#1 Enable Closed-Captioning on Your Devices

The first thing I want you to do is to enable closed-captioning on your streaming devices. 

Most of the time, streaming services are configured to ignore our device’s settings. But in certain cases, this may not be possible. Having them set up the wrong way could explain why Prime Video’s subtitles are out of sync. 

If you suspect this to be the reason why you’re having these issues, go to your device’s settings and enable this function. 


For iOS devices:

  1. Go to “Settings”

  1. Scroll down, and tap on Accessibility

  1. Tap on “Subtitles & Captioning”

  1. Enable “Closed Captions + SDH”

For Android devices:

  1. Go to “Settings”
  1. Select Accessibility>Caption preferences
  1. Select “Show captions”

To enable closed captions on other streaming devices, I’d recommend going on Google and searching for “How to enable Closed Captions on <Your Device’s Name Goes Here>”. You should be able to find several detailed instructions for your particular case. 

#2 Disable Your VPN

VPNs are simply amazing. 

Not only do they give us secure browsing, but also open up a world of international content we can enjoy. There’s really a lot to love and very little to complain about!

…which makes it a real shame that streaming companies hate them. 

In fact, many of them, like Disney Plus, HBO Max, Prime Video, Hulu, Netflix, and many more have made this very clear. Some have even gotten to the point of blocking subscribers who use virtual private networks. 

And while I don’t agree with these actions, I can understand them. 

You see, some of the content on these streaming platforms is only licensed to be played in certain countries and regions. Since VPNs allow people from outside these areas of the world to access said content, streaming companies have to take action. 

It’s either that or facing legal issues. 

If you can’t live without using a VPN while streaming Prime Video, I’d recommend getting a premium subscription with a company that has obfuscated servers.

These will make it much harder for Prime Video to detect your VPN traffic, reducing your chances of being blocked.

Solution: If you want to be 100% certain that your current VPN is to blame for this situation, try disabling it for a while. 

If Prime Video’s subtitles are no longer out of sync, there’s your answer. 

#3 Check Your Connection

While it’s true that Internet service drops have gone down a lot in the last few years, it’s not safe to say they don’t happen anymore. 

In most cases, this is easily noticeable, as you won’t be able to browse the web. But sometimes, you may only have a weak signal. This would allow you to keep browsing lightly or chatting while also having Prime Video’s subtitles be out of sync. 

That’s when diagnosing a bad connection gets tricky.

If you think about it, though, it makes a lot of sense. Streaming your favorite content online is much harder on your home network than texting your friends about your day. 

Prime Video needs an Internet signal of at least 5 Mbps to stream in Full HD resolution (1080p), and an incredible 25 Mbps for 4K (2160p).

Solution: Do you have a large family, or is it just you at home? I ask you this because the answer will determine the Internet plan you should have.

If it’s the former, I recommend that your plan is at least 5-6 times faster than Prime Video’s requirements. For example, if you want to stream in Full HD resolution, you should have a connection of 25-30 Mbps. 

If it’s the latter, you could get away with something 2-3 times faster than what the platform needs. 

Assuming that your current plan is already fast enough, you might want to try giving your provider a call and asking if they’re having issues. If they tell you everything’s fine on their end, you should try resetting your modem and see if that works. 

Doing so is really simple, you just have to follow these steps:

  1. Without unplugging the modem, turn it around, so you can see the back of the unit
  1. Locate the reset button (more often than not, it’s not a button, but a small hole with a “Reset” label on it)
  1. Use a paper clip or a thin toothpick to press down on the actual button inside this hole. Hold it down until all the lights at the front of the unit turn on, and then turn off
  1. For a brief moment, all lights on the modem will be off, that’s your cue to stop holding down the reset button
  1. Wait about 5 minutes or so and try streaming Prime Video. If your connection was to blame, your subtitles should now be back in sync. 

If this solution didn’t work either, don’t lose hope, we still have a lot of ground to cover. Keep reading to discover more fixes you can try!

#4 Check Prime Video’s Servers

Moving on, let’s make sure the platform’s servers are doing ok.

As you may know, these are responsible for storing important information and providing millions of Prime Video subscribers with quality service. 

Given how important they are to its everyday operations, that company has put a lot of work into making them as resistant as possible. And while I’m not saying they’re as fragile as glass, I’d be lying if I told you they can’t ever fail. 

Things that seem unimportant, like a coding bug, a broken hard drive, or even minor hacking can affect the platform’s performance and have a negative impact on its features. 

The best way to tell if this is happening is by looking out for login difficulties, issues verifying your subscription, or out-of-sync subtitles. Sometimes, you may also get random flickering

Solution: If you suspect this to be the source of the problem, I’d recommend checking the real-time status of the platform’s servers. 

Here’s how to do that:

  1. Open Google, and type “Is Prime Video Down?”, then hit Enter to search your query
  1. Locate “Downdetector” on the search results, and click on it (or simply click on this link:
How to check if Prime Video's servers are down on Downdetector
Make sure you’re entering the official Downdetector website
  1. Once you’ve entered the webpage, you’ll see a bunch of data, and a large graph
Downdetector report graph
The taller the spikes, the more likely you are to be having problems

Sadly, if the servers are currently failing, your hands are tied. 

But I wouldn’t worry too much about it. These events don’t last very long. You should expect everything to be back to normal within 2-24 hours. 

