Xteink warranty covers defects, not a cracked screen.

# The 30-day return and the 1-year warranty

The X3 and X4 have two coverage clocks, both starting on the delivery date. Check the 30-day return first. A return or exchange is a stronger remedy than a warranty claim.

Both clocks exclude physical damage. A drop, crack, or scratch closes each door. The matrix below maps eight real scenarios onto the policy.

# What is and isn't covered

Eight real scenarios and where each one lands. CrossPoint is community-built alternative firmware for the X3 and X4.

A crack from a drop, a clip, or a cheap protector is user damage. See the clip-on light break (Jun 2026, 143 points, 51 comments) and the glass-protector PSA (May 2026, 154 points, 38 comments), then skip to your DIY options. The full story of both breaks is on the prevention guide. White X4 fading in sunlight is a firmware fix, not a repair. See the sunlight-fade fix.

# How to claim, then when DIY is smarter

Work these in order. It keeps the free options open.

1. 1
   Check the purchase date

   If it's within 30 days and the damage is not physical, attempt a return or exchange through the official channel first.

2. 2
   Email support with photos

   Write to support@xteink.com and describe the damage. Even out of warranty, some owners report Xteink offering paid replacement guidance. Include the model, purchase date, and the nature of the damage.

3. 3
   Check whether a warranty claim applies

   If the screen failed without physical impact, it may qualify under the 1-year manufacturing-defect clause. That includes dead zones and a total blackout.

4. 4
   Weigh repair against replacement

   A new X4 runs about $69 and an X3 about $79, so a DIY panel-and-tools swap can cost nearly as much with an uncertain outcome. The full repair-vs-replace math is on the cracked-screen guide.

5. 5
   Only then, go DIY

   Attempt a DIY repair only after the options above are exhausted. See your DIY repair options.

# Custom firmware & your warranty

Xteink's policy is hedged, not a flat refusal. The exchange/return page says "unauthorized hardware disassembly or firmware modifications may compromise device integrity" and that such modifications "may limit the effectiveness of standard repair protocols." Coverage is reduced for modified devices, not automatically zero.

Liliputing reported in 2026 that Xteink applied firmware restrictions to X3 and X4 units bought through Chinese domestic retailers like Taobao, not to any particular model. Units bought from the official Xteink store or Amazon were later confirmed to not restrict the use of third-party firmware. In practice, custom-firmware devices are excluded from repair assistance, so contact support directly before assuming that's final.

Reflash to stock firmware before you write to Xteink.

# Official support contact

Attach clear photos of the damage, and say honestly whether the unit is on stock or custom firmware.
