YOUR ANDROID PHONE IS SLOW BECAUSE OF A DEFAULT SETTING.
Not old hardware.
Most people buy a new phone before they ever find this:
Takes 90 SECONDS TO FIX. Here is exactly how ⤵️
I have been using this trick since 2012 on my first smartphone.
It made a single-core budget phone feel noticeably faster.
It still works on every Android in 2026. Most people have no idea it exists.
Here is what is actually happening.
Every time you open an app, switch screens, or tap a button your phone plays a small animation.
By default that animation runs at 1x speed. Around 300 milliseconds per transition.
That wait adds up every single time you use your phone.
There are three settings buried inside Developer Options that control this:
↳ Window Animation Scale
↳ Transition Animation Scale
↳ Animator Duration Scale
Set all three to 0.5x and every animation on your phone runs in 150 milliseconds instead of 300.
Your phone does not get faster. It just stops making you wait.
Step 1: Unlock Developer Options
Go to Settings > About Phone > Software Information
Find "Build Number" and tap it 7 times in a row
You will see a message that says "You are now a developer"
Do not worry. This is just a hidden settings menu. Nothing breaks.
Step 2: Find the animation settings
Go back to your main Settings page
Look for "Developer Options" (on some phones it is under Additional Settings)
Use the search bar if you cannot find it quickly
Step 3: Update all three animation scales
In Developer Options, search for “Animation scale.”
You’ll see three animation settings—open each one and set it to 0.5x.
That’s it. You’re done.
Your phone can feel twice as snappy, no purchases, no downloads.
Want it even faster? Set all three animation scales to 0x and the animations vanish entirely.
Some people love the instant feel. Others find it a bit jarring. Start with 0.5x first.
What Android version are you on? I’m curious how well this works on older phones.
