How is your Edge signal strength??? topic

I was having rather poor signal strength from my Edge. (no more than 2 bars at most) At first I was really concerned that the rooting may have some effect on it?? Or maybe even the quality of my local Vodafone. However after do the following steps....suddenly I get full bars (always):

Go to Setting --> more networks ---> Mobile network ----> change to WCDMA/GSM auto instead of the LTE/WCDMA/GSM

From what I have found, the mobile internet connection is still fast (dont see obvious difference with the LTE) and in fact it seem the battery life last a little longer. I guess I will just keep to this setting.

I need help from someone expert

The notification LED strength changes during charge... topic

I noticed that during charge the LED strength changes without apparent reason. sometimes it's bright red, sometimes it's weaker. same for the green led once charge is complete.
It seems to happen only during charge and only when it relates to the status of the charge. regular notifications seem to be bright.

I have a stock SM-N9005 running 4.4.2.

Is this normal?
