plan to buy to apply for the back glasses of note 7. even with cases, still prone to get scratch, so before put in casing, apply the liquid armor haha..

Bro what do you mean by the need to trim the corners? Did they do it for you? Before or after installation?

Here you go :

XDA S7 Edge Batman Theme

Due to it require to purchase Pakage Disabler, so I can't really try to apply the theme. 

I think you can't just install and apply normally, you have to use Package Disabler Pro to do some tweaking, below will be the full tutorial :

Wah, you bought Package Disabler ?   

is it? For me the whole process only took 1 min. The only difficult part in here is that some people may feel reluctant to buy PDP, which I think it's quite irony, You could spend 3K to buy a phone but you can't pay a few ringgit to buy a good app?

hahah u remember my cheapskate attitude huh 

No matter what, i will still have to call and inquire them regarding this.

i hope if we wait few weeks then exchange still OK cos i dont want to go without a phone even though i have extra phone at home but dont have any that support nanosim

Yes. They just modified their post to 1 to 1 exchange. [attachmentid=7447143]

Done calling samsung CS, same thing as bro jerryhean said, they will follow up with a call from the marketing team to advice what's the next step to do... luckily this is not my main phone.. at least can chillax sit tight and enjoy a cuppa...

Send he phone in and need wait 2 to 3 weeks? Or 2 to 3 weeks from now?

replace je bro, not worth the risk
