## Customer Reviews

### ⭐⭐⭐⭐⭐ Good delivery
*by L***O on November 2, 2024*

The service and delivery from Amazon was great, but before I installed this on my Galaxy a14, the phone got knocked into the water and the motherboard got messed up beyond repair.IF YOUR SAMSUNG GALAXY A14 GETS KNOCKED INTO THE WATER, TURN IT OFF RIGHT AWAY! BRING IT TO A REPAIR SHOP BEFORE YOU TURN IT BACK ON.

### ⭐⭐⭐⭐⭐ It's Mostly a Good Buy
*by D***N on January 16, 2025*

This battery replacement is good and it came 60% charged, even after waiting almost 3 weeks to install it ! It came with so many tools! When i opened the box I wondered why there were so many extraneous tools to do this job.BUT what it didn't come with were instructions! I guess everyone uses YouTube to figure this out nowadays and that is what I did.Changing a cell phone battery is not like the old days where you just open the back of the phone, pop the old battery out and put a new one in! There is a process! And the myriad of assorted tools were necessary to accomplish the task.The adhesive strips are precarious, but once I figured them out, they worked OK. Won't really know until I have to change the battery again, which I don't really intend to do, as it would be time to get a new phone by then!Overall, for the price versus getting a new phone, I would recommend the product.

### ⭐ Battery is new and overheats
