to the SD card if the app allows for it. Its simple enough for you to do it without much worry.
There are two things you need to be aware of with moving apps to the external storage. First, these apps wont work when you connect your phone to the PC and switch on storage mode. Second, the widgets of any app will not work when moved.
So are the Moto E, Micromax Unite and others useless?
Not at all! They are just limited in what they can be used for, and its important to know this limitation because thats how you can decide whether such a phone is for you or not.
If you are someone who likes to try out new apps, play a lot of games, use several widgets, or are a general power user, then these phones are not worth it for you. They just wont deliver the experience you are looking for.
If you are someone who just wants the basicscalls, SMS, email, WhatsApp, browsing, etc.then the 4GB limitation is something you probably wont mind because you are unlikely to install enough new apps or games to be affected by it. However, do note that every 6 months or so, you will see an error saying you are running out of storage space. Dont worry though, this is usually just cache built up on your phone, so run have to clean your phones cache. Its easy to remove that junk with 1Tap Eraser. And if the problem is still not solved, run DiskUsage to see whats taking up the most amount of memory and delete it.
