[OnePlus 5 Questions & Answers] TwinAdk:
Hi all!

Just an idea, would it be feasible to use say 2GB of RAM for a drive used to store pictures on, for even better performance? Or is the UFS 2.1 just as fast?

This is an idea for a custom ROM feature, hence the chosen forum section!

Kind Regards

LPDDR4 is much faster, But as we know RAM is a volatile memory and what ever you do goes puff!!!

Unless we create a dump of the ram when rebooting/shutdown-ing
[OnePlus 5 Questions & Answers] TwinAdk:
Good point! Possibly create a control panel to control the usage of the ram drive, and have the content moved from RD to defined destination when the app that saves the data (camera app, download manager, Chrome, Firefox, etc) is no longer in focus?

And then symlink between locations so the system is left clueless :good::victory:

Great ideas here!! :cool:

Linux probably supports RAM drives out of the box, so I doubt it would be that much work.

What the heck are you doing with pictures on a phone that you require better performance than UFS 2.1?
[OnePlus 5 Questions & Answers] TwinAdk:
Yeah, though that's general cache thoughts, this is the creation of a drive, usable by any app, or the user :) Great minds think alike!

I'm just thinking of the write speed that will increase. Then the content can be loaded off the drive when the user is leaving it idle. It will give an even better experience when writing stuff to disk. Do you see the potential that the users write command is done instantly, so the user can move on with things. The system can then handle the offload in the background when the user do not have to wait :svetius::svetius:

I would love that feature!

[OnePlus 5 Questions & Answers] caki25:
Not sure if swap is still in use, but on my old Xperia (and a couple of others) swap was created as a RD and supposedly it helped a lot. With a beast like OP5 though not sure if that would help and if this is still in place and used .. I stopped following a couple threads when I broke that Xperia so kind of digging from memory :)
[OnePlus 5 Questions & Answers] TwinAdk:
On older phones I guess RD makes more sense, but as long as RAM is faster than disk (and you have RAM to spare) RD makes some sense :p:silly:
[OnePlus 5 Questions & Answers] davfiala:
Swap created as ramdisk? That doesn't make any sense. Mounting a ramdisk as swap is worse than useless.
[OnePlus 5 Questions & Answers] caki25:
it does, if you use compression to sort of extend the size of the memory. If configured properly, it might bypass android's swappiness, but still keep the app's data in RAM for faster switchover. Not the most elegant solution, but it just might work. With so much memory that the OP5 has, that it can't really exhaust it, it's a bit pointless.

yeah, agreed, was just thinking aloud. I don't see that much into the internals of Android, but as you said earlier, some sort of quick cache might be worth a shot.
[OnePlus 5 Questions & Answers] yubimusubi:
Running a ramdisk as a mount for /tmp is a common trick on Linux to make processes that write a lot of tempfiles run a bit faster. I don't know how Android handles tempfiles, but if it stores them all in one place like on GNU-style systems in should work as well. But I suspect not many Android apps write tempfiles anyway...
[OnePlus 5 Questions & Answers] ABotelho23:
Of course the write speed will increase. But for pictures, would it not be negligible?
[OnePlus 5 Questions & Answers] TwinAdk:
Yes, it would be :laugh:
[OnePlus 5 Questions & Answers] onicrom:
using tmpfs would be much easier than a ramdisk.

off the top of my head you would need to work out a few things

if you wanted it to be 'persistent' you would need to run some kind of scheduled rsync or background process to sync the data (lsync) to a dir on the ufs filesystem

either way you open yourself to data loss if during the scheduled window, or during the lsync, the phone reboots or crashes

you would also need to write an init script to create the tmpfs mount and sync back the data from the ufs filesystem

What would be a good candidate for 'ultra fast data'? Maybe the dir the camera stores files? What about the cached data each app stores?... you would probably have to limit this to a certain set of apps because you could run into an issue with space depending on how large you make the tmpfs mount...is that even something possible? I can't remember I haven't look at where the cache is stored
[OnePlus 5 Questions & Answers] yubimusubi:
A memcached style setup might be nice... But that's probably similar to how the "app priority" feature works.

