Hi. Today I tried to download an app from the play store that was only 30 MB. It told me that I had Safficient Storage available. My SD card has 6 GB available and It says that I haven't enough storage. I reseach it and I found that I need to clear the cache. My cache is around 700MB's. I'm not sure If I need to clear it but I want to solve the storage's problem. If I clear the cache will I lose anything? Like photos, music, apps data? (Do I need to log in Facebook,Instagram) for example after the cleared cache? Also if I clear the cache will it slow down my apps, or even the phone? Or the opposite will it speed it up ?
