This is the first thing you should disable if you buy a Samsung or Motorola phone...it will cause your phone to fail.
Mobile phones have many useful features, but some are rarely used, exist solely to distinguish themselves from competitors, or exist simply because they appear appealing in theory. This is the case for virtual memory.
If you have a Samsung, Motorola, or other smartphone with a virtual memory feature, the first step is to disable it. The reason is that it provides almost no benefit; in most cases, it slows performance and puts additional strain on the device's components.
The term "virtual RAM" refers to using storage memory as RAM. This is what attracts manufacturers, who advertise phones with 16GB of storage, then specify in the fine print that they contain 4GB of RAM and 12GB of internal storage.
Virtual memory problems
It is a technology that has existed for decades on personal computers through specialized applications, and the fact that almost no one uses it is evidence that it does not give good results.
The first limitation is that if the storage memory is used as random access memory (RAM), it will be temporarily unavailable for data storage.
But the main problem lies in the enormous speed difference, even with the fastest types of storage available. As Make Use Of explains, UFS 4.0, currently the fastest, reads data at 4200 MB/s and writes at 2800 MB/s. Meanwhile, LPDDR5X RAM transfers data at 10.7 Gbps, or 10700 MB/s. That's five times faster.
There's another detail to consider. The fastest storage types, UFS 4.0 or 5.0, are only found in the most expensive phones... which typically have significantly more RAM and, therefore, don't require virtual memory. In contrast, the phones that get heavily marketed are usually mid-range or low-end devices with much slower UFS 2.2 storage, resulting in worse performance.
The problem is that using storage as random access memory (RAM) significantly slows down application performance. Its use is rarely worthwhile.
In fact, apps are designed to consume as little RAM as possible because developers want them to run on as many phones as possible. Furthermore, Android manages RAM very efficiently, so in 99% of the apps you use, you won't need virtual memory.
How to disable virtual memory on a mobile phone
Not to mention that this technology constantly writes data to the internal storage unit, which will cause it to become corrupted faster.
In short, my advice is that if you have a mobile phone with a Samsung RAM Plus function, a Motorola RAM Boost function, or a similar function, you should disable it.
On your Samsung phone, go to Settings, then Device Care, then Memory & Additional RAM. After disabling it, don't forget to restart your phone.
On your Motorola device, go to Settings, then System, then Performance, then RAM Boost. Restart your device, and you're good to go.
Virtual memory can be useful in specific situations, for example, if you want to test a game that requires 8GB of RAM and you only have 6GB. However, for 99% of applications, it's unnecessary and may instead lead to performance slowdowns, increased battery drain, and damage to device components.
