YouTube has always been the go-to place for users to seek out videos on pretty much anything, making it one of the most visited places on the internet for quite some time. As part of Google's list of services it receives occasional and consistent updates that sometimes introduce new features and/or an improved user experience, and late last year it ended up going through a mobile design revamp with a completely new UI. This time around Google is changing at least one thing visually although the app will still look much the same as it did prior to this update being sent out.
The focus for the update this week with the YouTube app on Android is centered around bringing an improved home page experience to users, and will introduce larger thumbnails for the videos that show up on a user's Home list. Currently, the home page shows a few smaller thumbnails that allow for more to be displayed on screen, but the new larger thumbnails will make it so that each image for a video is spread across the display the width-wise with the video's title and view/posting date information being listed below it as opposed to sitting beside it.
As with all application updates, it won't immediately be available to every single user today and will likely take the rest of the week to spread. If you have auto-update for applications turned off you can go into the Play Store and navigate to the "my apps" section to see if the update is live. Beyond the larger and easier to see thumbnails for videos, YouTube will also look to improve the recommended content by curating the recommendations using machine learning technology. Using deep neural networks YouTube will analyze the watch history and the patterns that crop up from video searches for each and every user to give them a more personalized list of results, which should end up helping them have a better experience within the app. This also means less results showing up once a user opens the YouTube app as content will follow more of a quality over quantity mentality.
