Excellent product, I am using since last 4 months.
Good display
Slim
Good UI
Excellent call qiality
Good battery back up ( Really lasts 1 full day with 4hrs display on)
Only issue I found is:
Some times proximity sensor doesnt works while youre in call. You need to switch off then which is irritating.
Slippery back panel.
Mild hearing issue ( only when your using internet or gaming)
Thank You.
