[Sony Xperia P, U, Sola, Go] :
You have noticed right that Xperia U, Sola, Go is slow at times, and you might wonder why it's like this. It has come to conclusion that this issue is related to our phones internal memory (NAND) and the issue is that it's slow and unreliable.

The Sony Xperia U, Go and Sola uses the same NAND memory, the sdin5c2 and is made by Sandisk, here is a datasheet of the NAND:

http://omapworld.com/iNAND_e_MMC_4_41_IF_data_sheet_v1_0[1].pdf

I have done some benchmarking of the NAND memory now, and my theory of it being slow seems correct, especially when it comes to the random write and read speed, which needs to be good for the device to operate in a good way,

Here is some of my benchmark results:

Xperia U

Nexus 7 (Comparisment to see what's normal):

Seem's like Sony have been chosing a cheap and unreliable NAND memory, as these benchmark results really shows how bad it is. Also the slowdown of the phone while downloading apps and such shows it also.

Heres my task for all Xperia U, Sola and Go users, go to the Play Store and download the app called AndroBench and do a full benchmark, then post a screenshot of the result here so I can get a wider amount of tests so that we can see if it's just my NAND or everyones. Also post which device you use and what rom you use, as that might be useful.
[Sony Xperia P, U, Sola, Go] XqepX:
This is the result of my XSola ;)
[Sony Xperia P, U, Sola, Go] :
Pretty much what I did get, so that means my theory might be right.
[Sony Xperia P, U, Sola, Go] Deichz:
Here's mine

Xperia Sola AOSP 4.1.2 ROM

looks like you're right.
[Sony Xperia P, U, Sola, Go] :
Yeah, look's like it, those values aren't normal compared to other devices.
[Sony Xperia P, U, Sola, Go] XqepX:
But I have also a Acer Iconia B1 A71 Tablet and it has nearly the same result ;) But it's 100-120€ Tablet so I think it's acceptable :) Will ask my brother if he can do it also on his Xperia Z ;)

So my bro got following result on his XZ:
[Sony Xperia P, U, Sola, Go] :
Ok, thanks.
[Sony Xperia P, U, Sola, Go] XperianPro:
You should figure out why fps is not stable and scrolling is laggy.

Thats main problem.
[Sony Xperia P, U, Sola, Go] :
Actually that can be caused by slow NAND, as it takes more time to load animations and text and such.
[Sony Xperia P, U, Sola, Go] myawan:
Results are more or less the same at my end as well, I am using Xperia U on Stock ICS.
[Sony Xperia P, U, Sola, Go] Hefko:
Xperia P

Xperia P (row, sio)
[Sony Xperia P, U, Sola, Go] XperianPro:
Well... no,thats not reason,Xperia P also lags and it has not slow disk.

Pretty much same as other models (had xperia p next to xperia u so i know)
[Sony Xperia P, U, Sola, Go] :
Yeah, almost all benchmarks on XU, Sola and Go gets the same because of the nand.
[Sony Xperia P, U, Sola, Go] Little Zed:
NAND is really slow than Nexus but Nexus have more prices than us bro :D
[Sony Xperia P, U, Sola, Go] XperianPro:
Yeah even aosp is not smooth.
[Sony Xperia P, U, Sola, Go] :
By the looks of the Xperia P screenshots Xperia P have another version of the NAND which performs better.
[Sony Xperia P, U, Sola, Go] yew0815:
my sola result on stock 4.1.2

no difference with other phone

My NAND is also slow
[Sony Xperia P, U, Sola, Go] Loller79:
My xperia p lags very bad in all roms, and i've not the same scores as hefko..
[Sony Xperia P, U, Sola, Go] Karchikumar:
Try FXP rom... it all be fine on all aspects....
[Sony Xperia P, U, Sola, Go] Loller79:
It lags too. I tried all roms for my xperia P, they all lag bad.

Especially cyanogenmod 10.1 that is the king of lag.

