Understand the fault, choose the right repair. Phone repair, care and how-to guides from the Cep Market repair team.
If your phone rings or vibrates but the screen is black, the phone is on; the problem is the screen or its connection. Force restart and charge it first. Shine a torch close to the screen in the dark: a faint picture means a backlight fault. If it started after a drop or liquid, the screen is usually replaced.
Vertical, horizontal or coloured lines on the screen usually mean the display panel or its connection is damaged. A quick screenshot test tells you in seconds whether the problem is software or the panel.
Not every Xiaomi, Redmi or POCO phone has a screen that shows battery health. With a service code typed in the dialler you can see the battery’s current and original capacity and work out its health yourself.
