Today I purchased a used Nexus 4 8gb. Now by checking the phone deeply I came to know that it is rooted on vesion 4.4.2 . It is also showing two system updates ( 4.4.3 and 4.4.4 ) to be downloaded. As I am not fond of rooting or even don't know what's the use of rooted phone . Should I continue with it or can I update to latest version by downloading and installing the to be downloaded updates ? Is it safe to download and install OTA update on rooted phone ? Thanks in advance.
