Does OPPO A57 support small card?

In general, I think that if you are like this one, of course, you will also support this small card.

It's all a small card slot, and the second memory card can be placed.

OPPO A5 will not be stuck for two or three years, and the following is how to reduce the OPPO phone lag:

The more apps we install, the longer we use them, the more and more application caches will be generated, and the memory of the mobile phone is limited, and these cache files will slowly affect the speed of the mobile phone if they are not cleaned up in time.

Instead, free up your phone's memory.

2. If the mobile phone prompts that the storage disk space is insufficient, you can enter the mobile phone manager.

Settings - Application Management - Select Application - Storage Usage - Clear Cache - Done.

Some apps start in the background by default, and even after exiting, they are still running in the background, consuming the amount of traffic wheel buried fingers, pushing ads, and occupying resources, causing the phone to freeze.

How to speed up: 1. Enter the mobile phone manager and set up the auto-start application.

Phone Manager - Permission Privacy - Auto-Start Management.

2. Don't open too many apps at the same time, it is recommended to quit directly after using up, which can not only improve the performance of the phone, but also save power.

Once a mobile phone application is maliciously tampered with, implanted with advertisements or viruses, it is easy to fall into a stuck or serious stuck state.

How to speed up: Go to the OPPO app store.

You can use the phone's built-in phone manager to clean up the phone's memory, or clean up useless files. If it's still too stuck, I can only suggest that you reset it and restore it to the factory, so that it will be as fast as a new phone. The configuration of A57 is really poor, and if the economic conditions are good, it is recommended that you buy one.

It would be much better to clean up the memory and close the background software that you don't use.

Hello, if it's stuck, you can restart your phone.

Take the test to clean up the garbage or reboot it.

It is recommended to clean up your phone junk and give it a try.
