Casper, you mention horribly slow transfer in cm11, a couple hundred KBps v.s. 7 MBps in stock. I have noticed slow transfers in cm11, one of the things I mentioned about a month ago, between phone and PC. But I am using WiFi in ES Explorer to do this. Stock or longer ago previous cm11 I was getting several MBps and now it seems slower like less than 1 MBps, in the KBps range. Micheal (Stargo), heard me mention it and came back to answer some of the groups questions. He told me that on occasion, as far as he knows, the WiFi module (Best as I recall.) could hang and give slow transfers but it is rare. Toggle WiFi on and off and it should clear up. Well, it didn't, really, for me.

So give us some information to work with. What build cm11 are you on? (Settings/About Phone) Like the build date. 07/17? What stock rom are you using? WiFi transfer or USB cable? App you are using, Windows Explorer on USB, ES File Manager on WiFi, AirDroid, what? If possible can you use the same method and app in both roms and is the problem still there?

I am really late for a new website client and really need the money so I must scoot now. Can test speed for you later to give you a comparison. Pick a nice size file to transfer, A rom is good, that is about 200Mb and time how long it takes or just report the speed. Try to use the same method and app in both roms.

If you can supply this information it would help:

WiFi or USB cable?

What app used for the transfer?

Same app and method used for both roms?

cm11 rom build date?

Stock rom name? (And build date if you have it.)

When I get back later, I will do the same so we can compare results, that might help narrow things down a bit. TTYL

Hi Ohmster

I was using USB. Standard transfer via windows (7x64) through mass storage mode.

CM ROM is 05/17. Stock ROM is rooted (obviously) JB UK retail (not sure on build date).

As you may have mentioned this, then you will know that I've experienced this on other CM builds (maybe even all, but I couldn't tell you for sure).

I installed AirDroid to try it out again, but haven't tested it really.. Not too worried about WiFi now as I can only use it at home - which is what I'll use if it's faster. But at work I must use a cable if I want to transfer files.

I'll try a local transfer on phone from internal to SD just for the sake of it. I'll use Solid Explorer.. If it's slow I'll report back.

Interesting find by blackops11252 on the liquidsmooth thread relative to battery drain. Looks like he linked extended wakelocks back to Google Play Services. I've arrived at a similar conclusion using BBS and tried converting it to a user app with TIBU and then hibernating it with Greenify. I couldn't get that to work however.

blackops11252 interrogated the app's settings using AppOps and it showed the keep awake permission to "on". He toggled it off and is assessing performance. I'm using AppOpsX (native AppOps crashes my settings in CM11) and I think the companion setting is "wakelock" in the AppOpsX version. I'm checking as well - I was seeing a device awake time of about 30 percent of my total up time. I'll report back if it lowers.

Alright Casper, you sound more determined and have a plan of action, all very good. Sometimes we just need someone, anyone, to take an interest, give us a shot of confidence that we are on track. It works for me and I try to give anyone a boost, if I can or help them with issues as well. My transfer rate, XT912 to Windows 7 Ultimate X64 USB is...

...about 2.5Mbps, fluctuating, dropped down to 1 Mbps. I tried it with Safe Strap 2.73 since I need it there anyway but the file was too small to get a speed read on it. So, I sent a rom over to test and that is how I got my speed read.

AirDroid is very good but it is designed as a PC app, even though it installs on the Android. It will give an IP address at startup and you can then connect through a web browser to the IP address and port. Once connected, you use the AirDroid Desktop in the browser to do what you want. Transfer files, music, whatever. It you want to sit at your PC and transfer files through WiFi, this is it.

Another option I like for WiFi (Among other things.) is ES File Explorer. It is a Root File Manager and not only manages files on the device, all mounted cards or drives, it also will transfer to cloud like Gdrive, Dropbox, or whatever, or to LAN via WiFi to access your share drives on the PC. I like this a lot and use it all the time because I can sit anywhere in my home and grab my files, like I just grabbed the new Safe Strap 3.73 that way. Very easy to lie on the couch and put and take from the PC, laptop, or anything on the home WiFi that way. I use this for almost everything unless the file is in the Gigabyte range, then I just use a USB cable to speed it up a bit.

