I have been using this phone for 2.5 years. Due to an accident, the back shell and glass got cracked. If the brightness is kept at 50 or higher, the display looks fully fresh; if kept lower, it flickers. Those who want to use it after servicing can take it. The original charger is still available. Of course, you will have to come to the location. Gopalganj Sadar, Jalalabad Union, Ejoler Kiyat.
