Why Redmi 4X screen breaks more often than others and when repairs are imminent
Smartphone Xiaomi Redmi 4X (The codename santoni is still one of the most popular budget devices in the aftermarket, despite its release in 2017. IPS-A thin-glass screen that cracks even from a small impact, according to service centers, more than 60 percent of Redmi breakdowns. 4X associated with damage to the display is 2 times more often than the flagship models Xiaomi.
The reasons for the failure of the screen are divided into two categories: mechanical (falls, pressure, fluid intake) and technical (fragmentation of the plume, burnout of the backlight, factory defect). If after a fall on the display appeared "spiders", black stripes or the sensor stopped responding to touch - repair is inevitable. It is not necessary to postpone it: glass fragments can damage the internal components, and the entry of dust under the panel will accelerate the corrosion of contacts.
Redmi 4X owners often face another problem: unoriginal parts. The market is full of cheap Chinese copies of screens that after 2-3 months start to turn yellow, lose sensitivity or completely stop working. So before repairing it, it is important to understand how much a quality replacement costs - and where to make it, so as not to overpay for a second visit to the service.
Official service vs. informal workshops: where cheaper and more reliable

- 🔧 Authorized partner workshops – prices are lower than in official centers, but the quality of spare parts is controlled by Xiaomi.
- 🛠️ Unofficial services are the most budgetary option, but the risk of running into fake or poor-quality repairs is rare, and if they are given, then for 1-3 months.
- 👨🔧 Self-replacement is the cheapest, but requires skills and tools, and is only suitable for confident users.
Important: in official centers Xiaomi can refuse repair if the smartphone was unlocked (removed Mi Account) or stitched custom firmware. Before visiting, check the lock status in the Settings menu → About phone → Mi Account status.