---------- Post added at 08:19 PM ---------- Previous post was at 08:09 PM ----------

I also tried the benchmark on pure stock rom without any custom kernel, bad scores as before and more laggy as before..
[Sony Xperia P, U, Sola, Go] :
Thanks for all rhe submitted benchmarks :)
[Sony Xperia P, U, Sola, Go] XperiaPD:
If you have bad write performance on xperia p this could be fixed with TRIM but I have no idea how to do this without android 4.3
[Sony Xperia P, U, Sola, Go] Mntz:
I know quite a few people with a Xperia U, including my girlfriend. Literately all of them complain about the U having become very slow and unresponsive. I don't have this issue with my Xperia P. It really must be the slow memory. Good find but I guess there is not much we can do about it.
[Sony Xperia P, U, Sola, Go] waqar bukhari:
it is showing the same result for xperia p jb 1.100, alot of apps installed. browser and fb running. But my phone is not laggy at all. It plays almost every video with mxplayer. modern combat 4 runs like butter. never laggy. In call log scroll do lag but it is JB not my phone who is laggy. I have no complaints. On antut i get benchmark like sola do. But in performance totally different. I don't believe these benchmark apps.
[Sony Xperia P, U, Sola, Go] yew0815:
because p has 1GB ram but sola only has 512mb ram but antutu did not consider the ram size but only ram speed

that is why benchmark are the same but the performance is different
[Sony Xperia P, U, Sola, Go] ale467:
See these results!

It is my Xperia U with stock ICS booted from SDCARD (multiboot feature)
[Sony Xperia P, U, Sola, Go] Wind07:
This is inaccurate as this is SD Card speed and now we are talking about internal NAND Flash speed

Tapatalk sig: I use DraStic to play pokemon.
[Sony Xperia P, U, Sola, Go] dotafan:
U doesn't have an sd.

It's still nand and accurate too

Winter is Coming
[Sony Xperia P, U, Sola, Go] ale467:
U has a unique chipset. Total partition size is 8GB, divided in 4GB of user data (internal storage, NAND), 2GB system and 2GB reserved for apps.

So, test is accurate.
[Sony Xperia P, U, Sola, Go] :
You know right that the sdcard on Xperia U is a partition on the internal nand flash...
[Sony Xperia P, U, Sola, Go] Wind07:
So does u have external sd?

Tapatalk sig: I use DraStic to play pokemon.
[Sony Xperia P, U, Sola, Go] Karchikumar:
Yep U possess a partition of internal memory as storage..
[Sony Xperia P, U, Sola, Go] dotafan:
No

Winter is Coming
[Sony Xperia P, U, Sola, Go] Fortun:
That moment when the Xperia X8 outperforms the Xperia Go of the house...

The slow speed at random reading and writing could explain why some simple actions do indeed happen faster in the X8, such as opening the dialer app for the first time after boot. Of course, once the app is already in RAM this is a non-issue.

The random reading speed could potentially be improved by lowering the read_ahead_kb values for the internal partitions. For this, we would need to know wich directories from /sys/devices/virtual/bdi/ actually point to them.
[Sony Xperia P, U, Sola, Go] lobbos:
I just run the benchmark and here are my results. I'm currently running the PAC Man rom on my Sola and compared to various previous roms, this one runs surprisingly smooth and lag-free.
[Sony Xperia P, U, Sola, Go] Fortun:
Actually, after further review, the results showing what would be normal in the Nexus 7 are nothing but normal. To be more precise, the values for sequential and random writing are off the charts.

Let's take a look here: http://www.anandtech.com/show/7231/the-nexus-7-2013-review/4 .

The best speed for sequential writting comes from the Nexus 10 at 21.94 MB/s. And the best speed for random writing is at 1.65 MB/s. Compare these results to the ones posted originally: 237.75 MB/s for sequential writing and 383.02 MB/s for random writing.

Before moving on, it would seem that the AndroBench app is prone to mistakes. Not only it showed some crazy values for the Nexus 7, but we also have some atypical results for the Xperia P. Thus it needs to be run at least a couple of times, preferably during different times during the day.

Now let's take a look at the values of some phones (instead of tablets): http://www.anandtech.com/show/7251/lg-g2-and-msm8974-snapdragon-800-a-quick-look/6 .

Let's focus on the values that are supposedly holding these phones back: random reading and writing. Taking into account the values that are within normal range, a value of 7.8 MB/s for random reading and 0.22 MB/s for random writing would seem fair for comparison purposes. The values are not that far away from the ones of the Galaxy Nexus. And this values are confirmed again here: http://xdaforums.com/showthread.php?t=1971852 .

I use N7 2012, that's for Nexus 7 2013 dude.
[Sony Xperia P, U, Sola, Go] Fortun:
I don't know what point you're trying to make by bringing that up. If anything the results of the Nexus 7 2013 should be closer to your posted values. The gap is still huge.

