How do I set my SD card as default storage for apps

If it's an android, you can change it within an app - like camera. Go into settings and change default storage location from internal storage to sd card.

If the app can't see your sd card, make sure it's "mounted" within your device. Depending on the software version: Go to settings, general, phone/tablet management, storage, from here you should be able to see the sd card. It is either ejected or mounted. Click on the sd card, if you can see the folders content, then it is installed correctly.

Also, if it was used in another device, it may need to be formatted to be used in your tablet. You can do that from the same setting menu.

Hope this helps.

First, go to Settings > Storage and check if the "Default write disk" is set to "SD card". Then go to Settings > Apps and swipe to the left until you get to "SD card". Below will be all the Apps that can be be moved to the external SD card. Click in the box on the right and another page will come up. About in the middle of the page will be "MOVE TO SD CARD" tab. Tap on it and wait until it finishes. Then go back and pick another App to move. You should be able to download apps directly to the external SD card. I haven't done that on this device and not all apps will download to the external SD card (the app maker can restrict downloads to only the internal memory. This tablet is one of the rare few Android devices that allow moving Apps to external memory.

The default on most tablets is to install apps to internal storage so the SD card does no good by itself. You can go into Settings>Applications and change the location for each app to the SD card. Likewise anything else you put on a tablet, particularly photos and videos get stored in internal storage. If you have taken a lot of photos and videos they can fill up your storage quickly. You can change this in the Camera app by tapping the settings icon and changing the storage option to SD card. You will still need to actually move existing photos and videos to the SD card manually or copy them to external storage and delete them. I would also change the image and video resolution in Camera settings to 640x480. This is plenty good enough for pictures you just want to look at on the device or share online.

Go into app info and click move to SD card. Set your main source of storage as the SD card. Settings -> Storage -> Default storage location.

you need to go into the app management menu and move apps to the card. some won't allow you to do that but many downloaded apps will.

Download Titanium back up. it has all you need you can move all the apps to sd card including built in apps (the ones that can not be unistalled)
Caution: your phone has to be rooted juts google how it can be done in case you are not rooted yet. and be carefull while moving apps some apps can cause damage to your phone if moved to sd card. just move the downloaded ones and some few like photo viewer, galary, music player and the like

This more than likely means your internal storage is low and not the SD card and may not have anything to do with your pictures but more so with your apps. Go into settings and see if your tablet has the feature to set where your downloads and other media is stored, by default that will be your internal memory. change it to SD card or USB storage. In Settings you can also click on your apps individually and transfer them manually one by one to the SD card or USB storage or download a file manager and do so all at once. Some apps and files may not have the feature to transfer these apps the tablet came with or apps you downloaded that uses the internal memory. By default if a memory card is in you tablet pictures are automatically store there, if this is not the case the easiest way to transfer is connecting the tablet to a computer/laptop and transfer to the card or again use a file manager.

One question. Were you able to move apps to the sd card before?
When you go to settings, storage, does it show the external sd card? I want to explain something first. The sd card is an expandable storage card, but it won't store your apps. If you want to check it out just insert the old memory card in a computer and look for any apps. Smartphones usually comes equip with 2 types of storage:
1. Internal phone memory: which could range from 500mb. to 2gb. of storage. This will be by default the location where the apps would be saved.
2. Internal SD Card: this is an expand storage that is already in the smartphone. Notice that when you see an ad for the phone it usually advertise whether it is 4, 8 or 16gb. That is the internal SD storage.
The third option is the external micro sd card, which is the one you are having problem with.
In storage under settings, see if you have an option to mount the sd card, maybe it's not mounted. You can also clon or copy everything from the old sd card to the new sd card using a computer, and then try it again.
