There are few options to fix a damaged screen on an iPhone XR. One is by getting it to service at your local Apple Service Center; the second method is by changing the LCD by yourself. However, if you do not want to risk damaging the phone accidentally or losing all your precious photos and documents due to the privacy restriction, then the best option is to get it to fix by a trustworthy repair shop in Singapore.
Take note that the flex cables attached to it is very easy to tear, especially the face id camera connector. Once it is damaged, the Face ID would be permanently damaged as the sensor is embedded to its own motherboard and cannot be replaced.
If you are too busy or inconvenient to visit our shop, you can even select home delivery service whereby our driver will pick up your faulty phone. Once phone are fixed, we will then deliver to your place within the same day.
An iPhone XR screen replacement should set you back for $130 at a decent repair shop such as Hitec Mobile. Just make sure you don`t get hoodwinked by an unreliable repair shop that promise you 100% original LCD and end up paying higher price for a refurbish one. If anything, there is no such thing as original parts from Apple unless it is taken from another iPhone.
