Is there any way to speed up an out of date phone? I have two one being the s3 and the other being the s4. I bought them off of a friend for $30 each. Both work fine but they are VERY slow even after wiping the software clean. I am not sure how to fix this. The s3 will also freeze up a lot when browsing online or using video related apps.
Yes. You want to use apps that will help it out. I recommend downloading SD Maid and File Commander for starters. Read up on other options. You want things that well help manage the files and memory on the phone while cleaning it up. It wont be fast as it was when it first came out but it should be a 50% improvement.
Andddy I can vouch for File Commander... so helpful when I was working with the SD card... magnificent.
I found that periodic factory resets help speed up the phone.
Older Galaxy devices seem to have tons of bloatware, you try disabling all the non-essential system apps. Installing a custom ROM like CyanogenMod could also upgrade and speed up the Galaxy S4 and S3.
If you do the resets, though, be careful as to backup your data first... Don't want to brick anything.
I was thinking of just wiping the phone and rooting it. I am not sure how hard that is. I gave the apps a go and I did not see much of an improvement. It was back to normal the next day.
Why do you want to root it though?
