If you are a business person, windows phone is just the best. I use Nokia Lumia 1520, I bet the performance is better than Blackberry Priv.

1. My fully charged battery will last me for over 30 hours of continuous use for calls, messaging, e mailing, internet surfing amongst others.

2. The speed is just excellent, I have never experienced it hanging.

3. User Interface is also very good. Easy navigation and cool design.

4. I process an average of 10 mails per e mail address daily and I have nineteen (19) different official e mail addresses set up on the device and with optimum performance.

5. The phone has a 21 megapixels high resolution rear camera. Several friends have used my phone as professional cameras because you just wont believe its output and edit capabilities.

6. I use windows 8.1 but planning to upgrade to windows 10. Its just another computer for me.

7. The video playback quality is just like a 3D session and it has an auto projection inbuilt with the phone which allows me to share my screen automatically with a miracast enabled TV/projector.

8. I used to have 193 different apps without any impact on the phone but recently deleted some, left with 147 apps, some which are as heavy as 918MB, yet the phone performs excellently.

9. On security, no virus threats and I have an inbuilt mobile tracker which allows me to read all messages, facebook, whatsapp, calls log with recorded audio conversations, locations, wipe data, lock phone, snap picture and so on remotely, especially when the phone is stolen or missing.

This is just to mention a few but I can go on and on.

Forgot to mention, the time I got the screen broken, I paid N41,000 to fix it. I have used the phone now for over 18 months without a cover or protector and it still looks new because of the anti scratch design.

please where did you change your screen?
