New Mic Mode Controls for WhatsApp Calls on iPhone

WhatsApp has just introduced a new shortcut for iPhone users, with which they can easily access Apple microphone modes during calls. This new feature will allow users to access Apple Microphone Modes directly from WhatsApp instead of opening the iPhone's Control Centre.

Need Advice on which Phone to buy

Hi, I have been an IPhone user for almost 5 years now and I have got comfortable with the device and interface. I am looking to upgrade my I Phone 4S to a higher end phone which will serve my business needs. I mainly use the following applications

• Email (need to review presentations in MS Office and PDF formats)
• Whatsapp
• Skype/Face Time
• Calls
• Camera

While Iphones would be my first choice, I am open to looking at other mobiles. The shortlisted phones are i phone 6, Samsung S6 edge, Note 4 and One Plus one. While my interia from changing from apple is mainly due to comfort level and having a mac and ipads at home. Kindly suggest as i am really confused.
