Everyday tasks. Clear answers.
Connect your TV, print from your phone or put a QR code to work. Find setup instructions, practical checks and solutions for common problems.
Use your iPhone as a Samsung TV remote
Connect an iPhone to a compatible Samsung Smart TV, approve pairing, and troubleshoot discovery with SpaceNode TV Remote.
Connect an iPhone remote app to an LG webOS TV
A practical LG webOS setup guide: same-network checks, on-screen pairing, remote controls and limitations.
iPhone TV remote app not connecting? Check these first
Work through local network permission, TV pairing, guest Wi-Fi and standby problems before changing remote apps.
Use your iPhone as a Roku remote
A compatible Roku TV or player can receive network commands from your iPhone. Navigation and volume are different capabilities: a Roku player is not the same as a Roku TV.
Allow Local Network access for an iPhone TV remote
Local Network permission lets the remote app discover and communicate with nearby TVs. Internet access and Bluetooth permission are separate settings.
Connect an iPhone TV remote using a TV's IP address
Manual connection is useful when a supported television is reachable but absent from discovery. It requires the TV's current local IP address and the correct brand.
Type on your TV with an iPhone keyboard
An iPhone keyboard can help with searches on compatible TVs, but the active TV app and input field must accept remote text commands.
TV remote app connects but volume does not work
A successful connection does not prove the app can control the active audio output. TV speakers, a soundbar and a streaming player can each use different volume paths.
Why an iPhone remote cannot always turn a TV on
Turning a TV off and waking it from standby are different operations. A network remote needs the television to retain a reachable network or supported wake capability.
Lost your TV remote? What an iPhone can and cannot do
Your iPhone can replace some controls on a compatible TV that is already connected to your network. Initial Wi-Fi setup and pairing approval may still require physical controls.
How to print a PDF from your iPhone
Print a PDF with built-in AirPrint or Smart Printer, choose pages and copies, and check the preview before printing.
“No AirPrint Printers Found” on iPhone: a checklist
Check AirPrint compatibility, network access and printer readiness when your iPhone cannot find a printer.
Print Google Drive files from an iPhone
Make Google Drive available in the iOS Files picker, open a document in Smart Printer, and print with AirPrint.
Print photos from your iPhone without unexpected cropping
Choose the original image and inspect its paper preview before printing. A photo's proportions may differ from the selected paper, causing borders or cropped edges.
Scan a paper document and print a copy with your iPhone
Use your iPhone camera to scan a page, review the resulting document and print it through AirPrint. This is useful when your printer has no convenient copier controls.
Print a webpage from your iPhone with a readable layout
Webpages can produce different printed layouts from what appears on screen. Preview the printable content before using paper, especially on pages with menus or long comment sections.
Print an email attachment from your iPhone
Print the attached document itself when you need an invoice, ticket or form. Printing the email conversation may include headers and omit the attachment's full pages.
Print only selected PDF pages from your iPhone
The iOS print sheet may let you select a page range instead of printing the whole PDF. The preview's page order is the reference, which can differ from printed page numbers.
Print double-sided from an iPhone: check printer support
Automatic two-sided printing requires a compatible duplex printer and an option exposed in the iOS print sheet. Installing a printing app does not add a duplex mechanism.
iPhone says printed but nothing came out: check the print job
Sending a job is different from a printer producing paper. A sleeping printer, paper mismatch or an existing queue can delay a document after the phone submits it.
Create a Wi-Fi QR code on your iPhone
Make a Wi-Fi QR code with the correct network name and encryption, test it, and share it with guests.
Export QR and barcode scan history to CSV on iPhone
Export saved codes from SpaceNode QR Code Scanner to CSV, understand the columns, and open the file in a spreadsheet.
Scan a QR code from a photo on your iPhone
Read a QR code from a saved image, check the decoded result and troubleshoot blurry or cropped codes.
Create a website QR code on your iPhone
A website QR code opens the URL encoded inside it. Use a complete public address and test it before adding the code to a poster, package or business card.
Create a contact QR code for a business card on iPhone
A contact QR code shares structured details such as a name, phone number and email. The receiving phone still controls how those fields are shown or added to Contacts.
Create a plain-text QR code on iPhone
A text QR code carries a short note directly, without requiring a website to display it. Use it for simple instructions or labels that should remain readable without opening a link.
Create an email QR code on your iPhone
An email QR code prepares an email action for a compatible reader. It does not send a message automatically or guarantee that a mail app is configured on the receiving phone.
Create a phone-number QR code on iPhone
A phone QR code lets a compatible reader offer a call to the stored number. The person scanning remains in control of whether to start the call.
QR code not scanning on iPhone: image or link problem?
First distinguish a code that cannot be decoded from a decoded link that will not load. Camera focus and contrast fix the first problem; website access is a separate issue.
Create a QR code for a restaurant menu on iPhone
A menu QR code usually points to a webpage or public PDF. Host the menu first, then encode its address; creating the QR image does not upload or host the menu for you.
