LG K31 Rebel Screen Mirroring, Miracast, Cast to Roku TV

LG K31 is a budget phone with an underpowered Mediatek Helio P22 processor. For a smooth screen mirroring experience without a frame drop, we need at least a mid-range processor such as Snapdragon SDM 450 found on K40.

Moreover, for screen mirroring, the phone should be Miracast enabled. Let’s see if there is the Screen Casting option on LG K31 or not –

LG K31 Root, Bootloader Unlock, TWRP lmk300qm Rebel l355dl

In the earlier days of Android, rooting was quite easy. It was possible to root the phone via one-click rooting apps without using a computer.  I rooted my LG Tribute 5 in a single click even without unlocking the bootloader.

However, nowadays we need to follow the long path. To root my LG K20 plus I unlocked the bootloader, installed a TWRP custom recovery, and then flashed a Magisk/SuperSU root file via TWRP.

Let’s follow the same procedure for LG K31 as follows –

LG K31 Move Apps to SD Card – Rebel l355dl lmk300qm

LG K31 is an entry-level Android 10 smartphone. It comes with only 16GB of internal storage space. More than half the storage space is used by System memory & pre-installed apps.  We are left with less than 7 GB of actual usable space.

To cater to this problem, we can use a Micro SD memory card. However, the apps and games will still eat up the memory as they are installed in the internal storage.

To fix this issue, we can move the apps & games to the SD card and make it the default storage space. This feature is known as Adoptable storage. We need to partition the SD card as internal storage.

Let’s see how to move apps to SD card on LG K31 as per the below video & screenshots –

Before moving apps to SD card on K31, make sure to

  • Backup your internal storage data.
  • Use a high-speed micro SD card. At least Class 10 is preferable.
  • Keep the SD card inserted all the time. As apps will install on the SD card, removing it will show app close errors.
