My Galaxy S4 went and downloaded the Android 4.3 upgrade. I have NOT installed it. An icon stays at the top of the phone to remind me to install it, and a system window appears every now and then during the day to have me install it or postpone it to later (all I can do is choose a reminder interval of 30 minutes, 1 hour or 2 hours - there's no option to just have it go away). I do NOT want to install this upgrade since I just got my phone a couple of weeks ago, it works fine, and I don't want to take the risk of "fixin' something that ain't broke" and have it all go wrong (as per some of the issues I've seen people raise in forums out there). I am running 4.2.2. on model number GT-I9506 (in France), and my firmware is: AP: I9506XXUAMJ2 CP: I9506XXUAMI1 CSC: I95606FTMAMI2 Can I go somewhere on the phone to remove this downloaded file? Is there a way for me to have the phone stop harrassing me with reminders to install the upgrade? Also, I did a backup with MyBackupPro (anticipating that I might need to do a factory reset and be able to restore my info/apps/settings quickly with this 4.3 upgrade nonsense if I had to accept), but it's not a full backup like I used to be able to do when I used to have a Windows phone several years ago. I paid for Titanium BackUp Pro since I read that it could do an exact copy of your current system and be able to restore that image if needed, but it's saying that my phone is not rooted. I've read about rooting, and I am not at all technically inclined, so I am not comfortable doing this. Does this mean that there is no way for me to get a full system restore the way I used to be able to on my Windows Phone several years ago unless I embark upon the process of trying to root my phone?