I'm actually looking for a way to create a ramdisk on my OnePlus 3T.

Is there any detailed description/explanation of how to make one or if there are any apps available that can do it for me?

[OnePlus 5 Questions & Answers] Desmanto:
Sorry to bump up old thread, but maybe other are googling and directed here. So I better post my finding here and maybe other can benefit.

I have been searching for the holy grail for so long and finally found it. I am using RN5 whyred and trying to reserve 100 MB RAM for temporary storage and file processing for my Automagic flow. It is meant to reduce write cycle on the emmc. I have been trying to mount tmpfs on the /storage/emulate/0 and found out not working, the file still stored on emmc. Because I tried to reboot and the file still there.

I am currently using custom ROM AEX 6.7 Pie 9.0. When I use command mount, I can find tmpfs is mounted on /storage/self. So I thought to create a new folder inside it and chmod 777, /storage/self/ramdrive. Then I copy file to it using MiXplorer. And the speed is amazing.

I then check on the command free | grep Shmem

The size is increasing, means the RAM is being used for the storage. Deleting the file will reduce it, so it is working !

Testing copying file to internal storage, 750 MB takes about 12 seconds, while copy to the ramdrive takes about 5 seconds. Leave the file at ramdrive and restart the phone, the file disappear. So it is confirmed that the file is stored at RAM.

So for other, if you want to mount ramdrive, you need root. You need at least terminal emulator. But MiXplorer with root access can also create the folder. Try to check your tmpfs file first using

mount | grep tmpfs

I found several and use /storage/self. So I create additional folder there

mkdir /storage/self/ramdrive
chmod 777 /storage/self/ramdrive

This folder disappear at every reboot, so I use Automagic startup to recreate it at every reboot.

I then point my flow to save or process file at that path. By default the limit is half from the total RAM, which is 2 GB from my 4 GB RAM. I am thinking to find the script to limit the size, but rather than playing with the mount script, I better disciplined my flow to not store too much here.

Using the ramdrive, now I can lavishly store and delete temporary file there without worrying reducing my emmc lifespan.
[OnePlus 5 Questions & Answers] piduca2011:
I know, topic is old... But I found this discussion while searching for a solution to my problem, which is as follows:

I want to run a Dos emulator on my android device (to play windows 3.11 and dos games). I will do it with Magic Dosbox or even Limbo PC Emulator.

Point is: given the poor lifespan of sd cards and internal storage of mobile devices, it would be great if I could run such DOS "virtual machines" on ram disks, to avoid degrading the mobile's storage with all the read/write methods on the disk image (in case of Limbo) or in the folder (in case of Magic Dosbox).

So, I ask:

a) do Magic Dosbox have this feature? (I didn't find it on the documentation)

b) can I prepare a ram disk before running Magic Dosbox, to load a specific folder content or a specific disk image?

So I'm not too thrilled about the 6 GB/64 GB version we're apparently getting in Canada, and am seriously considering getting an 8 GB/128 GB version on eBay, but I'm concerned about it being a Taiwanese SKU/serial.

Does anyone have any experience or thoughts as to whether it would work in Canada, if updates would come properly, etc - or better still if I could just flash it to the NA version on arrival, etc.? Thanks!

At the moment I am only able to find this phone available for purchase in Sweden with 6GB of RAM and 128GB of internal storage.

[Asus ZenFone AR Questions & Answers] zman2107:
The Amazon or global one is GSM network Verizon and Sprint use CDMA networks . So the info on their site is correct.
[Asus ZenFone AR Questions & Answers] Slack3r:
From my testing, the unlocked version will pick up Verizon LTE bands but calls fail since there is no VoLTE option on the phone. Did not pick up any of their 3G signals, and their system would not accept my IMEI as a compatible device. So it may work if you can convince Verizon to add the phone to their system, which is unlikely since they already have their own version.

