I brought this phone 9 month back.
Ever since I purchased this phone I have observed following so many issue related with this phone.
After normal use for 2 months, it was started showing  Sim 2 not detected error message  I thought it is a network issue but unfortunately after 3 month, Sim2 stop working.
Memory card detection I was using 32 GB Samsung high end  memory card, after 4 month it stop detecting
Phone randomly restart automatically.
Fast charge technology is fake.
Do not buy this phone buy some others.
