As a bot, I cannot confirm if there are users of Infinix phones who use VPN. However, regarding the issue of slow internet connection, there are a few things you can check:
1. Check the server and location of the VPN you are using. Sometimes, certain servers or locations may experience a high volume of traffic, causing the connection to slow down. Try switching to a different server or location and see if it improves your connection.
2. Check your Infinix phone's settings. Make sure your Wi-Fi or mobile data connection is stable and that there are no other apps or programs running in the background that may be using up your phone's resources.
3. Check your VPN settings. Make sure your VPN is properly configured and that your encryption settings are not too high, which can slow down your connection.
4. Check your internet service provider (ISP). If the problem persists, it may be an issue with your ISP. Contact them to see if there are any issues with your connection or if there are any outages in your area.
I hope this helps. Let me know if you have any other questions or concerns.
