1st galaxy note 3 was disaster after kitkat update. It basically disabled my sd card. I was mad!!!. It wouldn't let me revert back to jellybean 4.3. I imediately swapped note 3 for another before my 14th day. Tried everything on forums to stop download of kitkat system notification, but to no avail. Then got wind that after 2 wks the kitkat would download automatically w/out my permission! I went into a panic to figure this out before it was to install kitkst on my 2nd unreturnable phone & destroy it too. So far so good. I originally had disabled "Google framework services".in apps manager, like the post said to do, but it didn't work either. This is a no-root solution that worked for me. I take no responsibility to damage to your phone for this. As its just what.has worked so far for me. It's not a perfect solution, but it seems to have worked & the kitkat downloaded notification has stopped pinging me to upgrade to kitkat!
If you already have upgraded to kitkat, this might not work for you. Here's what I did. WARNING: Before going forward with this, back up all your data. Send pics.videos to sd card or store in cloud.Unmount your sd card. Power down phone & remove sd card. Power phone back up.
1)Go to setting, click on general settings,
Click on "Back up & restore" , then click on "FACTORY DATA RESET"...When you do phone will reset to like it was new out of box. Everything you put on or changed will be erased, but the kitkat notification will be removed also! Not sure if it will work if kitkat is already installed before factory data reset. You can try & see. When phone reboots, it will at some point ask you to keep on the "Sprint wifi optimizer to save battery power. IGNORE THAT REQUEST & make sure it is off or otherwise "unchecked" so it won't search out & lock on wifi signals when it finds them. -DONT SKIP THIS STEP-
2) Click on settings, click on "general",
Click on "system update".
3) Un-check "Auto-update" if it is checked.
4)Do check "Downloadable on.wi-fi only"
5) If it is checked, uncheck"Download update on wireless network" (very important).
6)Back out to general setting again.
7) Scroll down & click on "Security" Note: if you're using you phone your for banking, you might reconsider this step. As I do all my internet purchases with a prepaid card for safety.anyway.
8)Scroll down to "Security update services".
9) Uncheck "security policy updates". This prevents it from automatically checking for & downloading any updates to security such as is noted in the kitkat
update which is why they basically disabled the sd card on the.phone.
10)Look at "VIA WIFI ONLY" right under this section and make.sure to uncheck it if it is checked. It says it will only update security policy when connected to wifi.
So far I haven't seen the kitkat system update download to the notification bar since I done these changes. Its been 4 dsys so far. If you use WI-FI again though, it will immediately start the kitkat download again to notification bar. I tried it momentarily. It started kitkat download, I shut off wifi real quick to make it fail . Thank goodness it worked so I would have to do another factory data reset to reset the kitkat 13 day automatic download clock again. It appears that.in.a hurry, you can do a factory data reset to start the clock over if you don't have time to do the above steps right now. That's what I did. Its was better to me to reset than to loose my operational sd card forever. Can't return this phone again. I've got 3g at home & 4g most.of the time. So the 4g.is fast enough for me to live with without having to depending on a.wifi connection.
I also have an un-limited data plan thru sprint. I can live with it. Depending.on.your data plan this might not wk for you on verizon or At&t. But it was the only way I could keep my sd card operational, which is why I bought this phone. If you discover easer option to stop the kitkat update, pls reply. If this wks for you too. Pls let me know in the reply section. Hope this helps.
