Mobile phone is something nobody can love without. Almost everyone needs a mobile phone. There are some point which needs attention before buying a mobile phone.
1) Brand - you should buy the mobile phone off a trusted brand like Apple, Samsung, Motorola, Mi. Because trusted brands will ensure that you get costumer service. If you face any problem with the phone you can go to their service centre and get the problem solved.
2) Display size - Mobile comes in various screen sizes sizes. 4 inch, 4.5 inch, 5, 5.5 inch and bigger than also. You need see what is suits you better. Apart from size you should see the resolution of the display. Resolution more than 720p is good less than that is not. Try getting 1080p resolution, they are best because they will consume less battery and will still give you the best viewing experience.
Also look what protection is on the display. Buy gorilla glass display.
3) Connectivity - 4G has become common and important. Jio only runs on 4G. You will get the best internet speed currently at 4G. So buy a phone which is 4G compatible. If VoLte is supported then it is even better.
4) Camera - 80% of people take photos from the phones camera only. In most of the occasions. That’s why you need a good camera so that you can capture the moment you want too. Buy phone which has at least 12 MP camera. The aperture size should ve between 1.7 -2.2 . Bigger aperture means better photos. Also see if the phone’s camera has any stabilization or not. Optical or electronic stabilization makes videos taken less shaky. So buy the phone which has stabilization on camera.
5) processors - But the phone which had snapdragon processors, they are the best. Good processor runs your phone smoothly.
6) miscellaneous - See if the phone had IR blaster. It allows you to control tv, AC, through your phone only.
