A Samsung Galaxy that gets hot is worth taking seriously — but it doesn't automatically mean there's a recall. Sometimes it's a software bug that a firmware update already fixed. Sometimes it's normal (fast charging and gaming push any phone hard). And sometimes it's a genuine safety issue. This guide walks you through how to tell the difference and what to do about each one.
Step 1: Check if your Galaxy model has an active recall
The most important Samsung Galaxy recall in history involved the Galaxy Note 7 in 2016. The Note 7 had a battery defect that caused units to catch fire — including during charging, in carry-on luggage, and while sitting idle. Samsung recalled the entire product line twice (first the original units, then the replacement units when those also caught fire). The Note 7 was completely discontinued.
If you somehow still have a Galaxy Note 7, stop using it immediately. The recall is technically closed, but the safety hazard is not. Contact Samsung at 1-844-365-6197 to confirm your options. Airlines will not let you board with one.
For all other Galaxy models: as of early 2026, there is no active CPSC safety recall for Galaxy S-series, A-series, Z Fold, or Z Flip overheating issues. Known overheating problems with Galaxy S23, S24, and similar models have been addressed via firmware updates, not recalls.

Known overheating issues by model (not recalls, but real problems)
Samsung has acknowledged overheating as a documented issue on several recent Galaxy generations. These are not safety recalls — the phones do not have battery defects — but Samsung has released firmware fixes and has in some cases replaced units under warranty.
Galaxy S23 series: Samsung released multiple One UI updates in 2023 addressing thermal management after widespread user complaints about the S23 Ultra and S23+ getting hot during photography, video recording, and gaming. If your S23 is still running an older One UI build, update it. Go to Settings > Software Update > Download and Install.
Galaxy S24 series: Similar pattern. The Exynos variant (sold in Europe and some Asian markets) ran hotter than the Snapdragon variant (US). Samsung tuned the thermal throttling via firmware updates in Q1 2024. If your S24 is heat-throttling during video or gaming, check for updates first.
Galaxy A-series budget phones: The A54, A34, and similar mid-range models use processors with less sophisticated thermal management than the flagships. Sustained loads — long gaming sessions, navigation with the screen on, continuous video recording — will get these phones warm. That's expected behavior, not a defect.
Galaxy Z Fold / Z Flip: Foldable phones pack a lot into a small thermal envelope. The hinge area tends to concentrate heat. This is a design tradeoff, not a defect. If your Z Fold or Z Flip is getting uncomfortably hot during normal use (not heavy gaming or video), run a software update first.
Normal heat vs. abnormal heat: how to tell the difference
Not all warmth is bad. Here's how to read what your Galaxy is telling you.
Normal: Phone feels warm during fast charging (especially if you're using a 45W or 65W charger). Phone gets warm after 30+ minutes of gaming or streaming. Phone is warm in a hot car or direct sunlight. These are expected behaviors.
Abnormal — investigate further: Phone gets hot during a phone call or with the screen off. Phone gets hot with no apps running. Battery drains very fast alongside the overheating. Phone shuts itself off due to heat even in a normal room. These patterns suggest either a software problem (runaway background process) or a hardware issue.
Signs of a battery problem specifically — these warrant immediate action: Phone has swollen and the back is bowing outward or the screen is lifting. Any burning or chemical smell, especially during charging. Charging cable or the charging port area gets hot (not just warm). If you see any of these, power off the phone, unplug it, and don't use it until you've had the battery checked.
What to do if your Galaxy is overheating
Start here before contacting Samsung.
Update your software: This fixes more Galaxy overheating problems than anything else. Settings > Software Update > Download and Install. Also update your apps — a rogue app running in the background can pin the CPU at 100% indefinitely. Go to Settings > Battery and Device Care > Battery > Background Usage Limits and check which apps are consuming power while idle.
Reboot in Safe Mode: Press and hold the power button, then press and hold Power Off until you see the Safe Mode prompt. Safe Mode disables all third-party apps. If your phone stops overheating in Safe Mode, a third-party app is the culprit. Restart normally, then uninstall recently installed apps one at a time until the problem stops.
Check for a runaway process: Settings > Device Care > Battery shows you exactly which apps used the most battery in the last 24 hours. Anything consuming over 20% of battery when you're not actively using it is suspicious. Clear cache for that app, or uninstall it if you don't need it.
Avoid charging overnight with a case on: Charging generates heat. Cases trap heat. Together, especially overnight on a bed or couch, they can push temperatures higher than they need to go. Charge on a hard, flat surface without the case for better airflow.
Factory reset (last resort): If a software update, Safe Mode test, and app audit don't fix it, a factory reset will eliminate any corrupted software. Back up your data to Samsung Cloud or Google first. Settings > General Management > Reset > Factory Data Reset.
If none of this works: Your hardware may need service. Samsung covers manufacturing defects under warranty (1 year in the US, 2 years in the EU). Contact Samsung Support at samsung.com/us/support or visit a Samsung Experience Store or authorized service center.
When to escalate to Samsung or a repair shop
You should contact Samsung directly — not just do DIY fixes — if any of these apply.
You've tried software updates, Safe Mode, and a factory reset and the overheating continues. Your phone is less than 2 years old and getting hot during basic tasks like browsing or phone calls. Your battery is draining significantly faster than it did 6 months ago (a sudden drop of 30%+ suggests battery degradation). The back of the phone feels hot, not just warm, while charging.
Samsung's warranty covers manufacturing defects but not physical damage (cracked screen, water damage). If your phone is out of warranty, authorized third-party repair shops can replace the battery for $50-$100 in most markets, which is often the right call for a 2-3 year old phone that's started running hot.
Do not use third-party replacement batteries from unknown brands. Counterfeit and non-OEM lithium-ion batteries are a documented fire hazard. Use OEM Samsung batteries or batteries from authorized repair centers.
