I have been using this for past two years or more. This is my life now. I am not interested to change my phone. This is such a nice phone. This is a phone with no hanging problem. The battery backup is very high. More than a day is lasting, even though I am using internet. 4g Lte with VOLTE is available. It has an update upto Android 6. Small and precise. Battery is not removable. Love this.
