To do factory reset or not?

[Anonymous]

Have Xperia Z1 Contact.  No complaints at all.

Currently waiting to decide whether I will bother to update to Kitkat after o2 release the .757 fix (been reading Sony Xperia Contact forums and am reluctant). I would love to know how many users do such updates without doing a factory reset as have heard various opinions.  Some say do factory reset before and after the upgrade, some say only after, yet with my Galaxy s2 I never did factory reset and all was well.  Am trying to avoid having to reset everything!

If anyone on here can share their preferred way of doing this I would be pleased to hear what is recommended.

A factory reset is indeed a last resort.

Some don't have issues after updating but some do so the generic solution is to try a hard reset.

It's the owners choice.

If no joy then sometimes contacting the manufacturer support is another resolution.

1st line support will always tell you to do a reset first.

It's standard practice for any troubleshooting.

Thank you but can anyone explain what the thinking is for for doing a reset first?  I could understand it if doing so actually uninstalled Jelly Bean prior to updating to KK but I get the feeling that is not the case. I am just curious as cannot think many users routinely do a factory reset whenever they upgrade as very few people ever mention it.

Lots of users do do a factory reset the ones who don't tend to put up with little things that don't sit right after an upgrade

Hi

The process is understood to remove any possible conflicts from the old firmware / settings with the newly downloaded firmware.

Think of it as spring cleaning and decluttering. All the old files will be deleted and it ensures there is no conflicts with replaced files of same name etc.
Above all else it's good practice and common in the Android world.
