[Samsung Galaxy SL i9003] spacebar2011:
Okay, there's a lot of info strewn all over the place on several threads and I can understand how a newcomer might get perplexed by the overload. That said, please use the search function, spend some time reading through pages, see what others have already asked/answered/solved and then, if you still can't find what you're looking for, PM one of the senior members. Posting old questions or obviously noob questions on the thread makes it messy. Please help keep this forum clean and effective, its for all of us.

Now, assuming that you've got through all the usual stuff (flashing, rooting, deodexing, CWM, electron beam and overscroll glow and now ext4 conversion), I'm posting a few things that might help make your device just that bit snappier and joyous to use:

1 - V6 Supercharger memory script

Edit: If you're using Juwe's Ramscript, I'm not sure if there will be conflicts. Try it though, can't be fatal!

> Download Script Manager from Market.

> Download attached V6_Supercharger script and place it in /mnt/sdcard

> Open Script Manager, allow SU and now browse to the script. (Busybox 1.18.2 recommended.)

> Press the script and on the next window, select "Run as root" option only. By default, the "Is script" option is selected. That is the correct option. Leave everything else as is and click "Run".

> On the script execution window that follows, look carefully. At the first prompt, which is for auto-scroll speed, touch the screen to bring up keyboard (avoid touching the menu or back soft-keys). Type "0" on the keyboard and press "Enter".

> At the next prompt, select option "11" (type it on the keyboard and Enter). Now look at the values it produced. If it says "Laucher is Hard to Kill".. well done! :)

If not, select option 12 the next time.

> Now, select option "8" and Enter. It sets the Minfree values. Its sort of an automatic Task killer but much more effective and does not harm the filesystem.

You could also use option 9, depends on how your device responds after you've used 8.

> After running, select option 17 to finally close and exit.

To understand what Minfree values are, search around or PM me.

Note

: Minfree values have to be set every time you reboot. They don't hold after a reboot. The HardToKill holds, but Minfree values do not. Also, after the first time you run HTK, you need to reboot for it to take effect. Minfree values are instant and do not need reboot. You can also place the widget on your screen to run the script directly after reboot and just set the Minfree values.

2 - Recalibrate your battery

by letting it drain completely (let the phone die) and then plugging it in till its 100%. You can switch on the phone after about 5 mins of plugging in. Avoid using Wi-Fi or mobile data during this time. I think someone did point this out earlier, can't remember who or where.

Edit: It was Misledz as it turns out. ;)

3 - Use Touchpal keyboard :)

Get the attached apk and install it. Its a Beta (its share Beta, so should not be against forum rules) and still not on Market, but it works great and imo, kills Swype or any other keyboard I've ever used. The lags and hiccups reported by other users should be eliminated. Just disable those stupid pluck sounds and keep the haptic at a low level.

4 - GTalk with video

(credits - britoso, Somator, xilard and many others who made this possible)

This is a port from the Nexus S, modified to support as many devices as possible. Get attached apk and install. Don't forget to thank I2asta for the instructions. ;)

To avoid any confusion or screw up, I have repacked the .zip with only the two files needed. This needs to be done manually as the instructions say. Use Root Explorer or File Expert.

Do not download other zips from the original thread or anywhere else or try to flash an update.zip through CWM. If there was a flashable version, I would have put it here!

Original thread is here. I just tried to make it easy and simple to club it along with this post.

5 -

Those who haven't yet tried the new Market, apk is attached. Just install normally. Backup old Market before installing though.

Anything else? Feel free, its a forum! :p