#5 Update Prime Video

I know how keeping your apps outdated doesn’t sound like a big deal. And while it’s not a federal crime, it can cause your streaming services to act strange, restart randomly or fail to connect to your home network, 

You see, with every new release, app developers try to keep as much backward compatibility as they can, but it’s not always possible. Using an older version of the platform’s software on a fully updated streaming device could explain why Prime Video’s subtitles are out of sync. 

Normally this shouldn’t be your concern, as automatic updating takes care of everything. But sometimes network interruptions or strict device privacy settings can get in the way. 

In that case, you’ll have to manually install the latest version of Prime Video to your devices. 

Solution: There are hundreds of streaming devices out there. If I were to guide you through the process of updating Prime Video within each one, we’d be here all day. 

And while I don’t mind it, I’m sure you’ve got a very busy schedule!

Instead, I’d recommend going to Google and searching for “How to update apps on <Your Device’s Make And Model Go Here>”. 

To give you a general idea of the process, here’s how to do it on iOS and Android devices, as well as on a Roku system. 

For iOS devices:

  1. Open “App Store”
  1. Locate your profile button in the upper right corner of the screen, and tap on it
  1. Find the “Update All” button. This should Update Prime Video if there’s a newer version available
This would be a good time to update all your pending apps

For Android devices:

  1. Go to Play Store and click on your profile, located in the upper-right corner of your screen
  1. Select “Manage apps & device”
  1. If you just want to update Prime Video, select it and update it individually
  1. If you want to update all pending apps, select “Update All”
  1. Wait for the updating process to be completed

You may be prompted with a notification asking for your permission to proceed with the updates. If so, simply accept and be patient. 

For Roku:

  1. Press the “Home” button on your remote
  1. Move over to the right side of your screen, where your app list is
  1. Look for Prime Video
  1. Hover above it and then press the Star “*” button on your remote
  1. Find “Check for updates” on the list, and select it
  1. The system will check for newer versions of the app. Should it find any, accept the installation
  1. Wait for the process to be completed, and you’ll get a message saying “Prime Video is up to date”

#6 Try a Different Show

Maybe the answer is much simpler than you think.

You may not know this, but every piece of content within Prime Video has its own ID and space on the company’s servers. This is why sometimes you might have trouble streaming a specific title, but be able to enjoy another uninterrupted. 

By keeping its content organized this way, the platform can prevent a single issue from becoming a general failure. 

This is normally a good safety measure, but it could also trick you into thinking that the problem you’re having is bigger than it actually is!

Solution: Try switching between different shows and movies and see what happens. 

If subtitles are not out of sync on the rest of the platform’s content, chances are the title you were trying to watch is the only one having issues. 

In that case, all you can do is wait until things go back to normal. 

#7 Clear Your Cache & Cookies

If you have no idea what these are, that’s ok! Most people are in the same boat. 

But now that you’re reading this, I’d like to take this opportunity and shed some light on the concepts, starting with the cache. 

This is where your favorite apps store important information. In it, you’re likely to find preset configurations, user preferences, audio, and video. By keeping this data handy, Prime Video can load much quicker when launched. 

Cookies, on the other hand, are tools used to make your browsing more efficient and help targeted ads be more accurate. They’re the reason why you’re suddenly bombarded on social media with ads for cupcake molds right after looking up a recipe for pastries. 

For the most part, leaving them both alone does more good than harm. But in certain cases, this could be the reason why Prime Video’s subtitles are out of sync. 

In that scenario, your best bet will be to clear them. 

Solution: Deleting your cookies and cache is really simple in most major browsers and operating systems out there. For this example, I’ll show you how to do it on Google Chrome and an Android device. 

On Google Chrome:

  1. Open the browser
  1. Click the Menu button (the three dots in the upper right corner of the screen). Select “More Tools” > Choose “Clear browsing data”
Clear browsing data on Google Chrome
  1. Select “All time” when prompted with a window asking the time range you want to delete data for. 
Delete cache and cookies on Google Chrome
If you’ve never deleted your cache and cookies, this process may take a while
  1. Make sure “Cookies and other site data” is ticked. 

On Android devices:

  1. On your device, go to “Settings”
  1. Select “Apps”
  1. From the new menu, select “Apps” again
  1. Find Prime Video and select it
  1. Find “Storage” on the menu
  1. Select “Clear Cache” from the available options 

#8 Uninstall Prime Video

Finally, let’s try something different. 

If none of the solutions above have worked, we might need to be a little more aggressive. 

In most cases, closing and relaunching the Prime Video app should get rid of most problems. But sometimes things are more complicated. 

Now and then, a corrupted file or bug might not go away until the app is fully removed from your streaming devices. By uninstalling and reinstalling Prime Video, you’re giving the service a fresh start.

And the best part is that this fix works for about 90% of all technical difficulties out there, so don’t be afraid to try it out!

Solution: In case you’ve never uninstalled an app on your devices, here’s how to do it on a Roku to paint you a picture:

  1. Press the “Home” button on your controller
  1. Move over to your channel list on the right side of your screen
  1. Find Prime Video
  1. Hover above it and press the Star “*” button
  1. From the dropdown menu select “Remove Channel”
  1. Wait for the process to be completed


Having Prime Video’s subtitles play out of sync can be very annoying. Especially when you consider that you’re paying a monthly subscription. The least you’d expect for your money is a decent service. 

What a disaster!

Luckily, as I hope you’ve learned in this piece, addressing most of the causes behind this situation is very simple. Most of the time, simple actions, like keeping your app fully updated, and using the right VPN, should do the trick.
