LG G3 Memory Card

LG G3 SD Card

Own a LG G3? Looking to get more storage space on the phone with a memory card? Well, you have landed on the right page, as below I am going to highlight the best rated memory cards for the G3 smartphone.

No need to guess which card is the best fit, as all the options that I look at below are just what your phone needs.

The Best LG G3 SD Card

If you go on any website to buy a memory card, you will see hundreds of options, so how do you know which one is the right one for your phone? Fret not my friends, as below I have listed the 3 best and must-have cards for your LG G3. These cards are chosen on storage capacity, how well they perform and most importantly, price.

If you are a power user and have a lot of apps, pictures and videos on your phone, then it is a good idea to go with a nice 128GB card. You will get an insane amount of space, that won’t be filled up anytime soon and you will also have the peace of mind in knowing that this card will still be relevant 5 years from now. So it is also a good way to future proof yourself.

Do you want that perfect balance of ample storage space and great performance, as well as not being too hard on your pocket? Well this 64GB beast from Samsung is definitely the best option available. You can take hours of video and tons of pictures and not have to worry about filling the card up too quickly and the good thing it works flawlessly in the G3 and it is pretty inexpensive. You cannot lose with this card.

If you find that your phone has an insatiable appetite for data and you feel that you need bigger than 128GB, you can always go with the 200GB option. These cards are not super-expensive, but for the amount of storage space that they deliver, it is really a good investment.

32GB Samsung EVO MicroSDHC Card


If you still want the perfect balance of storage space, without spending too much money, then 32 GB option is a good option to consider. It is half the cost of the 64 GB card, yet it still has a good amount of storage space. Combined with the internal memory, you really should not have a problem with storage if you get this card and you will also save yourself a couple of dollars.

What Type of Memory Cards Does the LG G3 Use?

If you are a novice with buying memory cards, you pretty much would be confused as to what type of memory cards will work in the LG G3. On the market are SD, SDHC, SDXC, MicroSD, MicroSDHC and MicroSDXC. It can be very confusing to figure out which ones to buy, as well as understanding which ones work and won’t in the G3?

To start things off, the LG G3 will only use Micro memory cards. So MicroSD, SDHC and SDXC cards will all work in the phone. No, SD cards will not work with the phone, as they are not the right format and way too big as well. You will often find people using SD cards in cameras and camcorders.

The memory card formats that work with the LG G3 are:

  • Micro SD– This memory card format can hold up to 2GB of music, pictures, videos and apps.
  • Micro SDHC– This memory card that can hold up to 32GB of music, pictures, videos and apps.
  • Micro SDXC– This card can hold up to 2TB of music, pictures, videos and apps.

There is a misconception that I should clear up with the cards mentioned above as people also find themselves confused with MicroSD, MicroSDHC and MicroSDXC. These memory cards all have the same physical dimensions, the only difference between all of them is the storage capacity. The G5 can use all formats with no problems, just that the performance might be a bit slow with some of the older cards.

LG G3 Memory Card Speed

You probably won’t have to worry about memory card speed for your phone, if you get any of the cards that I had listed above. They are all fast enough for the G3 and they deliver the perfect performance for the phone. However, it is still good to know about the different memory card speeds available.

All memory cards all carry different speed ratings. This is the same for SD cards (mostly used in cameras) or MicroSD cards (mostly used in cellphones). When it comes to speed ratings, the main thing you need to know is that how fast a card is determined by the speed at which data can be read/written from the device to the card.

Below are the different card speeds that are on the market.

  • Class 2 – Minimum of 2 MB/s performance. (Slowest)
  • Class 4 – Minimum of 4 MB/s performance. (Slow)
  • Class 6 – Minimum of 6 MB/s performance.  (OK)
  • Class 10 – Minimum of 10 MB/s performance. (Average)
  • UHS-I UI – Minimum of 10 MB/s performance. (Fast)
  • UHS-I U3 – Minimum of 30 MB/s performance. (Really Fast)

Your LG G3 can use cards with those speeds, but if you want high quality performance, then you should not consider any cards under Class 6. While Class 2 & 4 cards will work, you will get annoyed with them very quickly as the phone could slow down when it comes to opening apps, pictures and more. You probably would not be able to record 1080P HD video as those cards would be too slow.

To get the all the details on the memory card speeds, you could always check out the SD Card Association which delves a bit deeper into the subject.

Do I Need a SD Card for the LG G3?

It is a good idea to get a LG G3 SD card, simply because space can get eaten up pretty quickly, even though the phone is available in 16/32GB options.

You need to remember that if you download a lot of apps, take a lot of pictures and videos, the internal memory of the phone can fill up very quickly. This is why it is good to have external storage. So what size memory card should you get for the G3? This is really dependent on how you use the phone. I often recommend that the lowest option you should get is 32 GB, simply because it is a good amount of space and will take some time for you to fill it up. If you are a power user and you will be taking tons of photographs and videos, then the 64 GB option is perfect for the phone.

So what about the smaller cards? If you do not want to spend a lot of money on memory cards, you can always go with a 16 or 8 GB card and it would still serve its purpose. While you won’t have as much space, if you are only taking pictures/video sparingly, then this card could be the perfect fit for you.

At the end of the day, the LG G3 SD card that you choose will really depend on how you plan on using the phone and your storage capacity needs.

How Much Data Can be Stored on the  Memory Card Sizes?

If you read the section above and still not sure as to what size card will work, I think the visual example below can give you much needed insight. In the table below I highlight how much data (music, pictures and videos) you should be able to store on the different sized memory cards.

You should be aware that the numbers used are based on estimates and because of that, the data that you store to the memory cards could be more or less, it really depends on different factors.
