Phone got some problems like with illumination light (notification led) and camera within a week, when I visited service centre they said it's a software problem but after updating also phones problem doesn't solve, but my phones replacement period was over so I wasn't able to replace my phone so I have to use the same, but when problem increased I visit again service centre at 27th February (W[protected] and return my phone at 2nd March but problem wasn't solved. So I went service centre again when it causes too problem at 16th June (W[protected] and they returned phone next day but still problem wasn't solved, so I've to visit again at 24th June (W[protected] to service centre they replaced motherboard of phone but still problem wasn't solved and they return phone at 29th June, then they suggested to replacement of phone so I submitted my phone at service centre at 3 July (W[protected] and they gave me replacement at 31st July finally, but that phone also was unable to update so they demand again my phone to submit and I have to submit it at 8th August (W[protected] and they replaced phones motherboard again and gave me phone at 7th September after a month.
