So, I had tried rooting the Galaxy Tab A SM-T510 recently with twrp and after installing the twrp the internal storage has gone messed up. -17 gb?? Out of 4 gb? My Tab A has an internal storage of 32 gb, but after rooting it has changed to 4gb and i can’t do anything. I can’t download apps, nothing. If someone knows what to do, please let me know.
