I started to use Digi prepaid last week and I experienced this problem also. 3g sometime drop, signal bar quite ok( 3,4, full liddat). 3g won't reconnect unless Airplane mode or reboot? =.=?  Digi problem or note 4 problem hmm

Digi users help!

So can conclude DiGi network causing it or maybe all of the Note 4's have some compatibility issues with DiGi.

your sim card is cut one?

Oh .. cos some forumers suggested earlier. A cut-sim card could be the problem causing the data.

I forgot to replace mine. :\

haha..my bad...i was confused with oppo packaging....so nobody here face the charger adapter problem? i think maybe it is cause by the defects in batches of the phone.....

i'm using Digi, the old data plan that RM68 for 5GB per month if you want to know too.
my area usually get max 3G/3G+ or 2 bar 4G.
Incase u need my disable list too:
Google Chrome,google+,books,games,music,newsstand,s voice,voice search,dropbox,
samsung link,hp/samsung print service,hancom,yahoo live weather

Don't mind it,lol...
i bet it's the same just when i change that time have a promo for 3+2GB,which is great not like current 78 2GB+1GB apps data 
Just head to any digi center exchange the new black colour Usim then u can get 4G on the spot.
*Exchange fee were RM10 *

*edit*
you don't need to upgrade new plan,just change the old sim to new 4g sim*black color*,that's what i did,no upgrade or change plan.

I'm using DiGi and changing your old SIM to LTE ready SIM will not effect your current data plan package.

Yea same. No LTE too. Are you going to replace your sim card? Tell me if it works. 

Did they charge you for that?

Yea man, hopefully is the telco's fault. 

Time to change sim.. Do they gave you the 4G/LTE sim?

i second that. Mostly hardware improvement. I also came from Note 3 and i consider this as a huge upgrade. Especially the camera

in my case S2 to Note 4..is like a leap of faith...

NOte egde is just a fashion statement now..nothing big with that phone. .almost same with note 4 with extra lcd pixels and curved screen

Send to LowYatt lunch hour send, after work can collect jor.

My Note 4 barely touch 1 day

haha, i wish 1 to 1. Anyway my phone less then a month old.

Never know note 4 battery life so bad

Hopefully few cycle the battery will get better.

Hopefully will get improve. BTW i only use lots of whatsapp. So no email or FB  on my phone.

Yes WAC

Sorry. Whats art?

lets hope they don change what is not broken
