Recently, Google release Android 4.3 updates but when I check system update on my nexus4, it’s shows no updates available and it’s still stuck to 4.2. But one of my friend have got update on his nexus4.
Then I found some tricky solution of this. Please follow below steps:
If you haven’t received the update yet, go to Settings and select Apps. There select “All” and scroll till you find Google Services Framework. Select that and click on “Clear Data”, which would give you a warning. Disregard the warning and go ahead with it. Once done, go back to Settings, scroll till the end and select “About phone”. From there select “System updates”. It would show last checked for update sometime in 1970, which is alright. Now check for update again. It takes a few attempts and if you don’t get the update, repeat all the steps again.
Also, I have repeat this steps 2-3 times and then I got the update :). Hope this works for you guys.
