Nope. I think i have found the problem. It is on my memorycards ... 64GB SandiskUltra. Yesterday night the batery was drained to almost zero and when in the morning i charged it and started it was acting weired ... was showing memorycard has storage issue ... but the card is 30Gb full .... Now it is acting weird ... doesn't start the phone having card on it. i tried o access the card from Card slot of my laptop ... it is super slow ... ! What should i do ? I have many valuable data on that !
