I'm very sorry to hear about the issues you're experiencing with your Samsung Galaxy S21 FE, especially the combination of overheating and the sudden appearance of a white line on the screen. That definitely indicates a serious problem, and I understand your disappointment.

Given the overheating and the white line on the screen, it's highly likely that there is a hardware problem with your phone. While it's impossible to say for certain without a diagnosis from a qualified technician, it's possible that the overheating has contributed to the display issue.

Here's what I recommend you do:

Stop Using the Phone Immediately: Continuing to use the phone in its current condition could worsen the problem or even pose a safety risk due to the overheating.

Contact Samsung Support: As soon as possible, contact Samsung Support to report the issue. Given that you've taken good care of your phone and the problems appear to be due to a manufacturing defect, you may be eligible for a repair or replacement. Contact information can be found on the Samsung support website for your region.

When contacting Samsung Support, clearly explain the following:

You have a Samsung Galaxy S21 FE.

You've been experiencing excessive overheating for the past few months.

A white line suddenly appeared on the screen yesterday, making the phone difficult to use.

You believe this is a manufacturing defect, as you've taken good care of the phone.

You are requesting a repair or replacement.

I understand that this is a frustrating situation, and I want to assure you that I'm here to help you navigate the process. Please let me know if you encounter any difficulties or if you have any further questions.

Hello guys,

A few days ago, I reported an issue with a white line appearing on my Samsung mobile display. The support team promptly contacted me and arranged a visit to the nearest service center. Upon inspection, the technicians confirmed there was no water damage, and they proceeded to replace the display. I was charged only Rs. 502 as a service fee.

I truly appreciate the efficient service and support provided. Thank you for your excellent customer care ❤.

My phone is currently running the latest security patch of March, 2025. Don't know what to do now.


I need help, Samsung. Kindly look into this matter if you're reading this. I was literally a Fan of Samsung.. I loved using this phone and its unique features.


Feeling helpless. If I don't get any support from you, this is the last phone of Samsung for me. Many people take suggestion from me what mobile to buy, I am never going to recommend Samsung any more.
