No. OTA only possible on stock rom n stock kernel
Root is still OK

Contact bank n request activation of your card for online purchases. Activation is immediate

I noted you are dead serious n concerned about such stuffs having installed already several such related apps in your phone
You must be a VIP so concerned about your phone security
For me all these are superfluous stuffs. If I lose my phone or even hacked no worries as I has zero confidential stuffs inside except contact address n tel nos

Simply put anything you transact through internet is never safe. That is why I never do bank transactions on my phone
No matter how much security controls you put in it can be hack sooner or later
I don't even bother to use all those security password apps to protect one data. Don't put such stuffs in phone than no worry about it getting hacked
You can be preventive but there is never a guaranteed you will be 100% safe
The phone is the worst tool to put such stuffs as it is easily lost or stolen
If you need decode the description so that only you know what it means eg in my previous old Nokia I will put a contact name and tel no as my bank account number n if number too long I split it into 2 as a postcode. Only I know which contact name is my bank. I am amazed so many users just happily key in directly their bank name n account Nos in phone n protect it with those password apps thinking is safe

Through my Mac at market.android.com
And I pay for every single paid app n NEVER use a single pirate crack app. So I don't believe in even using those security apps which I think maybe necessary for those who download such

Sorry long time never touch windows mobile. Last was HTC hd2

Unfortunately true that LTE update slower
Since he work in spore more sense to get in spore
If LTE look for coverage of 4g as different telcos different n limited coverage

Of course you can edit it

Careful Korean phones uses different type of GSM/LTE from most Asian countries
Check n reconfirm before update

That shows you do not have full root , only partial rooted
Re root your phone and reflash your rom

Yes

Go to settings/apps look for playstore n Google services framework select clear data n restart phone
If still have similar error last resort remove your Google account n key in again

If you do factory reset the very first time it will wipe your internal sd clean. Subsequent will not
Advisable to setyour titanium backup to external sdcard as default is at internal sd. Do this at menu/preference/backup folder n search device
Before that create folder titaniumbackup at external sdcard first

E Warranty is just an additional service
As long as you have register your phone and even did not , but have the official receipt , your warranty is still honored
The advantage of registering is you need not show proof of purchase during any warranty claims

In my opinion that is a piece of dumb ad by Samsung
It will only appeal to non tech or non knowleageable users
You don't openly compare software with opponent hardware features -really dumb
