So here’s my advice for you, before buying a phone make sure you’ve checked for its specifications to ensure they actually comply with what am about to uncover below.
1. Screen Size/Resolution
This is the size of the device’s screen. It is most likely measured in inches or cm/mm. Are you a fan of large screen phone, then you should be looking at a device in the range or larger than 5.5/6.0 Inches.
2. Android OS
Make sure it’s running on the most recent version of Android OS. As at the time of this writing, Android 6.0 (Marshmallow) should be your minimum target though Lollipop ain’t bad either, just make sure it has OTA update to receive latest Android updates. (Update; Nougat is available, so look forward to a device with this new OS..it’s called Android N 7.0)
