My tab is stuck on "Samsung galaxy tab 4" logo its showing this logo and turning off again. It's been 12 hours it's the same. How to fix it? I've tried it power n volume down option too and that safe mode option too. Nothing is working. What would be it's problem? Will I have to change the battery? ( it's been more then 2 n half year to my tab. It was working absolutely perfect till yesterday. Please tell me it's solution as soon as possible. Last year I was having this problem but by pressing power n home button it was solved but this time nothing is working. waiting for your reply..
