The software version is already quite old, but I have been using it; it takes up very little RAM. I tried the new version and it uses over 300K RAM, whereas this version only uses just over 100K. As everyone knows, low RAM is a hardware limitation of the fifth-generation phones…\The new version is too resource-heavy, this version is only just over 60K, it can't be streamlined any further, and it has basic functions. You can also DIY unlock it yourself, but it's just a bit troublesome.\

\【I personally took the screenshots, and you can see the effect. Absolutely practical and aesthetically pleasing. The only drawback is that the unlock background can only be set to one; if you want to change it, you have to reset it.】\
