CACHE AND INTERNAL MEMORY:If you are an Android user, make sure you clear cache often, manage your applications so that it does not store too much data in phone’s internal memory and refrain from heavy browsing or playing hardware heavy games. This should lead to less crash, especially in low budget hardware Android models with low processor/cpu.
Android application has access that is equivalent to Windows registry style things. Various apps dump garbage and useless things in cache, which fills up phone’s internal storage (like hard disk) and phone becomes slower over time. Even if you install an app in SD card, it still
leaves traces in internal storage space due to android OS design.
