The contest is simple: download a theme from Huawei's Theme application that reminds you of summer, apply it, and post a screenshot of it under the Facebook post on their page, here. The contest runs from the 2nd of August until the 16th of August, with the rules available here (please read them before participating). Huawei describes it this way:
"Download your favourite Summer Theme from Huawei Themes (landscapes, city views, waterfalls etc.) that inspires you and fits to your summer mood!"
Keep in mind you must live in one of the countries mentioned, as winners will have to provide their contact details, including their name, address, Huawei ID and phone number to claim the prize if they win. Yes, it's in the rules, so make sure to read them.
Winners will be selected by Aspiegel and contacted by the company directly through Facebook. The prize pool of 1000 Huawei Points will be divided amongst the selected winners.
For those who might not know what Huawei Points are, in short, it's a digital currency that can be used to make purchases on Huawei's applications such as Themes, Cloud Storage, AppGallery, Video, etc. We've extensively covered Huawei Points here, as well as here. In Spain and Italy, Huawei Video functions in a similar way to Netflix and other streaming services, with a monthly subscription of 4.99€, which can be paid with Huawei Points.
