I would like to find out how to raise a formal complaint regarding my ongoing experience with the Samsung Flip4 256GB. After initially receiving a replacement for my first device, which had issues with the microphone, screen, and other malfunctions, I am now facing significant problems with the replacement unit as well.

The current issues include:

• The phone randomly turns off, even when fully charged, particularly when folded.
• Dark mode toggles itself on and off without any input.
• The device frequently overheats, even when idle, leading to severe lag and further battery drain.
• The phone loses about 10% charge per hour.
• The cover screen intermittently stops working.
• The phone is generally laggy and slow

These problems make the phone nearly unusable. It's clear from the numerous forum posts and online discussions that I’m not alone—many users are experiencing similar issues. Every update Samsung releases seems to exacerbate these problems rather than fix them.

This phone cost over £1,000, and the quality of both the hardware and software is appalling. The ongoing issues are directly impacting my work and daily life. I rely on this phone for essential tasks like commuting (tickets), payments, and communication. When the phone dies due to battery issues, I am left stranded and forced to pay out of pocket for services that the phone should be providing.

It's disappointing that Samsung hasn't issued a recall for these faulty devices and instead expects users to pay around £400 for repairs, when the trade-in value of the phone has plummeted to only £150. To make matters worse, despite my device being 256GB, many trade-in companies fail to recognize the IMEI number or incorrectly identify the phone as a 125GB model, further devaluing it.

I am seeking guidance on how to formally raise a complaint and pursue a refund or compensation. If Samsung is unwilling to address these issues, I would like to know how to escalate this matter with the creditor used for financing in the UK. Alternatively I will seek help from a ombudsman.

This situation is unacceptable, and I believe there must be a remedy. Samsung should take responsibility for the persistent issues plaguing these phones and offer compensation to affected customers.
