معرفی و بررسی Clean Master

با زیاد شدن حجم برنامه ها در تلفن همراه، به مرور زمان سرعت عملکرد دستگاه پایین می آید. این مشکل به دلیل فعال شدن سرویس هایی است که برخی از اپلیکیشن ها در پشت پرده انجام میدهند و شما آنها را نمی بینید. همچنین بعضی از این برنامه ها برای انجام وظیفه خود، فایل هایی را در پوشه های مخصوص ذخیره میکنند که پس از مدتی کارایی لازم را نداشته اما همچنان در حافظه باقی خواهند ماند. این عوامل سبب میشود تا علاوه بر پر شدن فضای موجود بر روی گوشی، حافظه رم نیز بیشتر اشغال شده و سرعت آن پایین بیاید. برنامه ای که در ادامه و تحت عنوان “Clean Master” معرفی میکنیم، در این زمینه مفید واقع میگردد. برای آشنایی با این اپلیکیشن اندرویدی، همراه ما باشید.

سلطان مدیریت حافظه در اندروید!

یکی از مشکلات مرسوم گوشی های اندرویدی (دوستان iOS باز از این مشکلات ندارند!) کمبود رم است، بعد از مدتی کار کردن با گوشی و نصب اپ های مختلف روی آن و افزایش سرویس های فعال،به تدریج سرعتش کمتر و کمتر می شود و گاهی هم کلافه کننده! البته این مشکل به علت ساختار خود سیستم عامل اندروید کاملا قابل حل نیست ولی به جرأت می توان گفت که Clean Master بهترین راهکاری است که برای مدیریت حافظه وجود دارد.
