U8 Bluetooth Smart Watch – A Quick Review

u8I got this smart watch from my lil’ sis for N4,500.00, after driving a hard bargain. I am sure she got it for about $10 on amazon, less tax and shipping costs. With exchange rate at about N300 to US$1, not sure she would be making much profit on it.

This would be my first Smart Watch. The closest I had to this was my Adidas ADP6097 Digital Watch whose strap got cut a few weeks back.

This watch is a steal for the price. It might be a little difficult to wrap around your head the word “Smart Watch” and “$10” being used in a single sentence but, believe me, it is for real. Of course you will not expect to find qualities near that of the Apple range of Smart Watches.

Unboxing this device was in no way eventful. The accessories were very sparse – only a single USB cord (Note: No power adapter) was included in the box and a forgettable “Chinese Type” manual.

A quick run down of the Pros and Cons of this watch will give you a better insight to what this watch can or can not do;


  • Control your Phone camera from your watch (only for android phone)
  • Stream music from your device
  • Fast charging. About 20 minutes, or less.
  • View Contacts. Make and receive phone calls.
  • Receive phone notifications
  • Sync your phonebook and call log
  • Anti lost feature – Alerts you when your phone disconnects from your phone
  • Barometer, Altimeter and Pedometer


  • Out of the box, the menu of the watch was in Chinese characters. I had to grope in the dark to change it to English.
  • Does not support remote camera functions and notifications on Apple iOS devices
  • Does not have inbuilt SIM slot.
  • The rubber flap that covers the charging port is flimsy

The beauty of a device is in its ability to be hacked for enhanced functionalities. The U8 Smart Watch does not disappoint.

How To Block Ads In Android Without Rooting

One common excuse people give for rooting their android devices is to block annoying ads from popping up on their devices.

This indeed is a compelling reason as mobile ads, at best, can be;

  1. intrusive and distractive
  2. ruinously expensive as it burdens device hardware resources and also drain internet data.

Popular ad blocking apps like adaway and Netspector are only available for rooted devices.

For non-rooted apps, there are a few apps available on Google Play. They work, basically, by creating a mock virtual private network (VPN) for you and you alone and then connects your device to it. What this means is that all traffic you have coming in is through the app, and it protects all your data on its way out.

Notable among these apps is Lostnet NoRoot Firewall. WIth LostNet NoRoot Firewall you will be able

  • to block Internet access for any app. Let LostNet Firewall provide full Internet access to an app or access only in Wi-Fi networks or no access at all.
  • to block access to any country/region for all your apps. Use LostNet Firewall to prevent your apps from connecting to the countries you don’t trust or don’t want to deal with.
  • to block background activities of your apps. Surprisingly a lot of apps generate traffic while they are in background mode. LostNet Firewall may decrease your data consumption by blocking these apps.
