As the title says, I can't find the option to Format as Internal Storage the sd card in my phone. My phone is a Samsung Galaxy J2 Prime and I need to do it because I wana download large apps on my phone the 1 gb plus apps, reason is I have 8gb internal storage and like its already filled up with 6 gb system memory, I had like 4gb/8gb to start with then overtime it became 6gb/8gb without, and literally without downloading anything. Can anyone tell me how do I make my phone make the sd card its internal storage? I just want to download this game's data to the sd card but it won't fit in the freaking internal storage. Please help. Thanks.
