The issue persists even after a full charge and factory reset as per the user manual. Legal basis: Pursuant to the EU Consumer Rights Directive (2011/83/EU), the seller is obliged to deliver goods in conformity with the contract. I am entitled to a remedy for any lack of conformity within a reasonable timeframe. Desired resolution: I request a replacement with a new, defect-free product. Should this complaint not be resolved within 30 days, I reserve the right to withdraw from the contract and escalate the matter to the relevant consumer protection authority. Yours sincerely, John Smith
