preface:

    I have been following Leifeng's trial activities for a long time, and almost all of them applied for each trial, but they failed every time! Unexpectedly, I fell in love with Xiao Hei this time, which rekindled the fire in my heart, and kept my passion and enthusiasm in my heart. I worked tirelessly to come to Lei Feng Forum!  

    As a black powder, I can be traced back from the Xiaohei generation. Now I've got 2 generations for free. That's happy. It's hard to say how excited I am. I know that only persistence and perseverance can make me today!

Here, first of all, I would like to thank Lei Feng.com for giving this trial opportunity!

Stop gossiping and start evaluating:

Open the packaging box, and there is a plastic cylindrical box inside. In terms of packaging, the author asked Xiao Hei two Full of expectations

The appearance of Xiao Hei need not be mentioned Pretty cool ; Pure black case , Plus beautiful self mention . Refreshing !

Especially back charging , There is a small magnet at the back, which is paired with the charger to avoid dislocation of the positive and negative poles; Extraordinary customers oriented； It is also waterproof.

I bought Xiaohei myself one generation , In contrast, Xiao Hei 2, Appearance , More man A little, very cool. The biggest feature is that the electronic watch that looks very handsome has finally bid farewell to the appearance of cheap goods. Xiao Hei two The outer screen adopts full fitting coverage mode, and the glass adopts deep strengthening process, so the hardness can reach Mohs hardness seven , compared with Xiaohei one Dai Geng is scratch resistant and can resist scratches of metal products and ordinary glass. The friends who follow this screen must know that the power consumption is very low, which is why Xiaohei two Attainable thirty The battery life of days depends on this low-power screen.

Xiao Hei two There are four A key, basic and black generation, but more fashionable.

Start to use, Bluetooth connection ！！！

It has many functions, including the loss prevention like the first generation.

The newly added running function can be worn when running. I tried it. It has real-time speed matching and real-time step frequency detection and display, which is good. Look at my grades.

It's very practical. I like one. It has pace and pace. It's very practical

accident:

But the good times don't last long. My hands are cheap. When I saw the upgrade of firmware 3.38, I did it. Then, there was no later....

。

in fact, I'm updating to three point eight At that time, the machine was inexplicably unable to upload information to the mobile phone......

It is good to prevent anything from being lost. You can also push information, which means that all health information cannot be uploaded to mobile phones. Each time, the user prompts that it can be upgraded to 3.39, but the update result shows that the version remains unchanged.

I tried to replace the phone after returning to the factory, but it didn't work....

Well, as a watch, he is also very beautiful.....

Summary:

It seems that Xiaohei 2 has made great progress compared with Xiaohei 1, but there is still a long way to go

I'm not in the mood to continue coding. I contacted customer service and didn't know whether it could be resolved
