Have the Lg125DL flip phone and would ask if there a top tier for SD cards for this phone. What is the largest SD capacity as well as best performance for this phone. Guidance sought.
That is a feature phone, not an Android device. We discuss devices running the Android operating system here, not feature phones. Have you asked your carrier or whomever you bought it from?
Welcome to Android Central! From what I found on the web, the largest size microSD card that phone can handle is 32 GB. It's really not going to matter how fast the card is for a basic featurephone. Just get a card from a reliable company like Sandisk or Samsung, and buy it from a well-established retailer (not some random convenience store or eBay seller).
