99 Problems But Your Old Nexus Shouldn't Be One

Anthony Muzonzini

Out of the box, the first generation Nexus 7 was actually very fast for its time. It produced pretty decent graphics also but after some time users began to see a downgrade in performance. It then probably gets so slow that users wipe everything on the device and start afresh. The cycle then repeats itself again.

The old Nexus 7 Problems fixed by Android 4.3/ © AndroidPIT


It seems that the first generation Nexus device suffers from a storage I/O aging problem whereby when the owner of the device deletes something like a video file or removes an app from the device, this is not communicated directly to the eMMC controller. Because of this it still treats the page in NAND as if its still holding data even though the blocks are no longer in use. fstrim solves this problem by sliding in between the eMMC controller and the operating system and it communicates to the eMMC that certain blocks are no longer in use and they are ready for garbage collection. This new fstrim will run once every 24 hours when the battery is at 80% or when the battery is on 30% but on the charger. 

Before this Android 4.3 update the Nexus 7 will pile up roadmaps of tracked data. So this means that if you have a Nexus 7 device that has been progressively degrading in performance then you should get yourself the latest version of Android to breathe life into your device again.

What do you think of this piece of news and do you think that Google should've introduced this update earlier? Please leave us a comment below.

    I honestly did not notice any degradation in speed, but after the update and a few days of usage it seems much faster. So I guess Trim is working ;-)