You sound much more confident now, have at it, Casper. Be nice and tap the "Thanks" button for posts that you find helpful. 'night my friend! :highfive:
[Motorola Droid RAZR] Ohmster:
Hmmm, I have not updated any kind of gapps since I installed them months ago as I am pretty sure they are self-updating. So I checked your link against my version in Settings/Apps. Same version on both, Google Play Services 4.4.52 (1174655-034). Thanks for the tip, though. :D

Ooooooooooohhhhh. Well, not everybody is having issues. I don't think that just having Verizon is enough to cause problems with all phones. I must be "missing something". Well, it is a lead to follow up on. While talking to Micheal, he says he has never seen the issue because he is in Nuremberg, Germany and uses T-Mobile GSM. We are in the US and use CDMA, totally different radio in the phones. So this is very difficult for him to fix if he can never see it or reproduce it. He mentioned that AFAHK, all of the affected phones seem to be XT912, Verizon US.

This is not fact or anything, speculation and hearsay I guess. I still want to help though. Maybe I will ask a few what carrier they have with this problem or try to find a common link. I really think Stargo could use a little help, any kind of help that points him in the right direction. Help me think of any common points in the affected phones, like cops do when they link crimes. "All 3 victims used the same Gym, Bart's Health and Gym". I mean, if you can think of anything to pursue, Jake. Can we try that you think?

(I will make a PSA post in a little while. I want to wait for someone else to post so my post does not link together with the previous ones and I can assign a Subject.)
[Motorola Droid RAZR] jeff_roey:
I've been running with the Google Play Services permissions set the way I described since this afternoon - with keep awake toggled off using AppOpsX. As a test, I've added calendar entries and contacts from my desktop that instantly synced to my device, sent/received Gmail without any delay, found lock and history with Maps just as quick as before, and received an app update notification from the store without needing to check.

As far as I can tell toggling "stay awake" to off isn't having any effect on the google services I rely on. Jury is still out on contribution to battery life. I'll be leaving my phone unplugged overnight tonight and I'll check hourly battery burn rate/deep sleep time using BBS and compare it to previous observations and report back.

Running VZW XT912 on 05/17 with stock kernel.

Edit: oh and Google Device Manager still finds the phone!
[Motorola Droid RAZR] Ohmster:
Oh wow, that's really good news. As you can see, I am a little more conservative about my phone. I can tweak and modify like everyone else but try to use the phone and update system, "As an average Joe, housewife, or kid" just to see if the rom is getting stable to the point where it can release. If the rom is strictly for geeks, then only us would and could enjoy it. So I use OTA updates and keep it simple for now. Besides, with NIGHTLY builds, I would spend ½ all my time updating and tweaking if I took that approach. When I get a build I really like and keep for a while, then I "jack it up" and start modding it to my likings.

I was a little bit nervous about the Device Manager and you put my tensions to rest, I appreciate that and your diligent reporting. We live for good reports in here. Now, the question remains, it is significant enough to improve battery life enough to implement? Let us know, dear fellow, let us know.
[Motorola Droid RAZR] d.casper.b:
OK. So on my quest to testing my transfer speed over USB via pc on CM11, I did a clean install of 05/17. Although I cannot be 100% sure I didn't notice much (if any) of an improvement.. but my testing was cut short by more vital issues I need sorted.

Apps on SD are still vanishing (I only have two that default to SD on install - and this xda app I'm currently using to type with is one of them). I think they vanish after a mass storage connection (UMS) to the PC.. but I can access my SD card in solid explorer after disconnecting; which means it has mounted. Moving apps to internal storage does the trick here for me.

But now!! I am once again experiencing "reboots" after disconnecting phone from PC. And this after a fresh install! I disconnect device in Windows, then when I click the "turn off USB storage" on phone (or if I just unplug the cable), the phone "reboots". I get a boot animation, the phone boots up, but does not ask for my SIM pin. Any apps on SD disappear and will only return if I reinstall them or reboot the phone myself.

