If your Android is starting to lag so badly you’re tempted to throw it against a wall, hold off on spending hundreds of dollars on a new one. Let’s be brutally honest: your phone isn’t dying, it’s just suffocating under all the digital junk you’ve been hoarding.

Those constant freezes and apps that take forever to open aren’t a death sentence. Your phone is just bogged down by all the apps you never use, the countless old files you’ve forgotten, and all the mystery processes draining your battery in the background. And while you’re at it, you should probably just wipe down the physical phone itself-it’s almost certainly gross.

So, don’t give up on it yet. A few simple fixes are all it takes to clear out the clutter, boost its speed, and make your phone feel a whole lot less ancient.

Delete all of your forgotten apps

Take a few minutes to go through your home screen or app drawer and delete any and all apps you no longer use. Not only do those apps take up precious storage, but they also potentially have access to the personal information or permissions you approved when the app was first launched. 

How you go about deleting an app can vary based on who makes your device, but I covered all the bases in this post. Give it a read if you don’t see an uninstall option after long-pressing on the app’s icon. 

Eliminate old files to free up storage

After removing any old apps, free up more storage by going through the files saved on your Android phone. It’s far too easy to forget about all of the files you’ve randomly downloaded — like the takeout menu of the new place down the road or a GIF a friend sent. And those files add up. The quickest and easiest way to manage your phone’s storage is to use the Files app that comes preinstalled. 

Actually, some phones use a variation of that same app. On Samsung, for example, it’s called My Files. On the Pixel lineup, it’s just Files. On the OnePlus 10 Pro, it’s File Manager — you get the point. 

I recommend opening the app drawer on your phone and reaching for «files.» Odds are that will reveal whatever your phone-maker calls the app. 

Start with checking the Downloads folder, where you can either delete the files you no longer want or move them somewhere like Google Drive.

Most file apps will also reveal any large files that are saved on your device. For instance, the OnePlus 10 Pro’s File Manager app has a dedicated section in the app for files that are taking up a lot of space.

Tweak home screen settings for a new look

One of the best parts of Android is how much you can customize the entire look of your phone. From installing app icon packs to completely replacing the launcher your phone uses, there are plenty of options to personalize your phone. 

While you can definitely jump into tweaking launchers and installing app icons, start by digging into the home screen settings your phone already provides. I do this once in a while, and it’s surprising how subtle tweaks to aspects like app layout can make it feel like an entirely new phone. 

Long-press on a blank area of your home screen, then select Home settings (or some variation of that). That will open the options for your home screen, where you can customize various settings. 

Settings like the size of the app grid. It may seem like a small change to go from a grid of 4×5 apps to 5×5, but that extra column can make a big difference (the same can be said about shrinking the grid). 

This is also where you’ll find settings for things like swiping down on the home screen to view notifications instead of having to swipe from the top of the screen. 

Go through the respective settings your phone has and experiment with your home screen setup. 

Optimize your device settings

Speaking of settings, now is a good time to go through and change any settings that have been annoying you. I have a roundup of settings you’ll want to change and customize on any Android phone to get the most out of it. 

For example, turning on dark mode not only makes the app look better, but it also saves battery life. And yes, I even show you how to stop app icons from automatically appearing on your home screen. 

Customize your privacy options

Before you take a break, do yourself and your Android phone one last favor — double-check your privacy settings.

Open the Settings app then tap Privacy > Permissions Manager. Go through each category to see which apps currently have access to which treasure trove of your personal data. Find an app you don’t want to have access to your location? Turn it off. The same goes for contacts, calendar or camera. 

It doesn’t take long to go through each section, and even if it did, it’s well worth the effort.