Anyway, here are the results for the 2012 model of the Nexus 7: http://www.anandtech.com/show/6130/the-16gb-nexus-7-storage-performance .

The values are even closer to the ones of our phones, specially the ones from the 8GB model. Speed of random writing is only about 50% faster at 0.32 MB/s. And random reading is actually worse at 4.77 MB/s.

hi i want to know how to take photos with the s4 i9500 with blurred backgrounds

so that it focused on the closer object, can't seem to find the option in my s4.

thanks
[Galaxy S 4 Q&A, Help & Troubleshooting] gsmyth:
I dont think this option exists in the S4. I have the i9505 but it should be the same. The only option that would be close would be the vignette filter, but its not really the same. You could just use an editing/camer app to add the effect, Camera360 has a tiltshift feature which creates a similar effect.
[Galaxy S 4 Q&A, Help & Troubleshooting] sadeshmagic:
Well apparently. ...the S4 camera is smart enough to judge a macro image...and its suppose to focus automatically. ..buuuut we all know that's a flop....I recommend Camera FV5....its paid...but you will definitely like it....it can directly focus macro and blur the background. ...just follow the on screen tutorial...hope this helps :)
[Galaxy S 4 Q&A, Help & Troubleshooting] RossFixxed:
I just took this to see, and all I did was tap on the muffin and let the auto focus do the work. If it was angled at the ground it wouldn't blur, there needs to be distance significant enough to cause the natural blurring.

Not much help but it's not an add on or anything just how you line it up.

These roms take a long time to flash, a very long time for some. Let it flash in recovery. Do what others are doing if you need to even if it seems excessive, take a shower or something leave your phone for a while just let it work its course.
[G2 Q&A, Help & Troubleshooting] cor_mann:
UPDATE: I gave up and restored a backup. I'm wondering if the issue is because I didn't wipe System

Hello everyone,

I'm also stuck at the LG logo. I wiped data, cache, and dalvick in recovery. I installed the ROM. Neither of these steps took a very long time. When I went to reboot, it stated that I was rooted and asked whether I wanted to install SuperSU. Since the ROM description stated that SuperSU was included in the ROM, I said no. After rebooting, I have been stuck at the LG logo for over 15 minutes.

Is it supposed to take a long time during the actual install, or at the LG logo? Should I wait it out or work on my backup plan?

Thanks for the help. I'm very excited about CleanROM.
[Android Q&A, Help & Troubleshooting] Sodori:
Hi,

I have been looking about for a tablet for a while now, and I have some questions! First and easiest, it seems that a custom ROM have to support individual devices. Is that because of it's specific screen and hardware or even more to it?

Second of all, I do like my devices to be multi functional. And that's why I like Android, because I can pretty much shape them to the functions I desire. And on a tablet, I would like a stylus actually, to take note and perhaps even do some drawing. Because again, I like multi functional. So you want a more graphics tablet, I hear the back row say, but a iPad! They continue. But I do not want to sell my soul to Lucifer I reply to them. And I start wonder. Because would it at least in theory be that hard to have a stylus mode? All styluses follow a more or less unique to them pattern on the screen so would it not be possible then to setup the Android device to see that "this" pattern appearing on the screen is less than your stylus biggest print but more than its smallest? And thus even recognize a hand plopping all over the screen? With them styluses that have a disk, this would be even more precise! I think not only for me but students, to buy a tablet for under and a stylus that for for 10 times less and use that to take notes. My brother goes in a sort of high school and there students already gotten their tablets actually for this wherry purpose! I bet theirs are them iPads that the school probably can't afford so they will make do some other way, and that's quite a shame in my honest opinion if this is doable.

[HTC One S] redspeed:
Ive been using Odyssey and Beanstalk 4.3 roms along with the latest Bubba kernel. I had been using the phone for several days without any issue then today pulled the phone out of my pocket to see it was stuck on the Beanstalk boot animation.

I tried going to recovery and wiping the cache and dalvik along with fixing permissions but that didnt work.

I then went into recovery and did a full wipe and flashed the kernel cleaner and tried to flash the rom without bubba kernel this time but it still wouldnt get past the boot animation.

Now when I go into recovery it has an error about not being able to open E/Cache/Recovery and reboots to the HTC logo after a few seconds.

What happened to the phone is there a way to fix this?

Can you tell me if by going back to stock, your wifi and 4g both working?

Also, what was your CID ? mine is HTC__001 - Do I need to modify my CID and go back to Tmo in order to run this RUU ?