FWIW I also tried it with a Sprint SIM, but got no service whatsoever and their system would not accept the IMEI. Thew in a Cricket/AT&T SIM and the phone worked as expected.

Which LTE Bands are you getting?

I'm on T-Mobile,seems we only have Band 2 support on the WW unlocked 8GB/128 GB Model. :rolleyes:

I've already initiated a return w/the e-Bay seller,more than likely,it's going back tomorrow.

I'd been OK with Bands 2 & 4,which are listed here:

https://xdaforums.com/showpost.php?p=73425969&postcount=2

The fact that they let this .pdf out & it's not even accurate speaks volumes for North American support:Tone-Deaf would be a compliment...............
[Asus ZenFone AR Questions & Answers] Slack3r:
I was able to get service on 4 and 13 for Verizon, and 2 and 12 for Cricket/AT&T. It may support more, but I'm not aware of any apps that will let me scan for service on all bands. LTE Discovery mentioned a "Potential eCSFB issue" with the Verizon SIM which is likely because there was no CDMA support.

Fun fact... apparently the phone supports XLTE with Verizon, which led to a rather depressing speed test compared to my service with Cricket.
[Asus ZenFone AR Questions & Answers] KOLIOSIS:
Are your results with the VZW model,or,the unlocked model?
[Asus ZenFone AR Questions & Answers] Slack3r:
These are from the Unlocked 8GB/128GB model from Amazon running the WW firmware.
[Asus ZenFone AR Questions & Answers] KOLIOSIS:
THX!,just wanted to make sure we were talking about the same model phone.

I'm gonna give it one more day,get around town & see if the connectivity is OK.

If spotty (w/Band 2 only) ,I'm sending it back,or,selling it on Swappa.

Outside of sparse LTE Band support,it's a nice phone,I really don't wanna part w/it so soon after getting it.

Haven't tried out the AR/VR Capabilities yet,but,I do like the display & the speaker quality/loudness.

TBH,I'm covered in WI-FI Most of the time,but,I did expect better LTE Band support nevertheless,especially for a DualSIM/Unlocked phone.

The fact that it's being sold on Amazon as-is seems to be Asus shooting themselves in the foot,certainly there'll be quite a few returns,once people find out connectivity is less than ideal for an unlocked phone,one that is marketed to the US/North America.
[Asus ZenFone AR Questions & Answers] HipKat:
Update on mine, battery life is getting better now as the phone settles in. NOT impressed with Data though. I was in the country yesterday, my ASUS Zenpad had 2 bars of 4G and the Zenfone was in roam. Everything else is great, and living without root is bearable, I guess. Fortunately, my 7 year high score on Klondike is an X-Box Live/Google Play game and the score were carried over from the X Box cloud. I know that sounds silly but 7 years over multiple devices is a long time to build up a high score and was a major stress point going to a locked down device
[Asus ZenFone AR Questions & Answers] KOLIOSIS:
Seems the LTE Support is there after all (for North America):

Since the VZW model has its own model number (V570KL) ,I took it for granted that the other model number (ZS571KL) was a true one-size-fits-all for all other markets.

So far,it seems there will be a minimum of three different firmwares under the same model number:

WW:World Wide

NA: North America

JP: Japan

Well,I'm relieved that I can get a better-matched version for T-Mobile US via Amazon,I'll be returning my eBay purchase later today & paying a restocking fee.

My impatience bit me in the arse by not waiting for Amazon to have stock,but,I partially blame ASUS for having at least three different firmwares sharing the same model number,yet,giving the Verizon model its own model number.

No rhyme or reason there,considering other mfgs make the clear distinction in the model number for different regions/carriers. (Kudos to OnePlus,luv 'em or hate 'em,for having one global SKU for all on the OP5).

Again ,the mistake is ultimately mine,I hope others read this & don't make the same mistake I did.
[Asus ZenFone AR Questions & Answers] Slack3r:
I'm actually not sure there's an NA specific firmware for the unlocked model, mine came with the WW firmware and they only have WW and JP listed on the support page. I am picking up LTE bands that they only have support listed for on the "NA" model so I think it may just be a case of poor documentation.

