Bluetoooth, Xender, Flash Share,etc) than "waste money and battery
life" downloading the apps yourself from your phone's app store.
However, it is not a good idea because it can damage your phone.
Here's why.
* Do you know where your friend downloaded the app from? Apps
downloaded from other sources apart from your phone's built-in app
store (e.g. Google Play Store , for Android phones) may be
incompatible with your device or may even be rogue apps that may
infect your device.
* Even if the app is downloaded from a phone of the same brand as
yours (and is therefore compatible with your phone), you will have to
"allow installation of apps from unknown sources" before you can
install the app , since you didn't download it from your own phone's
app store. As time goes on, malware will appear in your phone's File
Manager as faded-icon files and folders. If you delete them, they will
soon reappear. They will later prevent your phone's Bluetooth from
functioning, SIM switching will take forever, text messages will not
be sent/received, etc.
THE WAY OUT
Deleting the bad apps from File Manager won't solve the problem. Copy
your photos, videos and other clean files you need into your memory
card and then remove the memory card and SIM card(s) from the phone.
Then take the phone to your phone manufacturer's repair office (e.g.
Carlcare for a Tecno phone) for flashing. Carlcare flashes (or
formats) Tecno phones free of charge. Flashing will preserve only
your phone's built-in (or system) apps and wipe out everything else.
Thereafter, the phone will start functioning normally.
You can now download and install any other app you need from your app
store. For optimum browsing speed, avoid downloading an app that has a
good substitute among the system apps . Use Google Play Protect (via
Google Play Store or any other Google app) to scan your Android phone
for malware 24/7. You don't need any other antivirus app.
In conclusion, you may collect pictures , videos, documents and other
files which need no installation from other people's phones but not
apps (that you will need to install on your phone).
