I agree that an USB OTG adapter would give greater flexibility for storage of pics, vids, and music, and it's a good suggestion in most storage issues. I have several USB OTG adapters and the work great. However the OP was apparently more concerned with the limited number of apps they could install. Unfortunately there is little to nothing an OTG adapter can do in this case to assist in that. Less than 50MB of data can be moved off giving little additional space for apps.You can also get an "on the go " memory card. Search for them on amazon. Reasonable price. Lotsa storage
