"Project Butter" is Google's name for the UI latency enhancements implemented in Android 4.1 Jelly Bean. Any Android device running Android 4.1 or later will have those enhancements. Remember, though, that software is only part of what makes an interface smooth and 4.1 isn't a cure-all for lag. Slow hardware will result in a slow UI regardless of the OS. ...

All antivirus applications on all platforms will impact the performance of the device. This is because they intercept your actions and check them for unwanted effects. You say you have installed anti-viruses - plural. If you install more than one such application on any device they will start to check upon each other. This will have a significant ...

Setting this option forces Android to stop each process as soon as it is empty (that is, when no services are started and no activities are on screen for that app). To be clear: this option won't stop apps that would normally run in the background from doing so. Your mail client will still run periodically to check mail, if it's configured to do that. Apps ...

There is an article that discusses the semi-technical reasons/issues that have lead to the differences in smoothness of Android and iPhone devices. But after gathering some key points from the article one can conclude: From the very start, IOS had been built around a multi-touch screen (meaning IOS had been built from the gound up to be very responsive ...

This is likely to be caused by one (or both) of two things. 1: Your phone does not have TRIM support - something that was only recently added in 4.3. This makes some devices slow down significantly over time - notably the 2012 Nexus 7 - and they stay slow even after a factory reset. 2: Aging flash. Depending on the quality, type and age of your device's ...

While this might appear to temporarily "speed up" your device, this kind of "Chuck Norris Roundhouse Kick" is rather contra-productive for the system, especially for two things: your battery load time to access one of the killed apps again Android usually does a good job managing ram. But some apps sometimes make it hard to do so (mostly by not behaving ...

You are absolutely correct in stating that the bottleneck is actually not the encryption/decryption but NAND write rate. In fact, the performance observed for read/write of encrypted v/s non-encrypted does not vary significantly owing to high cpu speeds. What you might look at though is the rate at which block level encryption happens for the first time. ...

The YouTube app has been and continues to be a laggy little dingleberry. Here are a few things to try: Is there the same level of lag when you try to load the video from youtube.com? Have you tried an alternative YouTube app like Viral? When updating to the latest nightly, do you clear your Dalvik cache?

In theory, your phone should perform considerably faster with CyanogenMod 11, because KitKat was designed with entry/mid-level phones in mind; requiring only 512 MB of RAM to run. (See this page about Project Svelte for more information.) CyanogenMod also adds a whole slew of features like Heads Up Notifications and Privacy Guard on top of the AOSP code, so ...

My HTC One V was getting so slow that I was getting ready to smash it. After trying everything with nothing working, I went through my apps and deleted a few. Apparently the one causing all the trouble was You Don't Know Jack. The second it was off my phone my speed dramatically increased and started functioning normally again. Not sure if this will help ...

When the screen redraws, that is usually a sign of low memory. Considering this device is 3 years old, has 768mb of RAM, a 1GHz single core processor and running an Android version that was never even released for the phone, lag is going to happen. Chrome and Opera are both very memory hungry apps and since your device has a small amount of memory and an ...

It's impossible to tell, the effect of overclocking varies depending on the specific software and hardware. However it likely won't make any notable difference if you're only getting 7fps in a game. Overclocking is highly unlikely to make an unplayable game improved to the point where the game becomes playable, except in very rare circumstances such as ...

I was facing the same issue after the 4.2.2 Feb 6, 2014 update. Did a factory reset and I'm able to run applications now. The dialing and answering the call problem is resolved, but on the whole, the mobile still lags.

Crossbreeder is a great addition to any Android device. It does a lot of things, among them: DNS caching and paralleling, ad and spyware blocking, modulation of OS entropy levels. It helped A LOT when I had an HTC One V [1.5GHz CPU (OC'd), 512 MB RAM, Android 4.2.2]. So much so that I also flashed it onto my Nexus 5. Greenify helps by allowing you to ...

I had the same issue. So, after a lot of work and tests, I've discovered that what was causing the issue was the Prey app. Do you have the Pray app (or similar) installed on your device, perhaps? After I've removed it, the dialer came back to work normally. Hope it helps.

For low GPU workloads, the only sensible metric is power consumption. If the frame time is always less than 1/60 s, then changes in frame time won't affect the visual appearance of the app, so neither frame time nor FPS provide any useful information. You can't usefully measure power consumption from a user-space benchmark: you need either kernel hooks (such ...

You shouldn't worry about ART or Dalvik since you have no control over which one they are using. Assume they are using the slower one and go from there. ART is far off anyway and even after its out as the default for android it will still probably be years before its the biggest chunk of the market. And ART is still in beta so who knows how good or bad it ...

Android logs are stored in an internal ring buffer. As such, I don't see how even the overly verbose apps could slow the system down purely through logging.

I'm thinking a factory reset could do the trick for you. Make sure do backup your things with something like Titanium Backup.

Such symptoms have often been attributed to the eMMC chip (which is in fact a small SSD that runs a flash translation layer (FTL) software). Android 4.3 added TRIM support to address this. There exist solutions like LagFix (fstrim) that run on rooted devices and essentially do the same. Cyanogenmod's Wiki has more information on buggy eMMC chips. However ...

Do a system wipe and reinstall. This significantly sped up my Sensation.

There is an app called LagFix, which can let you trim your device literally. It can only run if the device is rooted, and since your device is already rooted then it is perfect for you. And here is the thread on Xda developers about LagFix. I hope it helps.

You could try to use some live monitoring app, e.g. OS Monitor. These usually offer you a view on apps currently consuming most of the ressources, e.g. hogging your CPU, eating your RAM, or utilizing your network: OS Monitor showing running processes, and showing network connections (click images for larger variants) Running processes can be sorted by ...

The official Firmware runs Touchwiz, which is a known Resourcehog, in addition to 2.x having known occasional performance issues with the Mediascanner. I recommend flashing the latest stable CyanogenMod release. Although you will sacrifice a few features, such as FM Radio - which can be restored with specific Kernels and Apps which use the functionality, ...

I have had very similar problems with my phone. The response I got to my query on the whirlpool forums seemed to have fixed it. (I had apps closing, the keyboard not appearing or closing, etc). Go to settings > power Untick fastboot. Power off then on your phone. This saves a hard reset if it works, which it did with me.
