Can Samsung be honest about device overheating issues. Is it a hardware problem. With a flagship like the S24 Ultra, the device overheating happening several times a day is not acceptable. If I could I would sell and try iPhones for the first time. I don't feel confident selling to someone a phone with such issues. Yes I have tried restarting, wiping cache, I have even flashed and downgraded the software, I have shut all background processes, I have done it all. But the problem still persists
Hi I hear you. With a flagship like the Samsung Galaxy S24 Ultra, frequent overheating is definitely not normal—these devices are designed to handle heavy workloads without becoming uncomfortably hot several times a day. Based on what you’ve done—restarting, wiping cache, flashing and even downgrading software—it seems like this isn’t a simple software glitch. That points strongly toward a hardware issue, most likely:
Thermal paste or heat dissipation problem in the chipset.
Faulty battery or internal component generating excessive heat.
Design or batch defect (even premium devices can sometimes have a manufacturing defect).
Samsung is generally cautious in admitting hardware defects openly; their official stance tends to focus on software fixes first. But in reality, frequent overheating despite all troubleshooting steps is hardware-related, not software.
From a practical standpoint:
1. If it’s still under warranty, insist on a full diagnostic or device replacement. Flagship devices like the S24 Ultra shouldn’t have recurring overheating.
2. Selling a phone with persistent overheating is risky—buyers can notice, and it can be unsafe. You’re right to feel hesitant.
3. If Samsung refuses to acknowledge a hardware problem, you might be better off requesting an official replacement or refund, rather than trying to sell it.
The device itself won't actually be overheating, the message comes and it will even switch off at times. There is a time I switched off the phone for 48hrs, as soon as I switched on the message came and it switched itself off.
Ah, that detail actually makes the situation much more serious, If your S24 Ultra shows an overheating warning immediately on startup, even after being powered off for 48 hours, and then shuts itself down, that strongly points to a hardware-level fault, not software. The device itself likely thinks the CPU or battery is overheating, even if it isn’t physically hot. This is usually caused by:
1. Faulty temperature sensor – the chip that monitors device heat could be malfunctioning.
2. Battery issue – a defect in the battery circuitry can falsely trigger overheat warnings.
3. Motherboard or chipset defect – sometimes a component on the board itself can short or misreport temperatures.
At this stage:
No software fix (cache wipe, firmware flash, downgrade) will permanently solve this.
It’s unsafe to use, because sudden shutdowns can risk data corruption or worse.
Samsung must treat this as a hardware failure under warranty—this is not typical behavior for a flagship phone.
Your best move now:
1. Do not continue using the phone for regular tasks; even charging can be risky.
2. Take it to an official Samsung service center immediately. Explain exactly what you described: “overheating warning on startup, shuts down immediately, persists after full power off for 48 hours, all troubleshooting done.”
3. Ask for a replacement unit under warranty. For a brand-new S24 Ultra, they shouldn’t hesitate if the hardware is defective.
