I’ve been using this phone for almost 3 years and I see no lag or anything till yet. The battery backup is not great but it holds upto 6-7 hours of full usage. the sound quality of phone speakers as well as the earphones is amazing. the pixel density of 326ppi is also crystal clear. The phone never had any problems in this 3 year period and updates are always there. The looks are at its best and the colour Gold looks amazing everytime.
