not necessary..
old days battery yes..

nowadays the battery are not like last time already.

but i still advise senior citizens to charge 8 hours. lol
you know their mentality. cannot accept new stuff most of the time.

my bro charge his s3 till its full then plug out, so far the battery's fine.

you mean when you plugged in the headset and it autoplays?

i tried a couple of google search queries..
most of them came back as a result of bluetooth? :S

anyway.. try this

1. reboot the phone
2. play a music -> pause it -> exit the music app
3. lock the screen
4. put it in your pocket and see if its still auto playing or not.

if its still autoplaying then

1. open task manager
2. active applications tab
3. kill the music app

if its bluetooth, see if bluetooth is enabled.
maybe you left it on.

if you do that then everything will revert to stock without any custom CWM or rooted device.
so you have to root again using ODIN. then flash your custom ROM if you wish.

erm yes. after that un-root it. (search on xda. )

then go into download mode to check the flash counter to see if its reset back to zero.

if switch from stock to custom -> yes
if switch from custom rom A to custom rom B -> yes
if switch from stock to stock -> no

go to xda developers.
can learn alot.

1. advisable to back up.. (sms and whatsapp)
2. sync your contacts with google contacts so that your phone numbers wont be lost. you may check your contacts at https://www.google.com/contacts/
3. backup your files (images,vids,etc)

after that you may perform flashing.
however, just because you've done flashing doesnt mean its completed.

learn about flash counters, yellow triangle issues (if happen), and learn how to use CWM (recovery).
everything can be absorbed on xda!

no prob. nothing is easy at first.
just take the initiative to learn from xda.

people here can advise, but at the end of the day the phone is yours..
if you really screwed up, there's nothing we can do.

but if you learn the basics of it, you have high chance of preventing it from happening.

16? thats too long
my brother's s3.. rooted + custom ROM only takes about 2-3 hours.

i think your charger has issues.

this one you have to test on your own.

different location reacts to the baseband differently
some locations might be good, some might not.

so its best you test it on your daily route/locations or places you always go..
if the baseband is very weak, move on to the next..

its the only way you can test. so you might have to flash 4 times. (but you no need to wipe, so no worries. just choose a different modem everytime u flash without wiping)
only wipe cache and d/cache!

disable the current one first.
then enable a different type of security lockscreen

did your phone became hot?

why would it be gmail?

i think they should have at least an email with email@samsung.com.my with official helpdesk.

because JB very sensitive liao.. and smooth.

have to get used to it.

PIT?
should be PDA.

go to sammobile.com and download.
that place is much more reliable.

AOSP

did you try to check out http://www.sammobile.com/firmware/?page=3

like i posted few posts back?
if you wanna flash stock.. these are the most accurate and stable versions.

okay. i might have missed this. sorry if i ask you this questions again..

can you see your bootscreen?
and does it end up boot-looping?
