I've got an LG Bello 2 X-150 with Android 5.0.2 and a 32 GB SD card. In Android 5.0.2 you can't install apps on the SD card which of course sucks. I have tried to work around this by rooting the phone using KingoRoot as described in
https://www.kingoapp.com/root-tutorials/how-to-root-android-5.0-5.1-lollipop-with-root-apk.htm

Then I changed the install location as described in
https://www.quora.com/How-can-I-install-apps-directly-to-an-SD-card-on-Lollipop-without-rooting

Both things seems to have worked. When I type "pm get-install-location" in the terminal it returns "2[External]" as it should. However, when I try to install apps I mostly get the message that there's not enough space on the device, although space both on the internal memory and the external SD card should be sufficient for the installation. I have managed to install one app, but I suspect it was installed on the internal memory, since the amount of availiable memory on the SD card didn't change at all.

What to do?

 

I'm trying to install apps from Play Store. I guess I'd better read up on what an "adb install" is... Thank you for the advice!