I'd be really interested in whether or not we could flash the Verizon firmware on the unlocked version, but so far I haven't been able to find an image.
[Asus ZenFone AR Questions & Answers] KOLIOSIS:
I'm only getting Band 2,which is just what the specs list on ASUS' website.

They show a different set of LTE Bands for North America that I'm not picking up,so,there's a difference somewhere.

I got mine from a Taiwan-Based seller & upon further review,their description for LTE Band support matched what is on ASUS' site for the WW Bands. (No Band 4 or 12 for WW,only for North America).

I'd just wait for development/flashing tools/etc... if this were a more mainstream/popular phone with wide support,but,I decided to bite the bullet & eat the restocking fee on my WW Firmware version while the return window still exists.

It sux,but,it's a relative small price to pay vs. being stuck w/a phone that has only the most minimal LTE Support on T-Mobile US.

I'd probably have a hard time selling it on Swappa as well,most that frequent Swappa are only going to only be interested in the North American Unlocked (NA) or the Verizon version.

Where did you purchase yours?
[Asus ZenFone AR Questions & Answers] Slack3r:
I purchased this one from Amazon:

[Asus ZenFone AR Questions & Answers] KOLIOSIS:
Cool,THX for the info you've provided.

Nice (for me,LOL) that you were able to connect to LTE Bands 2/4/12 on VZW/AT&T,I should have no problem connecting to the same bands on T-Mobile w/the Amazon/North America version.

As you previously stated,some crappy documentation/firmware naming from ASUS,a clearer distinction needs to be made from the various firmware installed.

Samsung makes easy work of it,for the most part,they just add a single letter on the end of the model number to make the distinction.

It's not rocket science ASUS,no need to unnecessarily muddy the waters ............. :rolleyes:

How's the camera working for you guys?

I really didn't get a chance to put mine through the paces before I returned it.

Reason I'm asking is this review from 9 TO 5 Google has me a little hesitant to order it again:

https://9to5google.com/2017/08/22/asus-zenfone-ar-review/

(Fast-Forward to the 2:05 mark for camera issue)

[YOUTUBE]8ZzzUNjGD_Y[/YOUTUBE]

The reviewer mentions the camera freezing up & force-closing,sometimes working,other times,freezing up for hours.

Considering the camera is one of the main features of the phone, & although I'm a relatively light camera user,I do need for it to work as intended,most pics I take are work-related (zooming-in on serial numbers/data plates/etc...).

Anyone here experience this at all?
[Asus ZenFone AR Questions & Answers] dantegl36:
I've had this phone since June and the camera has never frozen once and I've had zero other issues with it.
[Asus ZenFone AR Questions & Answers] KOLIOSIS:

Could be any number of things this one particular reviewer has going on (optimization of the camera app/etc...).

Currently, I'm awaiting for the refund on my WW model (purchased from eBay) to apply to the purchase of the 8GB/128GB model from Amazon.
[Asus ZenFone AR Questions & Answers] HipKat:
Same here. Not one issue. This re view is based more on opinion than anything else. I get it. The reviewer doesn't like ZenUI. I use nova Launcher Pro so I don't even need it. The camera has been amazing so far.
[Asus ZenFone AR Questions & Answers] KOLIOSIS:
Yeah,there's very few reviewers that have the ability to be unbiased & just review the device on hand for what it is,w/o injecting too much personal bias.

I know the sample size is small,but,just having a couple people speak up here & given how long y'all have used the phone vs the reviewer in question has a lot more credibility & honest/unbiased input.

The refund from my eBay AR hit my PayPal account early this morning.I had full intention of ordering the "right" one from Amazon,but,I decided to pick up the Note FE again.

Both are nice in their own unique way,but,I opted for the Note FE before supply dries up/becomes any more expensive.

Odds are I pick up an AR again,probably by year's end,there's not too much else out there that has anything unique/interesting going for it.

Ya spend this much on a phone,might as well get one that has a feature or two the rest of the pack lacks..............................
