Its true that updates dont always bring good things.
Some updates have a tendency to mess things up rather than fixing what was wrong in the first place.
But, not all updates are something to fear.
Updates can also bring much-needed features and fixes.
If you have a Samsung equipment, you could try going to tweaks > Software Update.
If not, you could try going to controls > System > System Updates.
you’re free to also try checking in controls > Software updates.
Your gear will start looking for any pending updates automatically.
If you cant find the system update option, try going to About Phone.
Conclusion
Keeping your Android rig is always the best thing.
As you’re free to see, checking for software updates will only take you a few seconds.
