Simple answer: Yes, but it's usually not noticeable and won't impact a device's ability to function as expected during it's lifetime. Full Explanation: Apps CAN leave traces of information behind when uninstalled.

The official Google Developers site has the full instructions and image repository on how to install a factory image for any Nexus device, including your "nakasi" Nexus 7 2012. I recommend 4.4.4, but you are free to go back as far as you want until you're comfortable with it's use. Cyanogenmod also has a stable 10.2 version (Android 4.3) - you can download ...

I understand that read/write speeds are dependent on what the phone is, and what the SD card is, but since both are flash memory, I thought the read/write times would pretty much be around the same. That is a wrong assumption. While they're all flash technology, there's a very wide certain in the speed of the storage. A Class 2 SD Card has a minimum ...

The launcher usually is considered to be the homescreens and app drawer, and they come in all sorts of flavors and designs. When you hear people talk about "stock" Android, this usually is what they're referring to -- homescreens and app drawer unchanged from what Google includes in the open-sourced code.

A launcher, in simple terms, is an interface for your home screen; it determines the appearance of it, if you like. If you were to install a 3rd party launcher (Nova is quite common), it would not run on TouchWiz, nor would it uninstall it. If you do install a new launcher and want to go back to using TouchWiz, it's just a simple matter of tweaking a few ...

Resetting a Device that's Off Power down your device. Before you begin the reset procedure, you will need to completely power your device off. (If the device is frozen, you can pull the battery out to turn it off.) Press and hold the recovery buttons. The buttons vary from device to device, so you may need to look up the instructions for your particular ...

Do you have an external sdcard in your device? If so, remove it and try again. When sdcards start throwing errors and have to remap sectors it kills their performance. As this is usually an indicator for a dying sdcard i would suggest to backup any important data you have on it.

I used samepage merging a long time ago until I just recently updated my device and back then it worked perfectly. There were no problems regarding speed, errors (no graphical artifacts, inaccuracies, bricks etc.) or safety. Samepage merging merges two identical portions of data in RAM to the same memory pointer which then saves the extra amount of memory ...

According to Wikipedia: High Speed Packet Access and Evolved HPSA, HSPA+ has a theoretical maximum download of 84 Mbps and an upload of 10.8 Mbps. Using Dual Cell Technology, it can be doubled to 168 Mbps download and 22 Mbps upload. This suggests that the upload speed will not be anywhere close to the download speed. Doing a search for HSPA+ 21 Mbps, most ...

First I would jump into the developer options and play around with rendering settings in there. This is going to pertain to the GPU probably a lot more than the CPU. You can also enable some helpful rendering overlays to get visual feedback regarding touch areas, rendered areas, and gpu utilization. Unfortunately I can't say that one particular item or ...

This is probably a bug in the custom ROM you've installed. You should report it to the developer of the ROM, and either wait for it to be fixed in an update, or use a different ROM.

If the logs are really bothering you, you can deal with it two ways. Options one is to turn them off. You can do this with adb shell setprop log.tag.BadTag ERROR That will only log them if it's error or higher, but you'll have to kill the application before it'll listen. The second option is to use logcat directly and filter out what you don't care ...
