事情是這樣的
小弟最近迷上了修改build.prop
於是開始上網google相關的文件
也實際拿自己的小P來做測試
測試結果效能好像有提升
例如手機上網速度變快、看1080P的影片不會LAG
不知道是心理因素還是什麼...
附上我修改的build.prop
有興趣的大大可以一起來研究XD
由於是在網路上找到後就直接寫進去
也沒注意各個程式碼是屬於什麼類別的
所以程式碼的排版有點亂還請見諒...
P.S 由於小弟剛接觸這塊，所以不是很確定哪些有效果哪些沒效果，還請各位大大多多指點...
以下為我修改後的build.prop的內容，會使用的也可以直接拿來做測試
補充: 我的手機狀況是未解鎖 已ROOT 已刷BE2 如果有刷BE2的可以直接拿來做測試
沒刷BE2的把程式碼後改回來即可做測試
