Galaxy S24 overheating on video calls, thermal warning messages, hot phone during Zoom or Teams — safe temperature checks (brightness, apps, ventilation, cache) before you reset

Technician avatar Technician
I hear you — when your Samsung Galaxy S24 gets hot during video calls, it feels like something is seriously wrong. The good news is that most thermal issues are reversible with safe, simple checks.

Trust moment: we’re not going to reset your phone or change advanced settings without understanding what’s happening first. Let’s start with the basics.

Quick question: does the phone feel hot to the back (near the camera), the sides, or all over? And does it happen on every video call, or mainly on longer ones?
Customer
It’s the back, mostly. Happens after about 10 or 15 minutes into a Zoom call. It gets really warm, and sometimes I see a message saying “Device is getting hot.”
Technician avatar Technician
That’s a clear pattern — the back of the phone is where the processor and camera hardware live, so that makes sense. The “Device is getting hot” message is Samsung’s thermal throttling warning, which means the phone is trying to protect itself by slowing down.

During a video call, your S24 is doing a lot at once: camera streaming, microphone, display at full brightness, Wi-Fi or mobile data, and sometimes background apps. That’s a heavy load. Before we assume something is broken, let’s check three things: display brightness, background apps, and ventilation. Are you using the phone on a table, in your hand, or propped against something?
Customer
I usually hold it in my hand during the call. The screen is pretty bright — I think it’s set to automatic brightness.
Technician avatar Technician
That’s helpful. Your hand is blocking the back of the phone, which traps heat. Automatic brightness can also run the display at higher levels than you need during a call, and that drains the processor more. Let me ask one more thing: are you using the Zoom app, the web version through a browser, or something else?
Customer
The Zoom app. And now that you mention it, I have a lot of other apps open — email, messages, some news apps I think are running in the background.
Technician avatar Technician
There’s your recipe for heat: the Zoom app is demanding, your hand is blocking airflow, the display is on automatic (possibly brighter than needed), and background apps are competing for processor time. Together, they push the S24’s processor into heavy load, and the heat builds up.

Trust moment: I don’t want you uninstalling apps or changing settings you’re not sure about. Let’s start with three safe, reversible checks that often cool things down dramatically. Sound okay?
Customer
Yes, that sounds good. What do I need to do?
Technician avatar Technician
Perfect. Here are the three safest steps:

1) Reduce display brightness during the call. Swipe down from the top of the screen twice to open Quick Settings, and look for “Brightness.” Lower it to around 40–50% during calls. You can always raise it back after.

2) Use a phone stand or prop the phone up so your hand isn’t covering the back. Even a cup or a small book works. This lets heat escape.

3) Close background apps before you start the call. Swipe up from the bottom (or use the back button) to see recent apps, and swipe up on apps like email or news to close them. Leave only Zoom open if possible.

Try those three on your next call and see if the phone stays cooler. Does that feel doable?
Customer
Yes, I can do that. But what if it’s still hot even after I try those things?
Technician avatar Technician
Good question. If it’s still hot after those three changes, we have a few more safe checks before considering anything deeper.

Check the Zoom app settings: Open Zoom, go to Settings (usually a gear icon), and look for video or camera settings. Sometimes turning off “HD video” or “mirror my video” can reduce the processor load.

Check for app updates: Open the Google Play Store, go to “My apps & games,” and see if Zoom or your system has pending updates. Older versions can be less efficient.

Restart the phone: Power it off, wait 30 seconds, and turn it back on. This clears temporary memory and can help the system run more smoothly.

If it’s still warm after all that, it might be worth checking if the phone’s thermal sensors are working correctly or if there’s a background process we haven’t identified. But let’s start with those checks first.
Customer
Okay, I’ll try the brightness, stand, and closing apps first. Then I’ll check the Zoom settings if needed. What about clearing the cache or something like that?
Technician avatar Technician
Cache clearing can help, but it’s usually a later step. Here’s why: cache doesn’t usually cause heat during a live call — it’s more about performance over time. If brightness, ventilation, and closing apps don’t help, then clearing cache might be worth trying. But let’s not do that yet, because it’s one more thing to change and we want to know which fix actually works.

One last thing to mention: if the phone ever shows the “Device is getting hot” message and suggests you close apps or lower brightness, that’s Samsung’s built-in thermal management telling you the same thing we’re doing now. So you’re not breaking anything by following those prompts.
Customer
That makes sense. I’ll try those steps and see what happens. Thank you — this is much less scary than I thought it would be.
Technician avatar Technician
I’m glad. Most of the time, overheating during video calls is about load management, not a hardware failure. Your S24 is a powerful phone — it just needs a little breathing room and some brightness adjustment when you’re pushing it hard with video streaming. Let me know how it goes, and if the warmth comes back even after those changes, we can dig deeper into app-specific settings or battery health.

