Smartphone slowing down or low memory warning message




symptom Symptom


             When the smartphone’s data memory (eMMC  / ROM) or RAM used for managing apps becomes

             insufficient, running too low in fact, the smartphone risks slowing down and/or be subjected to an

             error message notification popping up on screen to that effect.


concept Concept


             A main memory in a mobile device consists of RAM and ROM.


             1. RAM (Random Access Memory)

                 ① Used to read and write data.

                 ② Go to Setting > Apps > Running to check RAM.
             2. ROM (Read Only Memory)
                 ROM is the memory storage that maintains stored data without any external power source.
                      It plays the role of a computer hard disk drive (HDD) in the phone. 
                 ② Please go to Setting > Storage > Internal Storage > Available. 
                 ③ Apps are stored in ROM. Smaller the ROM, the less apps can be stored. To write more data,
                      an external SD card needs to be used.
                      To manage your memory space, go to Menu > Settings > Apps > select the App > Uninstall

                      or move to the SD card to manage memory.

                       Some apps may not be stored in the SD card.

                      Used) to activate Low Memory Killer (LMK).

             1. Message “Low Memory” pops up and the phone slows down

                 Please uninstall apps to secure space on the phone or move them to the SD card to secure

                      them to memory.

                 ② Go to Menu > Settings > Apps > select the App > Uninstall

                      Or, move them to SD card to manage memory.

                      Some apps may not be stored in the SD card.


             2. When the phone slows down or an error message pops up due to lack of RAM

                 ① When running apps that require ample memory space, less frequently apps that are running in

                      the background get closed by Low Memory Killer to secure space. It may appear as if it is taking

                      more time to run the app on account of this process.

                 ② Also, when an app gets opened while available memory is insufficient it will also take some time

                      to secure some memory. 
                      Using the Home key to exit an app without closing it properly can also make the app uselessly

                      taking up RAM, thus slowing down the phone.

             3. How to secure RAM

                 ① Please use the Back key (memory) to close an app, instead of the Home button.

                 ②  Menu > Settings > Apps > Running > Select running process > tap stop

                 ③ Close running apps among those pre-installed on the phone such as App manager. 
                      Pre-installed apps may differ by model.

                 ④ Install Task Killer from Play Store. It will help to you close apps manually.
