Review on Samsung Note 3 , Note 4 and LG G3 D 855

I purchased note 4 on 18th of this month. The experience is good. However following issues observed
1. Only one S note can be opened at a time
2. The screen sometimes goes blank ( white ). Not sure whether it hangs or not

I too an confused with the this buying issue I am zeroed down on Note 3....but i dont know if its good or not.

Previously i was interested on vibe z2 and honor but looking at brand value and also after sales service.
I zeroed it on Note 3.
Please suggest is note 3 better or equal to lg g2 or g3....

It kind of depend on your budget and your needs
Go for Note 4 if price is not an issue but note 3 and note 4 are big then LG G3 should be your choice and price is also affordable and prioritize it over NOTE 3
If it comes between G3 and Note 4
Note 4 is better in every aspect(as it released in later half of year) but G3 is also a good phone and much handy inspite of 5.5 inch screen and speakers are also louder
But If price and handiness is not an issue then NOTE 4 is best better than even Nexus.
Iphone 6+ is also good in phablet dept. but Note 4 is just best...if Looks are necessary then M8 is also a choice(only con is camera)
But among all three mentioned go with NOTE 4..its really a good phone for atleast 2 years