I have been plagued with this "rebooting" for so long. I recently got rid of the issue unintentionally:

I installed M6 snapshot but had issues with it, so I went back to 04/05 (by flashing, not restoring). The issues caused by M6 remained present, and so being a little lazy, I did a factory reset via the phone itself. Turns out I ended up fixing the "rebooting" issue. But as far as I remember (sometimes you just don't pay much attention when you really ought to have) the apps installed on SD would still vanish, but I cannot be sure as I believe I moved the apps to the phone's memory.

Does this mean another factory reset is in order? I sure don't have time now, so I'll leave it for now - and it's not necessarily been proven to be the event that fixed the issue.

It seems I'm all alone here..

Just remembered now: I made a backup of my CM11 ROM after updating SafeStrap...hmmm.

I did however delete rom-slot1 and recreate it for my clean install (I used slightly adjusted partition sizes to the old rom-slot1). Hope a restore will work.

Edit: Restored my backup, and it looks like the "rebooting" part is sorted again (this after only one test though).

Am I doing something wrong here that my phone reboots after mass storage mode has been disconnected from PC (on a clean flash)?
[Motorola Droid RAZR] eazha:
This rebooting already exist for quite long in different roms...i've experienced this each time disconnected from PC via UMS...
[Motorola Droid RAZR] DumbleCore:
Maybe this belongs to your SD? Had this problems with a class 4, then got my class 10 Samsung 32gb, transferring files with 12mb+ per second

Don't have any reboots since 4.3.1

Really strange

[Motorola Droid RAZR] d.casper.b:
Rebooting is at least experienced by others..a bit relieving.

Lol, i have a class 10 sandisk ultra 16gb.
[Motorola Droid RAZR] eazha:
i don't think becoz of the class issue...same sdcard been using from early kitkat courtesy build without any reboot....then if i mistaken this rebooting happen since march build....but it still not a big deal for me....as long it stable enough for daily use:thumbup:;)
[Motorola Droid RAZR] aldiandrew:
just want to say thx to ohmster too keep reported whats going on for this wonderful nightly rom, post from ohmster maybe a long but its full of fun and helping for noobs like me to know what happen with newest build, :victory:

thx too for stargo keep this development alive, for my side using xt910 with worldwide version never have a problem with *strange* orange bar or network problem from first kitkat CM build hope this fix for verizon version after 4.4.3 release (anyway i read on android news this will launch on nexus at the end of May hope this true after that all kitkat build will fix the network bug which is google produce for that)

anyway for some info if courius about what include on next CM nightly build we can open http://www.cmxlog.com/11/umts_spyder/ to track the change on gerrit. maybe this look confusing but for a while i try too learn and with help of google-ing off course then we will know about the progrees :)

keep omap 4 rock everybody:angel::angel:
[Motorola Droid RAZR] Ohmster:
DumbleCore, you are obviously a Senior Member with a lot of help experience. Can you tell me a little bit more about this "SDCard class thing"? I never heard this term before, I just label them by size. What is this "class thing"? Can you tell me a little bit about it? Thanks buddy! :confused:
[Motorola Droid RAZR] jeff_roey:
Had this at my fingertips. Class essentially equates to the MINIMUM data xfer speed of the card:

There are two kinds of Speed Class, "Speed Class" and "UHS Speed Class."

As a characteristic of flash memory, actual transfer speed varies. Variable speeds are difficult to reliably record streaming content such as video because it requires a constant writing speed. Speed Class and UHS Speed Class provide the constant speed necessary for video recording by designating a minimum writing performance so that minimum and constant speed is guaranteed for camcorders, video recorders and other devices with video recording capabilities under the conditional write operation specified in the standard.

Speed Class, designated as Class 2, 4, 6 and 10, is designed for normal and high speed bus interface (mode) and UHS Speed Classes 1 and 3 are designed for UHS bus interface*. (Speed Class and the UHS Speed Class are not compatible.)

*UHS (Ultra High Speed), the fastest performance category available today, defines bus-interface speeds up to 312 Megabytes. <---- UHS not compatible with a lot of legacy devices.
[Motorola Droid RAZR] d.casper.b:
Yes, and class 10 is perfect for our RAZRs (in my opinion). Even the SanDisk Utility app suggested I buy the SanDisk Ultra (which is a class 10 I believe) - lucky for them, I bought one; and then only learned of the app.

