But this is something that is not entirely clear on all cell phones, in fact there are no native tools that explicitly delete these types of files, except for some manufacturers, for this reason we are going to list the methods we need to find in order to be able to find these updates and remove them in case you haven't already done so.

Check the file explorer

This is the fastest way to find an OTA that has left our phone after installation, although this is rare, to do so is best to open a file explorer app on our mobile which comes natively with our terminal and which was essentially developed by our Manufacturer In application settings, select to view all hidden or system files.

In this way, we guarantee that you can locate the file that initially should be hidden from users so that they cannot tamper with sensitive information such as it contains. You can then search your phone's file system using the search terms "OTA" or "Update ”And even our mobile phone model, for example RMX2170EU in the case of Realme 7 Pro. To do this, consult your phone's internal model, usually the update file contains this name, so it will be easier to retrieve it.

Clear cache

Another way to delete OTA update files is to clear the cache of the phone. For this, it can be done in two different ways depending on the age of our mobile phone. Without Android 8.0 or earlier, we can do the following:

This way, all temporary files on our phone will be deleted, including OTA and system updates if not automatically deleted.In case you have a mobile with a more modern operating system like Android 9 or above, we only have the option to clear the cache via the menu Terminal recovery.To do this, we need to do the following:

Inside we will see several options. Remember that you access this menu at your own risk and improper handling may result in data loss. In all options we have to click on "Clear Cache" which is a function that removes all temporary files from our mobile phone. If when entering recovery, you only see the option of "Wipe Data", it means you cannot delete temporary data of mobile with this method. Not all mobile phones can clear cache this way, but it is available in several. Therefore it is another alternative to be able to delete all this data from our mobile phone, among which are also system updates.

We also have the ability to manually clear the cache of all mobile applications, including system ones. To do this, we need to go to the "Applications" menu of our phone's system settings. To later enter each of the installed applications and access the memory section to clear the cache It is possible that clearing the cache of some installed system applications will also remove all updates in the form of a temporary file which is flooding the phone.

With a native manufacturer tool such as Huawei

This is the least common case, but it does exist, and there is a manufacturer like Huawei that offers us a special tool to remove system updates that have already been installed on the phone. For these phones, the operating system can find and remove the updates so they don't take up more. memory of our phone, for this we need to do the following in the phone settings:

This way, all memory data related to system updates will be completely deleted and won't take up space on our phone.

As you can see, there are many ways to clean temporary files, among which are OTAs, our cell phones, although upgrading the update system and installing it have made this type of update removal tool practically unnecessary as it is normal for them to wipe out. you suspect this is not the case, as you have noticed, there are ways to try and check it.
