Increase Available RAM on the Galaxy Y
One of the worst things on certain budget-friendly smartphones is not having quite enough RAM. This normally isn’t a big deal for many users who use their phone for the practical purposes of calling people, sending texts, and checking email. However for people who do a lot more with their devices such as gaming and heavy app usage, the shortage of RAM may be a bit more limiting. Running out of RAM can cause a lot of problems such as app crashes and large-scale lag.
While you would have a hard time physically soldering on more RAM, users of the Samsung Galaxy Y can enable a swap file and partition thanks to a method written up by XDA Senior Member CarlDeanCatabay. This is similar to the pagefile used in windows, and while it isn’t nearly as fast as RAM, it may help certain apps that require a bit more breathing room.
The method is a little complicated, and requires you to repartition your SD Card. This method will also potentially lower the lifespan of your SD Card due to the higher number of write cycles. As the process is pretty general, it’s not impossible to port this method to other devices by simply modifying the required files to work with them.
