The Google Nexus 4 has gained positive reviews overall with the advantages of impressive features and affordable price. However, the shortcoming is that the front and back glass tend to break easily. Many users complained they cracked the back glass on their N4. However, the damage caused by personal factor is out of warranty. LG won’t replace it for free. Besides, it’s difficult to replace the Nexus 4 back cover glass lens alone. Fortunately, you can replace the whole Nexus 4 back cover easily yourself according to our step-by-step tutorials.