Quick answer: the accepted fix

Accepted first fix for Samsung Galaxy S24 overheating during video calls (safe approach): 1) lower display brightness to 40–50% during calls (swipe down twice for Quick Settings), 2) use a phone stand or prop so your hand doesn’t block the back (heat needs to escape), 3) close background apps before starting the call (swipe up on recent apps to close them), and 4) check Zoom settings for video quality or mirror options that can reduce processor load. If overheating persists, restart the phone, update the Zoom app, and monitor whether the “Device is getting hot” warning appears less often. Thermal throttling is a safety feature, not a sign of permanent damage — but sustained heat during routine calls suggests the phone is working too hard.


Why the Galaxy S24 overheats during video calls (and why it starts on newer phones)

Video calling is one of the most demanding tasks a smartphone performs. The Samsung Galaxy S24 has a powerful processor and a bright AMOLED display, both of which generate heat when running at full capacity. During a video call, the phone is simultaneously streaming video from the camera, processing audio, keeping the display on at high brightness, and managing Wi-Fi or mobile data. If the phone is held in your hand, the back (where the processor and camera hardware sit) gets blocked, trapping heat. Add background apps running in the memory, and the processor works even harder to juggle everything. The phone’s thermal management system then kicks in with throttling (slowing the processor) or warning messages to protect the device. This is normal behavior — the phone is protecting itself — but it means the current load is too heavy for the current cooling conditions.

What to check first (safe checks before changing anything advanced)

Start with the simplest and safest step: lower the display brightness during the call to around 40–50%. Display brightness is one of the biggest power consumers on modern phones. Next, ensure the back of the phone is not covered — use a stand, prop it against something, or hold it by the sides instead of the back. Third, close any background apps before you start the video call; swipe up on recent apps to close them completely. If the phone still feels warm after these three changes, check the Zoom app’s video settings (HD video or mirror options can be turned off), update the app if there’s a pending update, and restart the phone.

Galaxy S24 thermal management explained — calm, senior-friendly guidance

Heat during video calls is usually a load and cooling issue, not a hardware defect.

If your Samsung Galaxy S24 keeps overheating during video calls, don’t panic. The phone is designed to warn you when it’s getting too warm, and it will slow itself down to cool off. This is a safety feature. The most common causes are display brightness set too high, the phone being held in your hand (blocking airflow), too many background apps, and video streaming at high quality. All of these are reversible. Lower the brightness, give the phone room to breathe, close unused apps, and try the call again. If the warmth persists even after these adjustments, the next step is checking the app settings (like Zoom) to see if you can reduce video quality, or restarting the phone to clear temporary memory. Rarely, a background process or battery issue might be causing extra heat, but that’s something we can investigate safely without resetting your phone.

Disclaimer: This information is AI-generated and intended for general guidance only. Avoid forcing the phone to run hot apps continuously or blocking ventilation intentionally. If the phone shows persistent thermal warnings even at rest, or if the battery is swollen or leaking, stop use and contact Samsung support or a certified technician.

If the issue continues


Getting Started Is Easy

Ask for help, 24/7

If your Galaxy S24 feels hot during video calls, start with the safest checks: lower brightness, use a stand for ventilation, and close background apps. These changes usually make a big difference within one or two calls.

Expert will respond in minutes

Most Galaxy S24 overheating during video calls comes down to display brightness, processor load from background apps, or lack of ventilation. These are all reversible without resetting the phone.

Stop thermal throttling warnings

Once you reduce the processor load and improve heat dissipation, the “Device is getting hot” warnings should disappear, and your video calls will feel smoother and more stable.

FAQ

Is it safe to use my Galaxy S24 when it’s hot, or should I stop immediately?

It’s safe to use the phone even when it’s warm, but the “Device is getting hot” message is Samsung’s way of saying the processor is being pushed hard. If you see that warning, lower the brightness, close apps, and give the phone a break if possible. The phone will slow itself down (thermal throttling) to cool off, which might make video calls less smooth temporarily. Stopping the call and letting the phone cool for a few minutes is fine, but you don’t need to panic or force a restart.

Does overheating during video calls mean the battery is failing?

Not necessarily. Heat during demanding tasks like video calling is normal. However, if the phone is hot even when you’re not using it, or if it drains battery very quickly, then there might be a battery or background process issue. Start by checking if any apps are running in the background (Settings > Battery > Battery usage) and closing unused ones. If the phone stays cool after reducing brightness and closing apps, the battery is probably fine.

Can I use a phone case or cooling fan to prevent overheating during calls?

A thick phone case can actually trap heat, so removing it during video calls might help. A cooling fan or cooling pad is not necessary for normal use. The best approach is to improve ventilation naturally: use a stand, prop the phone up, and keep the back uncovered. If you’re concerned about heat, a thin case (or no case) is better than a thick one during demanding tasks.

Should I clear the cache or reset the phone if it keeps overheating?

Not immediately. Clearing cache is a safe step that can help with performance over time, but it’s unlikely to solve overheating during video calls. The issue is almost always about current load (brightness, apps, video streaming), not cached data. Try lowering brightness, closing apps, and checking Zoom settings first. If the phone is still hot after those changes, clearing cache (Settings > Apps > [App name] > Storage > Clear cache) is a reasonable next step. A full reset should be a last resort, not an early fix.
