iOS 13.4 Causes iPhone to Experience Serious Problems

Specifically, the iOS 13.4 update is showing some errors such as losing characters when searching, in which the plus sign (+) is automatically deleted, making the results returned incorrectly with the user's wishes.

For example, when you may need to search for the price of a Samsung Galaxy S20 + phone, the results show the price of the Galaxy S20 (regular version) because the (+) sign is automatically deleted. This makes you misunderstand about the price, even buy the wrong version.

Another serious issue on iOS 13.4 is that there is a security flaw that could expose a user's personal data to using a VPN because it is unencrypted. According to Proton, when a VPN starts up, iOS 13.4 does not close existing existing unsecured connections, some devices remain active for long periods of time and can remain open from minutes to hours outside the VPN connection..

It is worth mentioning that this error appeared from iOS version 13.3.1. Apple has also confirmed the information, but keeps it appearing on this new update!

Users also responded to many other errors on both versions of iOS / iPadOS 13.4, including third-party keyboard errors on iPad, service error when using Dual Sim, connection error Bluetooth connection, virtual keyboard error, Assistive Touch, function feedback error in Control Center.
