Passage 1
Do you find it difficult to put down your mobile phone?
If yes, you’re not alone. These days, many people are facing the stress in the use of mobile phones. They reach for their mobile phones when they wake up in the morning, and keep checking their social media apps to get the latest updates(更新).
A report from Google shows that 70 percent of people don’t want to spend much time on their phones. This is why Google introduced an app called Dashboard for the new Android operating system(安卓操作系统). This new app includes functions(功能) that help users manage the time. For example, users can see how many times they’ve unlocked their phones, how many times they’ve checked their social media apps, and how much time they spend on each app every day.
Once the users see this information, they’ll be able to make some changes. With the App Timer(计时) function, users can set a time limit for how long they can use each app for every day. After they’ve hit the limit, they won’t be able to use the app until the next day. And with another function, the app gets incoming calls silent when the user puts the phone face down.
If people truly want to make full use of their free time instead of losing hours on their phones, these new functions are just one way of doing that.
After all, who needs to use an app to stop you from using other apps? The easiest answer would be just to use your willpower.
