So my Samsung Galaxy Y unexpectedly turned off yesterday. When I try to turn it on it just turns on until the Samsung Galaxy Y GT-s5360 or the welcome screen but turns off again so I tried three times before it turned on. I was able to use the phone for like 5 minutes then it turned off again and from then on I can only turn it on until the Samsung Galaxy Y Welcome screen for 5 seconds only. Take note only 5 seconds or less than 10 seconds. This is not boot loop I am sure for the phone turns off. When I try the volume up + home button + switch button I cannot do anything with it since it turns off in less than 10 seconds. I've been asking around other sites and people told me that this might be because of the internal memory and I think they are correct because my phone has been saying internal memory almost full but I simply uninstall apps. But if this is true then how am I able to delete files if I cannot even access my phone. I dont wanna go to a technician and have it reformated because I would be paying much and I have important files that cant be deleted. Please help me. I need your reply thanks.