I will keep playing with the reboot issue (but I think I'm free of it thanks to the backup I restored - I mentioned this a few posts earlier). But since you (Ohmster) mentioned the phone taking long to turn off mass storage I realise now that I may actually have been disconnecting the cable before the spinner stopped...because it seemed it never would, which made me believe it was really just waiting for me to unplug the cable.
[Motorola Droid RAZR] DumbleCore:
Just have a look here, everything about classes very detailed explained!

[Motorola Droid RAZR] Ohmster:
Thank you jeff_roey & d.casper.b!

Well, apparenty SDCard speed and class are parameters I need a closer look at. I have a SanDisk Ultra 64GB MicroSDXC Class 10 UHS Memory Card. Good price for a $64Gb SDCard @ $40 on Amazon. Check the link. Says this is a class 10 card. I hope that means "good". I never even considered SDCard performance to be a factor. Since it is all solid state, I am thinking "speed of light" stuff, like my PC SSD. Now THAT is one piece of computer hardware that made a HUGE improvement on my computer. 5 minute boot times now at <30 Seconds. Ten minute restart time down to maybe 40-50 seconds? I assumed the SDCard would be the same.

Alright, well, considering all of this new information, it looks like I have some testing to do. Perhaps A1 SD Bench will give me some accurate results to shed some light on this copy/speed transfer speed issue.

Couple that with USBDeview to insure I have selected an enhanced USB port, capable of at least USB 2.0 or if supported, USB 3.0.

This is an oddball app, it lists my internal card as 64Gb and my external card as 8Gb. These values are obviously reversed, let's test the 64Gb card. I don't get this app, the results show like a billion SDCards. They are all in blue but for XT912 I got results as Read=15.97 MB/s and Write=7.60MB/s. Hmmm. Is this like "good"? I am used to megabits per second rather than megabytes per second. This is really confusing. I want MY results, not everybody in the world's results. See Screenshot. Anybody have a decent SDCard speed test app to recommend? :confused:
[Motorola Droid RAZR] d.casper.b:
Hi Ohmster. I tried an app from the play store (A1 .. something - just searched for "SD speed test") and it indicated that transfer speed is normal from the phone itself.

Clearly not the case when using mass storage on PC.

I have come to decide that if I need to transfer from a PC I'll just go into SafeStrap recovery and mount from there. No hassles there.

Oh, and, I wouldn't pay too much attention to the USB port. I use a USB2 port on my work PC and a USB3 port at home. Same results. Phone isn't using USB3 anyways.

[ On a side note: thanks to you I downloaded ES file explorer... but then I did not use it before I went into trusty ol' Solid Explorer (because it is feature-rich too -it's not free, but oh-so-worth-it; and since I paid I'd like to know I can use it before looking to a free app for assistance).

Managed to connect to my external 2TB HDD that is connected to my router. Why have I overlooked this for so long? Just need to get it to connect to PC, but think I need to set up PC correctly. It keeps asking for a username and password. Will sort that out later tonight. ]

I'm giving a shot at 20/05 nightly and it's going quite well at the moment, no orange bars and no ui reboot so far...

I have a XT910
[Motorola Droid RAZR] Dwillian:
Ditto on XT912.

I've been on the 5/20 nightly for about 24 hours. Lots of changes in 5/20 and a lot more in 5/21. Now I'm updating to 5/21 nightly to see if it is even better.
[Motorola Droid RAZR] morr22066:
The 5-21-14 build running smooth so far

Installed the 5-21-14 build and so far it seems to be running smooth. There have been a lot of updates in the last few nightly builds and it looks like they are working on some performance enhancements...
[Motorola Droid RAZR] adistf:
Updated to 21.05. It's faster,but memory loss is present. used it for 30 mins and from ~430MB ram free i went to ~200.Had to restart to get it work.I hope it will get better soon.
[Motorola Droid RAZR] Dwillian:
Last couple builds seem stable, but realistically it's too soon to give a good number. Based on my experience over the last 30 hours or so I would say 7-8. Earlier May nightlies were much less stable, perhaps 3-4. So, much improvement lately.
[Motorola Droid RAZR] Crumplet:
Thank you for your honest reply.Please update your emotions on the results of this rom future reference, i need a break from testing other roms.

