no one can know another account is running in the same phone which can be unlock with different password/different finger print.
Pros:
1-User interface -Best one, better than Android and lots of customization available.
2-Processor-Top rated it will surely meet your expectation.
3-RAM-You will get sufficient available RAM after instaling your essential aaps and games.
4-Built quality is satisfactory .
5-Storage 32 gb version is sufficient for normal user. You may get 25 gb available .
CONS:
1- I am really dissipointed with its camera. Both Front and Rear camera needs improvement.
2-Hybrid SIM slot will be another drawback, you cant use Memorycard if you use dual sim.
You hv to sacrify one sim if you need more srorage.
3-Though built quality is very good but design will dissapoint a bit. Should be little thinner compare to other phone in same range. Also very sleepy when hand .
COCLUSION-The phone is value for money if we compare from price angle but needs improvement in quality and design point.but going for it will not dissipoint you. Feature and processing will kill others in same range.
