WHAT IS ZEBRA'S BUILD.PROP TWEAKS?

Zebra's Tweaks are certain tweaks you can use on your nexus 7 (both Wi-Fi and LTE model) to get the most of it.

DO I NEED TO REPLACE MY BUILD.PROP FILE? WHAT IF I AM IN A CUSTOM ROM?

Well, i prepared a list of tweaks with categories so you can add what you feel you need or want.. also as there are just tweaks or improvements of older lines (like Wi-Fi one) you only need to add, not to replace or remove, so it's very hard to get a bootloop by doing this.

i analyzed (lol please sorry the bad english, dont really know if that word exists.) every single line so i know what i am throwing you, trust me, i will also explain every tweak so you can decide better, you can get lines here you wouldn't find in other places simply because they are not much known, so it's probably that you never heared of some of this lines, but doesn't matter, that's why i am here :angel:

REQUIREMENTS:

a) File explorer (with root support, like ES File explorer or Astro).

b) Build.prop file w/o Tweaks in the ROM.

c) Root (of course)

d) BACKUP of your current ROM (if the thing goes wrong).

WHAT DOES THIS TWEAK CONTAIN?

A) Battery Tweaks:

- Modified Wi-Fi Scan interval value (Scan every 3 minutes).

- Power Saver mode while sleep.

- Smart Connect & Reconnect to save battery.

B) CPU & GPU Tweaks:

- GPU Tile rendering improved.

- CPU & GPU now work better with the Ui.

- More..

C) Visual & Media Tweaks:

- JPEG Quality raised to 100%.

- Better photo quality.

- Audio Tweaks.

- More..

D) Smoothness & Responsiveness Tweaks:

- Removed useless services for Smoother Ui.

- Improved Scroll speed.

- Improved touch responsiveness.

- Scaled touch pressure.

- Nitro lag nullifier (by zeppelinrox)

- More..
