If other Samsung phones have been too costly, the Samsung J3 is an option that’s budget-friendly. It manages to stay under $200, and really doesn’t look half-bad with an option for a stylish metallic-gold finish. However, it doesn’t exactly come in at the top of the list in terms of performance. It’s not bad; just not the best.
It also comes with a Lollipop rather than a fresh Marshmallow. To boot, the phone is saddled with some of Samsung’s usual bloatware.
Rooting your Samsung J3 will afford you more control over your phone’s speed and will allow you to really push your phone harder. You can also optimize your phone’s memory, resulting in better performance. Apps that eliminate redundancy and improve automation also tend to work better on rooted phones.
Some examples of apps that will help you accomplish these things once your J3 is rooted are:
Before We Begin:

- Go to Settings.
- Press About Phone.
