12–24 Month Warranty & 24/7 RMA Support

At JH Screen (Shenzhen Hongshengtong Photoelectric Co., Ltd.), shipment delivery marks the beginning of a long-term strategic supply partnership rather than the end of a transaction. Every iPhone replacement screen assembly we manufacture is backed by a comprehensive 12 to 24-month factory warranty directly traceable via the unique laser batch code engraved on the stainless steel backplate during Step 49 of production. Our dedicated international after-sales engineering team operates 24/7 with an average response time of 3 hours or less, providing immediate technical support on iOS firmware updates, True Tone programmer compatibility, original touch IC grinding and soldering transfer parameters, and repair shop installation best practices. In the rare event that a screen exhibits a manufacturing or functional defect—with our 51-step Class 1K/10K cleanroom QC and 72-hour aging test keeping RMA rates well below industry averages—our streamlined warranty protocol protects both your cash flow and your local brand reputation. You can simply log defective units by laser batch code along with brief video or photo verification with your account manager to receive direct 1:1 brand-new replacements or credit deductions on your very next restock order, eliminating expensive single-unit international return shipping delays. Any returned batches are thoroughly examined in our Shenzhen R&D failure-analysis laboratory using AOI microscopes and thermal chambers to issue formal 8D root-cause corrective reports. Furthermore, as a long-term wholesale partner, you receive priority production allocation, locked-in quarterly volume rebates, and early-bird sample access to the 27+ new display models our 20 R&D engineers launch each year.
