Speeding up the Samsung Galaxy Note

In my post “Galaxy Note is slow with Jelly Bean?” I was frustrated with the slow down after I updated my Note to Android Jelly Bean.

So far this has helped:

  1. Removing seldom used apps. This phone has a measly 1G of RAM, and many apps cannot be moved to sdcard.
  2. Clearing each apps cache (in application manager). This must be done periodically.
  3. Limiting background processes to 3 or even 2 (in development settings),
  4. Setting to 0.5x the three windows animation scalings (in developer settings). Some say they should be turned off.
  5. For browser, turn off “allow web sites access to location info”.
  6. Removing recently installed apps. These may have had side effects.
  7. Do not keep activities (in developer settings) But this will slow down app startups time.
  8. Use GPU rendering
 

However, the phone is still much slower than when it had the Ice Cream Sandwich Android version. What is still slow? Everything except in app scrolling and use. App switching and setup suffers. This seems to be a memory or cache problem with the new Android update. If it were hardware, the older Android version would have had a problem. The phone has only 1GB of RAM, and this could be acerbating the situation.

Here are some things other people are recommending:

  1. Factory reset: I did not try the factory reset approach. Not sure of backup and restore capabilities. Also, I read some posts that said a reset did not improve the speed.
  2. Move apps from card: Is the memory card too slow? Move the apps back to main memory. I did not try this.
  3. Turn off power saving settings
  4. Recalibrate the battery? Some say this is never necessary, just do a full discharge and charge cycle.
  5. If you have “S Voice”, turn off the ‘open via the home key’ setting (in S Voice)
  6. Is Google Now turned on? See if turning it off has an effect.
  7. Clear memory via the home button. In Android, unused apps do not have to be stopped, and memory is automatically reclaimed. However, one can try clearing the memory to see if this has any effect. Hold down the home key, then in the app list’s bottom, click on the pie shape.
  8. Remove bloatware. If you can’t, try to disable them.
  9. Turn off auto update of applications
  10. Turn off automatic sync. Unless your making money from social stuff, it can wait
  11. Restart the phone
 

You get to the application manager and the development settings via the phone’s Settings menu.
Unfortunately, some of these settings will revert if you turn off and restart your phone. If the above don’t help, the next steps would probably be removing or disabling any newly installed apps. One user even suggested turning off many high end apps like ‘Google Now’, ‘S Suggest’, and so forth.

Legal recourse?
Since this Jelly Bean update was via the approved carrier’s channels, it should be supported. If you bring in your automobile to the car’s dealers for an official upgrade sanctioned by the manufacture, the car should not begin to stall on the highway. But, this is a complex legal issue, I guess. Reference: SOFTWARE PRODUCT LIABILITY: UNDERSTANDING AND MINIMIZING THE RISKS

The custom ROM solution?
Whenever a plea is posted on a forum regarding smartphone issues, some geek will chime in and suggest that rooting and a custom ROM is the way to go. Perhaps, but that is not for the faint of heart and is very complicated. Maybe there will be some advances in this area, for example, see “CyanogenMod for All! ”A mobile revolution” coming [UPDATE].” There is a video on the updater: Install CyanogenMod on your Android Device with the CyanogenMod Installer. Is the Note supported?

Warning

Some of the advice out there and even some urls are “suspect”. Be careful trying to root and install a ROM. If you read closely you’ll find these ROMs are beta and unsupported. Also, the install process can fail and your phone can be bricked.

What caused the slow down with JellyBean update?
In this post the author has argued that the install process without using a reset will cause these issues. In the post, the author also says that one cannot correct a bad JellyBean install; it requires a real ROM flash: “… you want the phone cold/hard flashed to 4.1.2 as if the phone were fresh off the assembly line with no OS flashed to its ROM (meaning they should wipe the ROM, first) ….”

This is the problem I have with all these advice pages on the web, they contradict each other. In this post, the author says something about making batteries last longer that is directly called bogus in other web pages. So, while a minor quibble, I then wonder if the rest of the information is correct.

No information is available from Samsung, this is the standard response on their support page:
“Thanks for your inquiry! Unfortunately, we do not have any information about a future update release at this time. Stay tuned to Samsung.com for information.”

Compute devices slow down
From searching for solutions I did find something troubling. All smartphones slow down after months of use. There should be tools to handle this and manufactures and vendors should be more honest about the capabilities of the actual storage and cpu. I tried a monitoring app but it was useless, same thing for a battery diagnostic app. I guess a smartphone requires a smart user? 🙂

There is an alternative. When you buy something it should be guaranteed to work at a certain capacity. When you buy a car you don’t expect it to start slowing down if you give it normal maintenance and don’t change its major components. That is the tricky thing, a compute device is meant to be extended.

Updates

  • November 3, 2013: Added a section on custom ROM use.
  • May 27, 2013: One thing that is needed are tables or a database of what apps can be removed or disabled on various smart phones. The average user is at a loss in determining what is really needed or not. The often made suggestion to root one’s phone is not really very practical for most situations.
  • Dec 24, 2013: Some buzz on web seem to indicate the first Galaxy Note will not get an Android update. Time for a custom ROM install? Unfortunately, everything out there seems unstable. An example, for the AT&T i717, we have: “This device does not support the newest version of CyanogenMod.
  • Dec 26, 2013: I got a new battery for the phone. Hmmm. It’s faster. I’ll give it a few days of use to make sure it is not a fluke. The original battery was 2500mAh, the new is 2700mAh. Should not matter?
  • Feb 19, 2014: It is not the battery. But, the battery did fix the battery drain issue, and when it does run well, it is slightly faster. Can’t wait to get a new phone one day. 🙁

Galaxy Note is slow with Jelly Bean?

Finally got Android 4.1.2 on the AT&T SGH-i717 phablet, the original Note. Looks great, the graphics are better, sound is clearer, many nice things. But …

One thing that seems slower is switching from app to app. It could be my configuration, number of apps, and so forth. Still looking into it.

Interesting how the ram load increases on this phone after a restart: an initial 450MB climbs to 527MB/743MB. Then when you click ‘clear memory’ you see ’18 applications closed’. Now there is 352MB/743MB.

Updates
May 5, 2013: I got some speed up by clearing each app’s cache. Some app’s Cache button are not enabled.

Is a factory reset really needed?
How safe is that? Sure you can save your settings in Kies, but we all know about backup software, getting things back is not guaranteed. “Full Backup of non-rooted devices” has some an interesting information.

RANT
In the PC world there is a saying “Intel giveth, Microsoft taketh away”. Is the same true in the mobile world? ARM gives, vendors take it away? So much cruft pre-installed, sneakily added, hard to disable or remove, hidden, and so forth. Also, the social frenzy. Must everything be connected. I tried a simple app once, very simple, it wanted to connect to my social network, promptly canceled and deleted. Then there is the location aware “helpers”, really advertising revenue streams and consumerization culture enforcers. No wonder they are talking about octo-cores!
