Q: in my iphone 5 app store unable to update apps any solution

Hi Ayazkiyani,

If you can't update apps try these steps:

• Make sure you're running the latest iOS version
  • Open Settings > Tap General > Tap About > Tap Software Update
    • If you're running the latest iOS version, you'll get a message saying "Your software is up to date."
      
• Make sure you're on a wireless connection.
  
• Reset your network settings
  • Open Settings > Tap General > Tap on Reset > Tap Reset Network Settings
    • If you're prompted for a passcode, go ahead and enter it then follow the remaining onscreen instructions.
      
• Sign out of iTunes & App Store and iCloud
  • Sign in with a different Apple ID on your iPhone, iPad, or iPod touch  - Apple Support

I hope this helps,

John
