It is important to do this correctly, otherwise the smartphone will stop working. Often, with such problems, the smartphone starts to freeze during a call.
Due to the liquid that got inside the case, the smartphone can slow down considerably when loading. Sometimes it doesn't turn on at all.

Attention!
When the phone or tablet starts to slow down - applications start more slowly, there are delays when flipping through screens or when switching between items in the menu - this starts to strain and even annoy. And if this happens at a time when you need everything at once, then you want to smash the phone against the wall.
Performance degradation is a problem that we face not only on phones. Brake after prolonged use begin and personal computers and laptops, this is normal. Good news The fact that the speed of Android can be restored.
Think back to when you first bought your Android smartphone. It also slowed down and buggy when executing simple actions? If not, then we will try to return the former performance to your phone or tablet.
So, the first step you need to take is to review all your applications. Each installed application takes up space in the system and therefore negatively affects its performance. Feel free to delete app if you don't remember the last time you used it! After all, re-installing the application, if necessary, will take only a few minutes, and deleting unnecessary applications will speed up your Android device and possibly save your nervous system 🙂
The second step to cleaning Android smartphone or tablet will clean up the device from debris.
Go to the gallery and view media files, delete unnecessary photo and video files. In the gallery, before deleting, you can review all the files so that you do not accidentally delete what is really necessary.
Go to the downloads, usually a whole bunch of unnecessary garbage is also collected there, because of which Android slows down. Look through the files in the downloads and delete what you don't need.
Go to settings and select the "memory" section. Here we are interested in the item "Cache" or "cached data". Cache is pre-loaded information into the device's memory. different applications- e.g. gallery thumbnails, splash screens, application media files. This data in large volume can also slow down the device. Therefore, boldly click on this line and confirm the clearing of the cache.
In the “Memory” section there is also an “Other” or “Miscellaneous” item, you need to be careful about cleaning it, you can go into it, but if you are not sure whether to delete any of its items, then it’s better to leave everything as it is.
We go further - a memory card. A lot of unnecessary files are also collected on the memory card during active long-term use. The system takes longer to scan them, which slows down your Android phone or tablet. 
Cleaning the memory card is best done with backup data. To do this, if the computer or laptop has a card reader, then turn off the Android device, then remove the memory card and insert it into the computer. We create a folder on the computer disk and copy all the contents of the microSD card of our Android device into it. After copying, check if everything was really copied, this can be done by comparing the size of the information on the SD card with the folder that contains the copy.
Next, insert the memory card into the Android device and turn it on. The following steps will To complete removal all data from the memory card. We go into the settings, the memory item, look for the line "Erase memory card" or "Erase SD card" and start cleaning.
None of the above helped? Well, there is still the most radical, but at the same time the most effective remedy. You may have heard its names such as Wipe (wipe) hard reset (Hard Reset) full reset Android, general reset Android, factory reset Android. All these names reflect the essence of this decision - a complete reset and return Android to the state when the phone was turned on for the first time. All data that was on the Android phone or tablet will be irretrievably destroyed!
As a result of an Android hard reset, all photos, videos, applications, Accounts, contacts, so before executing it, make a copy of the necessary data!
So, if, nevertheless, Android got it so that a full reset is the only way out, then we do the following: Go to the settings, go to the restore and reset item, select "general reset" or "factory settings", scroll down the screen, put a tick on the item " Clear internal storage” and click the “Reset phone settings” button.
Even if after full reset Android phone slows down, then maybe it's just outdated and no longer meets your requirements, it's time to change it! 🙂
To evaluate the performance of the phone, there are special applications, for example. Install and run this application and test your Android device, if your faithful friend scores less than 6000-7000 points in the test, then you should seriously think about a new device. 
When choosing a new device, it is desirable that it score at least 15,000-20,000 points in Antutu, this is a necessary minimum for comfortable work and launch most games. But that's a completely different story.
I hope these tips will help speed up your Android and save readers a nervous system 🙂
