Q - EVO 4G Q&A, Help & Troubleshooting

Im trying to partition my sd card so I can have it for roms that utilize apps2sd so I go onto rom manager to pick my ext size and I pic 512 (the largest they have ) then it asks me for the swap size??? No idea what that is it defaults at 32mb with a few more choices ...I have the stock 8gig (7.40) actual space. So...what swap size should I use?

Default options are usually fine. Go with 512MB for apps and 32MB for swap.

[q] vm heap size?

Ive seen in my Build.prop file or whatever its called, I was looking through it and it says a line about the vm heap size = 32, if I changed that to a larger number wouldit make any performance differences and if so what number is recommended? <3
it's better to use some app like SD-booster or system tuner pro . increase your heap size step by step and check witch one is stabler for you .
i already using 1024 , (( for me )) it's better than 512 and 2048
good luck man
Vm heap I changed it to 60 and its faster but ypu need to free internal memory and boost your sd card using rom manager.

When you say internal memory is that app space memory?

Internal storage

On the box it was written that storage is 4gb but when I turned on the phone my phone it was only 980 mb onlyyyy.whyyyy?? Is it possible that the shop that I bought the phone from has changed the internal storage piece??
Sent from my HTC One V using xda premium
I don't think its possible to change the internal storage piece, but I think that 3gb goes to the system storage.
Would someone else with a One V confirm this?
EDIT: did some searching, according to gsmarena 3gb is in fact for system apps
And here is an xda thread regarding the same issue: http://forum.xda-developers.com/showthread.php?t=1586291
EDIT 2: I just found out the One V has a microSD slot unlike the One X and S, so the only thing you need the 980 mb for is apps and data. But since it has microSD expansion, link2sd will work if you really want more space

you have to make partition first...which is supported by kernel....

The procedure is slightly more complicated to setup, since yes you need to partition the SD card (the 2nd partition is how much space you want for more apps), and you have to choose a certain partition format, e.g. FAT32 is supported on all ROMs.
I won't get into the details, there are multiple guides on how to setup and use link2sd.
I will, however, tell you that when using link2sd, nearly every part of the app you are moving, every bit of data, lib files, etc. are moved to the SD partition, and less than a megabyte is saved onto the phones internal storage for each app.

[Q] Help with Link2sd please.

So i created the second partition on my SD card using minitool partition on my PC, but when i try to set the link location in the app it says either device is busy or sdext2 doesn't exist.
Any ideas how to fix this?

Not sure if its relivant but what sd card do you have? Brand, size and class?
I got a SanDisk 32gb class 4 with ex2 and fat32 and mine works fine....
Did you read any instructions on this as well?
Its a sandisk 16gb class 4. Minitool said the original and new partition are fat32, but my only other option was ntfs. Should I recreate it using ntfs instead?

No, NTFS is not supported. What do you mean it was your only other option? Were the ext file systems not showing up as possibilities? Also, how sure are you of the microSD card's legitimacy?
When i was choosing my file system in minitool I could only choose ntfs or fat32. But when i browse using root explorer its in my data folder as data/sdext2. But link2sd doesn't recognize it to link to.
And legitimacy is 100% because I bought it at radio shack

Well its working now. Not sure what happened. Maybe it auto mounted the ext2 the first time, and so when i tried to mount it using link2sd it was giving me an error? Either way, this app is awesome lol.
Thanks for trying to help me out. I appreciate it.

Strange, if I am understanding you right; the 2nd partition was mounted as sdext2 yet link2sd never recognized it...weird

No problem, glad to hear it worked out. It was probably something simple like maybe link2sd not initially asking you for info on the 2nd partition. Regardless, ya, link2sd is amazing. Early on I was always confused between App2SD and Link2SD; the I figured it all out. It's almost pointless to use anything BUT Link2SD. It makes life so much easier, especially with our severely limited internal space on the Xperia Play.

No kidding. This app should be stock on our phones and all roms for our phones lol.

I got 1 more question regarding this app. I have a 16 gig memory card but I'm buying a 32 gig memory card and obviously want to transfer all my data over. Where do I find and how do I transfer all the linked data? I can't seem to access it when I'm viewing my memory card.

Setting swap space

Hi everyone.
My main question is should set swap space to 0 or other number. If I'm not mistaking new Android phones come with swap space not set to 0. I always heard when I use Linux as my main OS that u should set swap space the same or twice of ur ram memory value. I'm asking this coz everyone says to set swap space 0 but ics uses swap space by default and in Linux OS u should never set swap as 0 unless u have enough memory ram(6 or 8gb of ram) and still is not recommend. Anyone who has a better idea of how this works, please explain. I'm very confuse here.. ;(

Then what is the point in set a swap space if the value is 0. The OS is not gonna use it, right???

If the kernel you are using supports swap, then set it

That is the total storage our phone has. Roughly 1GB for apps, 0.7GB for system and around 1.7 GB internal SD card if my memory is serving me right.
