Hi! I'm sorry to hear that you're experiencing issues with your Infinix phone. Here are some possible solutions you could try:
1. Restart your phone. Sometimes, a simple restart can fix minor software glitches.
2. Check if your phone's screen is dirty or has a screen protector on it. If so, try cleaning the screen or removing the screen protector.
3. Try calibrating your phone's touch screen. You can do this by going to Settings > Display > Touchscreen calibration.
4. Check if your phone's operating system is up to date. If not, update it to the latest version.
5. If none of the above solutions work, you may have a hardware issue with your phone's touch screen. In this case, it's best to take your phone to a certified repair shop or contact Infinix's customer support for assistance.
I hope one of these solutions helps resolve your issue!
