When I bought smg7 grand 2 mobile, the cost of the mobile is 20000.i bought this mobile two and half years years back.the mobile does not give any trouble till one and half years but after that I encountered some problems with that mobile.some of those problems are: ( 1) first of all it is a 3-g mobile, all are using 4-g mobiles today, so it is too old to use this mobile. ( 2) the battery of this mobile is not working as like as it done in the first year.when I use 90 minutes continuously it comes to below 10 % so we can’use it for 2-3 hours.( 3) the next problem is that it is hanging.everyone gets irritate by using this mobile.i won’ suggest these type of mobiles to any one.
