What is the difference between an unlocked and a locked 128GB Android phone?

Answers

Unlocked phones work with any carrier; locked phones only work with the carrier they're locked to.

An unlocked Android phone can be used with any GSM carrier, providing you are in a location with cell service. A locked Android phone is tied to a specific carrier. This means you can only use it on the network of that carrier. If you attempt to use a locked phone with another carrier's SIM card, it will not work. You can sometimes unlock a locked phone by contacting your carrier and asking for an unlock code. The unlock code is unique to your phone. The cost to unlock can range from free to several tens of dollars depending on the carrier, your account status, and your phone contract. Whether a phone is unlocked or not doesn't change the phone's storage capacity (128GB in this case). That relates to the internal memory, which holds apps, photos, videos and other data and is independent from the phone's carrier.

Can android recovery programs recover deleted photos and videos?

Answers

Yes, they often can.

Yes, Android data recovery programs can often recover deleted photos and videos. These programs work by scanning your device's internal storage and looking for traces of deleted files. When you delete a photo or video on Android, it isn't immediately erased from the device's memory. Instead, the space it occupied is marked as available for new data. A recovery program can often recover this data before it's overwritten. However, the success rate depends on several factors:

  • Time elapsed since deletion: The sooner you attempt recovery, the higher the chances of success. The longer you wait, the more likely it is that the deleted data will be overwritten.
  • Type of storage: Recovering data from internal storage is generally more challenging than recovering data from external storage (SD card). Internal storage often has more complex data structures.
  • The recovery program used: Different programs have varying levels of efficiency and effectiveness. Choose a reputable program with positive user reviews.
  • Overwriting of data: If you've added new files or apps after deleting the photos and videos, the chances of recovery are significantly reduced.

To recover deleted photos and videos, you'll need to download and install a reputable data recovery program on your computer. Then, connect your Android device to your computer and follow the program's instructions. It's crucial to avoid using your phone excessively after realizing you deleted the files to maximize your chances of a successful recovery.

Remember that not all data recovery attempts are successful. Always back up your important photos and videos regularly to cloud storage or an external hard drive to avoid future data loss.
