Samsung Galaxy S21 Problems: 5 Things You Need to Know



Samsung Galaxy S21, Galaxy S21+, Galaxy S21 Ultra, and Galaxy S21 FE users are running into a variety of bugs, performance issues, and software glitches.

The company’s still working to resolve problems that have been around for months and we’ll continue to see new issues emerge as more people buy these phones and as current owners put more mileage on their devices.

In this guide you can learn about the current state of Galaxy S21 problems, potential fixes for these problems, places to find feedback, and what’s next in terms of Android software updates for these phones.

Galaxy S21 Problems

Galaxy S21, Galaxy S21+, Galaxy S21 Ultra, and Galaxy S21 FE users are encountering numerous bugs and performance issues. A lot of these complaints have come from users who recently installed the latest version of Samsung’s Android 12/One UI 4 update.

Galaxy S21 users are reporting abnormal battery drain, installation issues, notification issues, problems with first and third-party apps, UI lag, charging issues, data issues, screen refresh problems, issues with the camera app (the app has crashed numerous times on the Galaxy S21 in our possession), call quality issues, Wi-Fi problems, sound issues, and more.

Again, this list will grow as times goes on as more people buy the Galaxy S21 series and as Samsung pushes out new Android firmware updates to these phones.

Where to Find Feedback About Performance

If you own a Galaxy S21, Galaxy S21+, Galaxy S21 Ultra, or Galaxy S21 FE, or if you’re thinking about buying one of these devices, make sure you keep an eye on feedback about performance from Galaxy 21 users.

There are several places to find feedback about the Galaxy S21 series’ performance on Android 12. We recommend keeping an eye on XDA-Developers, the Galaxy S21 Reddit, and the Android Reddit.

If you live in the United States you’ll also want to keep your eyes on the official AT&TVerizon, and T-Mobile forums if you own a Galaxy S21 model on one of those networks.

We also recommend poking around social media sites like Twitter and YouTube for feedback about the Galaxy S21 series’ current performance.

We’ll also provide you with the latest information about Android updates for the Galaxy S21 so be on the lookout for new information as we cruise through the year.

How to Prepare for Android Software Updates

Samsung and its carrier partners will fix a lot of these lingering issues, but software updates often bring problems of their own so you’ll want to be extremely careful.

When you fire up your Galaxy S21 there’s a chance you’re prompted to download a new version of Android. Again, new updates can cause problems so you’ll want to prepare your device for the move to a new Android build.

There’s no way to predict how a new version of Android firmware will impact your Galaxy S21’s performance. Some of you will see a performance boost, others will run into issues. This is precisely why you should spend some time prepping your phone for the move.

Here’s what we recommend doing before installing Android on your Galaxy S21, Galaxy 21+, Galaxy S21 Ultra, or Galaxy S21 FE:

  • Backup your data.
  • Get familiar with the newest version of Android 12.
  • Have your login information handy.
  • Dig into feedback about the latest updates performance.
  • Cleanup your phone’s storage.
  • Find fixes for potential problems.
  • Check in with IT.
  • Check app reviews and install updates.

Follow these steps and you should be able to avoid major issues.

How to Fix Galaxy S21 Problems

If you run into a bug or performance issue on your Galaxy S21, Galaxy S21+, Galaxy S21 Ultra, or Galaxy S21 FE there’s a good chance you’ll be able to fix whatever is ailing your phone.

If you run into an issue, take a look at our list of fixes for common Galaxy problems. We’ve also released a guide that could help you fix battery life issues.

If you don’t find what you’re looking for in our guides, you should check out the XDA’s Galaxy S21 forums, carrier support forums (AT&T, T-Mobile, Verizon, for example), and the Galaxy S21 Reddit for potential fixes.

You can also get in touch with Samsung or your provider on social media sites like Twitter. Samsung’s also got a customer support line that could help.

What’s Next

Samsung continues to push monthly security patches to the Galaxy S21 series and these updates sometimes include bug fixes for lingering issues.

Software support for the Galaxy S21, Galaxy S21+, Galaxy S21 Ultra, and Galaxy S21 FE will last for years. Samsung currently provides four to five years of support to flagship devices like the Galaxy S21 series.

If your carrier offers an Android update schedule, keep an eye on it for details. Carriers like Rogers, Fido, and Telus in Canada and Vodafone in Australia keep their customers informed about upcoming Android software updates.

If your carrier has a similar schedule available, you might want to bookmark it and keep an eye out for details regarding incoming software updates for your Galaxy S21, Galaxy S21+, Galaxy S21 Ultra, or Galaxy S21 FE model.

Samsung’s launched its own Android 13/One UI 5 beta and it’s currently available for Galaxy S21, Galaxy S21+, and Galaxy S21 Ultra models in South Korea and the United Kingdom.

