A month before the premiere in the network appeared fresh details about the smart watch Google Pixel Watch 4. The source of the ?leak? was an insider with the nickname billbil-kun - he published the retail prices of different modifications of the device for the European market.
The company vivo introduced a new line of smartphones Y50, which includes a basic model and a version Y50m 5G. The main characteristics of the devices are the same, including a capacious battery and a protected body, and the difference between them is only in the memory configurations.
The company realme released a 4G-version of the previously presented smartphone Narzo 80 Lite. Distinctive features of the novelty, the price of which is less than $90 in the basic modification, are a rugged body, a screen with higher refresh rate and a capacious battery.
