But I want to know whether you want to keep the original Windows operating system. If you install the Samsung SSD in Acer Nitro 5 Spin , you need to install the operating system. Maybe you can clone the Windows OS to Samsung SSD in advance using the cloning tool like CloneGo.

When your storage is insuficient, it may be caused by the following factors: 1. You downloaded and installed apps and kept saving the cache.

And you did the right thing to clear the caches. There are many things you can do: Tip 1: Add a Micro SD card to upgrade the storage capacity. Tip 2: Manage the media content. Tip 3:Delete useless files and messages. Tip 4: factory reset the phone. But you should first backup the data. Yet, of course, you can buy a totally new mobile phone if you have enough money.
