Hi, guys basically xiaomi mobile company was gadget company. It started the production of 4g volte MI mobiles recently. And among all the 4g volte MI mobiles, MI 3S prime is the best deal. It provide long lasting battery backup of 2Days because am using MI 3S prime itself. 1. Battery backup is 2 days as it contains 3000mAH power action as observed. And now if I consider camera option, it is given as 13MP back and 5MP front camera, but rear or back camera is little bit less quality in clarity.2. Camera may be little adjustable in quality, but selfie is superb for the given 9, 000/- rupees. But it is OK.Now for considering the screen resolution, it is smooth for wiping on the screen, and 5 display make mobile smart and small in size. 3. Little HD display, with 5 inch. And now coming to the finger print sensor, here finger print makes a mobile look little stylish, but sometimes due to the sweat in our fingures it does not works. 4. We have to compromise in the fingerprint action, but its good somehow. And now comes to speakers, as we know speakers are given at backside of the mobile, and hence first of all sound will be less, and upon this the speaker’s quality are not good, sound produced will be less compared to other MI Mobiles. 5. Loud speakers are not very effective. And now comes to the internal storage options, it provide 32GB of internal storage, but the usable storage is adding 23 to 25 GB only. Because other 7 to 8 GB are used for functioning purpose of thr mobile software. 6. Internal storage is 25GB.And now comes to the RAM, it provide 3GB capacity but 1.5GB of capacity is only available, this is the major demerit as observed. 7. Only freely available RAM is 1.5GB. And now, the main thing is features of the phone.1. It will be provided with octcore processor and 1.40gHZ clock pulse, but don’t worry.2. It provide dual storage and dial apps options to gain double fb, whatsapp etc. Smart option3. It provide 6.0 above android versions for better style android.4. It provide inbuilt app lock and security functional apps, so enjoy the security.5. Mainly it is stylish and it is gaining the most winning brand name.Thank you. And if you want to buy the MI Mobiles, buyMI 3S PRIME.THANK YOU.
