No removable battery, No Memory Card = No Sale
I have had every version of the Galaxy Note to date + various other Samsung 'phones (inc S3) & tablets.
I rate the Note 4 very highly; I had thought of trying an S6 pending availability of the Note 5, but in the light of the above I will wait for the Note 5. However if the Note 5 doesn't have an SD card slot & removable battery then I won't be buying it.
With all my Notes I have bought a spare battery & charger/case, and rotated two batteries as I am often in situations where one is travelling light, and cannot access a recharging facility for a day or two.
Likewise I want data stored on a removable card which can be backed up, not on a 'phone which can be lost or damaged.
Does Samsung listen to it customers - it seems not.
