Android OS is very flexible when it comes to customisation and applications, but there are things that can annoy you sometimes when the device freezes, lags or suddenly stops. Being more knowledgeable of the OS, the device and common issues will help owners troubleshoot any Android device.
The common reason why the device suffers lags or freezes is due to overlapping applications that contradict each other. Be simple and eliminate third-party task manage or battery savers. Android can manage what those apps do. Uninstall any recent applications before the problem occurred.
Android core applications stay on your device forever, but there are ways to help you get freedom from bloating the RAM. Android apps such as Maps can be disabled manually. Go to "Settings - Applications - All - Maps". Clear Data, Force Stop, and Disable it. Once disabled, you have to re-enable it to use the Google Maps app. For other applications, you can check their details as well and select the option "Move to SD card," if possible.
3. Speed Up Performance
Try not to stress and push to the limit your Android device all the time even it can. Pushing a device frequently can affect overall performance and stability. If you did something which causes the device to lag at certain times such as use a high-graphics live wallpaper, try choosing another one or stay with still ones. If an app does not work with your device, do not force it. Restart your device frequently to free up memory and get a fresh start.
4. Media and Gallery App failed to read media files
Sometimes the Android media scanner fails to read media files for music and gallery core apps, but the file manager can browse them from the storages. The main reason is the confusing database Android reads such as multiple album thumbnails, leftover images of apps, and more. The best solution is to create a backup of all media files only, not the entire contents of your storages. Format internal/external storage and transfer back the files. Turn off the devices and switch it on, leave it for 5-10 minutes to complete indexing all files.
According to some experts, third-party battery saver apps that are poorly written can worsen battery problems. If you do not know the safe ones, simply adjust your display brightness so low settings would be visible, switch to still wallpapers, use the back key when leaving applications, turn off Wi-Fi/Bluetooth/GPS/Auto-sync when not in use, use Wi-Fi if available than data connection and uninstall apps which eat more battery than expected.
