Phones and tablets decrease in performance after a while and even though Nexus devices are superb it does not mean they are resistant from issues. Users will be very happy to learn that the new Android 4.3 update now brings TRIM to all Nexus devices, which includes the 4, 7 and 10.
There were reports of the Nexus 7 experiencing major performance issues last year, the tablet is a masterpiece but it still came with a few issues where a few noticed the performance degrading very fast over a one year period to where in some cases the device was nearly out of commission.
Thanks to the Android 4.3 Jelly Bean update things are about to change, because now it brings TRIM support and this will stamp out the Nexus 7 2012 performance issue.
Actual data is not removed from the storage area when you delete content from the memory, but to the user they would believe it is. If you try to transfer data to the drive yet again it will then overwrite on top of the existing data rather than writing to empty blocks. This is when performance is reduced due to the frequent load up of your storage with content, so TRIM is welcoming and we will explain why.
TRIM basically in simple terms allows the OS to inform the memory, which will block data no longer in use and in return wipes it for garbage collection. If you then decide to transfer data to the drive it will write it in empty blocks, and this is where the word ‘Faster’ comes into play.
The Nexus 4 and 10 were not as bad as the 7 but the Android 4.3 bring TRIM to all Nexus devices will be welcomed to say the least, if you can boost performance then we are all happy. For more in-depth information please visit Anandtech, very useful read.