Orange Bars

Man, I love to talk but not tonight. Bone tired. Few hours sleep past couple nights, up at 6:00 take mom to airport. Can hardly stay awake. I want to read what I missed but must get some rest first. I will be back! ;)

Orange Bars:

I was on 05/17, liked it until next day driving around, then signal drops and orange bars. I did update update every day since, OTA, hoping this would clear up. On today's build now, 05/21, still stuck with orange in the house so I wanted to try something different. I went into Safe Strap, wiped cach, dalvik, and android secure. Rebooted. Wow, no orange, but then turned orange within couple minutes. I toggled airplane mode, got the orange gone, and it is staying gone. Not fixed or anything like that, just a work around. I am going to drive a few miles to get Popey's Chicken for dinner, acid test to see if this workaround will hold for a while.

I know after 05/17 I had bars, so I updated each day, (looked at change log), hoping to just lighten up on the orange bars for a while. No, not after 4 more updates. It cannot be this bad in the rom, maybe I have something in my system that is not getting cleaned or wiped. Only thing I could think of that would be safe to wipe is android secure.

Got an update from Micheal about the signal problems, too tired to re-write it, give you all a direct quote.

I still think it is carrier related. Okay, dinner, bed. Still no more orange bars. I hope this workaround will help others who are having to put up with orange bars constantly. I have been OTA updating so maybe my persistent orange bars are because I did not go totally clean, thus the android.secure wipe, then airplane toggle.

If I get orange by the time I get back from this maybe 10 mile trip, I will let you all know. :confused:

Update:

Okay, I drove to the chicken place, 5 miles out, 5 miles back. Keeping my eye on the signal bars the entire time. I got signal drops alright, never to 0 but to 1 bar and they cleared up as I drove around. On stock, the bars are always solid 5 'round these parts. No orange at all! When I got to the gas station by my house, oh no, orange bars again! Toggled airplane again. Still orange. Left the gas station and on the way to car, pretty color icons again, no orange. And that is pretty normal. Once cannot stay on the Google servers 24/7 w/out ever losing contact. Now that I have no orange, I am getting like 20 app updates at once, they would not trickle in like before as each app updated.

I think that I got some "crud" in the phone from a pretty bad build and although OTA does wipe and install a new update, the crud was somehow staying. Wiping android.secure seemed to make a difference. This is the first time in 4 days, 4 updates, where I have regular signal icons. The issue is not fixed, and some orange bars will always happen, but for me, this is like an oasis in the desert. Finally the phone is much closer to "normal". The two screenshots of the signal bars says it all. :fingers-crossed:

Thoughts and verification by someone else would be *very* welcome! :D

My lock screen wallpaper still gets distorted when changing orientation on wakeup. Also on wakeup, my home screen will display prior to the lockscreen.
[Motorola Droid RAZR] jeff_roey:
I'm using Apex launcher and I noticed that when I unlock my device, it briefly displays the bright blue default CM11 wallpaper before going to my chosen homescreen wallpaper (solid black). In order to stop seeing the bright blue default CM11 wallpaper momentarily, I set the Google Launcher as my home, changed the bright blue wallpaper there, and went back to Apex. Solved my problem.

Which launcher are you using and could your issue be similar?
[Motorola Droid RAZR] Ohmster:
My lock screen wallpaper does not rotate. I can enable it in Gravity Box, but do not. See screenshot. Since the lockscreen is rectangular and portrait, it stands to reason that it will not fit properly if allowed to rotate. My Samsung Tablet Live Wallpaper does that when I turn it portrait. It only goes down ¾ and then black. How did you change it, enable it to rotate, and ...why? :confused:
[Motorola Droid RAZR] morr22066:
Lock screen

I like to use the daydream setting so I can use the clock as a desk clock and alarm clock while it's plugged in. I go into display settings and enable auto rotation. And I use the theme engine to set the lock screen wallpaper. I usually use Nova for my home instead of Google or Apex. I could go with no wallpaper and just have a black screen but I like having a wallpaper that matches my theme.
[Motorola Droid RAZR] GTiceman:
Thanks for the reviews on 5/20. I haven't been posting because I haven't left 5/14 but I am jumping to 5/22 now. Will report back if my phone blows up .... or if it doesn't
