There is a way to watch YouTube without ads fully legally. All you need to do is buy a temporary YouTube Premium subscription, which also gives you more options like downloading content to your phones to play them when you are not connected to the Internet. An interesting promotion is provided to customers by the well-known manufacturer Samsung, who will provide limited access to YouTube Premium subscriptions to some of its users.
The promotion applies to customers who bought and activated a new Samsung Galaxy phone between 14th of February 2020 and 5th of March 2021. Purchases made outside this period will not be included in this campaign. Length of period during which users will be able to use YouTube Premium for free depends on the phone model they purchased. Customers who purchased the Galaxy Z Flip, Galaxy Fold or any model from the Galaxy S20 series will receive 4 months of free access to YouTube Premium. Holders of other Galaxy phones will be able to use YouTube Premium for 2 months for free. To activate the service, enter your YouTube account settings and click "Try for free" in the "Become a YouTube Premium member" section.
