I keep getting insuffiecient storage message

If i may say With out offence, i had a ZTE Paragon and it sucked. As far as memory, ZTE and LG L15G Sunrise sit side by side in lacking memory space. For both devices i got two 32GB sd cards and still no memory then i got two 64GB sd cards and still no memory. The fix sucks, you have to deleat all of your music and any apps you dont use that much. Thats just to download one or two games. The two listed devices are not designed for apps or games rather just the basics of music, photos, text, talk, and lite data. Dump the ZTE as i did and get an HTC Desire 526. I love the HTC i have no memory trubble and i have my own wifi hot spot plus im replacing all my music. Stay frustrated or get upgraded Its your choice.
