Why I'm having notification led problem in samsung galaxy s5.

[Siddharth chandarana]

The notification led stays constant if it not charged and different colours pop out. Like i have selected green colour for whatsapp but it shows blue colour or sometime purple. Why this is happening? I'm having trouble from past five days.
Thanks.

Seems to be a Whatsapp issue. See, LED colour notification option on whatsapp?

Try choosing a different colour.