6 Reasons to Wait for the iPhone 14 & 6 Reasons Not To

Wait for a Hole-Punch Design

Wait for a Hole-Punch Design

If you hate Apple's notch, you might be in luck because it looks like the company is making significant changes to the iPhone's design.

Apple didn't eliminate the notch in 2021 but the iPhone 13 series has a smaller notch than the iPhone 12 series and previous iPhone models.

In 2022, Apple will reportedly ditch the notch in favor of a hole-punch display design. The rumor comes from respected analyst Ming-Chi Kuo. He's reiterated this in a newer note though he says the change may be limited to the iPhone 14 Pro models. 

A source speaking to MacRumors believes the iPhone 14 Pro's display cutouts might look like a single, long pill shape when the display is on. Bloomberg's Mark Gurman believes this information is accurate. 

Analyst Ross Young believes that while the iPhone 14 Pro models will be the only ones with this new design, the hole-punch design will likely come to all iPhone models in 2023. Young has reiterated this stance in two other reports

Korean publication The Elec backs up these rumors and claims Samsung Display will help with the manufacturing process. Like Kuo, the site says the new design will be limited to the Pro models. ETNews also says Samsung will supply OLED panels for the iPhone 14.

A newer report from The Elec states that the iPhone 14 Pro and iPhone 14 Pro Max will come with LTPO OLED displays with a hole-punch.

If true, it would put the iPhone more in line with Samsung's high-end Galaxy phones which also employ a hole-punch design.

The hole-punch isn't as invasive as the notch which should be music to the ears of those who don't like the notch.

Ice Universe and Duan Rui have both shared dummy images that show the devices new design in quite a bit of detail. 

Alleged CAD images of the iPhone 14 Pro Max hint at thinner display bezels. As for the lower-end iPhone 14 models, they're expected to keep the same thickness and bezel size as the iPhone 13 series. 

We've also seen renders of the alleged design Apple will deploy on the low-end iPhone 14 models. The renders, from MySmartPrice, hint at a design that's virtually unchanged from the iPhone 13's. 

The device in the images has a notch and it also has the same rear camera setup as the iPhone 13. 

We've also seen leaked iPhone 14, iPhone 14 Plus, iPhone 14 Pro, and iPhone 14 Pro Max display panels corroborate all of this information. 

Apple won a patent for under-display cameras for biometric authentication on the iPhone so it's pretty clear the company is working to get rid of the notch at some point. It's just a matter of when.

If you aren't thrilled with the look of the iPhone 12 or iPhone 13, think about waiting for the iPhone 14 Pro and iPhone 14 Pro Max.

    I have had issues with my S21 since I purchased. Samsung told me they are aware there are serious issues and the fix would not come before Aug/Sept. They recommended I send the phone to them, which I did and it came back with the same issues after being told my them that there is nothing wrong with it. My carrier, Xfinity has been NO help at all.
    My issue are: the phone does not receive calls about 50% of the time yet it does not show a missed call; many times it will not let me text; there are times it will not send my messages when I do text – the only correction for all this has been to restart the phone about 20 times a day. i have been a samsung owner for years and this is a terrible issue especially for safety!

    I have had a Samsung Galaxy S21Plus since March. My major issue is it randomly turns off and restarts and can do this several times in a row – off, on, off, on, off, on. I can be in the middle of writing an email or a phone call (it’s my business phone) and suddenly without any warning, turns off!!! It’s been happening pretty much since the beginning but has gotten worse in time. I have had enough so I took it to Samsung and they serviced it.

    I received it again and once again this fault continued. I took it back again and I got a call from them to say they couldn’t open it up to look as I haven’t sent it back 3 times yet! They want a video of it turning off and a verbal commentary of what happens. This customer service lady was very arrogant and didn’t listen or believe I was having massive problems with this DOA phone. It’s a dud and I won’t be buying another Samsung phone or product – not only because of the faulty products, but their customer service is nonexistent.

    Like the comment above, I have owned Samsung phones for around 20 years but that mean nothing to this arrogant company.

    I’ve tried to get help from Samsung, but get NOTHING. My phone does NOT RECEIVE CALLS AT ALL. I have spent HOURS with SAMSUNG TECH who have promised help and responses within 48 hours. NEVER HEARD ANYTHING; NO REPLIES WHATSOEVER after repeatedly discussing the problem. ATT says this is a daily and typical complaint because SAMSUNG CANNOT RESOLVE the software glitch causing this apparently PREVALENT and KNOWN PROBLEM. Phone newly purchased in July, 2021. I care more about making and receiving calls on my PHONE than I care about whether it has “super-duper cameras”. Why would I upgrade to another Samsung phone? Waiting one more week before instigating and filing class-action lawsuit.
