Google nexus 7 slows down after update.

More recently Google company released the long-awaited update android 5 Lolipop for Nexus7. Oddly enough, even the oldest models of the Nexus line have been updated. This once again speaks of Google volume not HTC or Samsung (users are not scammed with updates), but many users of the very first Nexus7 2012 noticed brakes in work android. Knowledgeable people of course they know that the circle in the form of the number 0 in name Android 5.0 says that updates are already being prepared, in which all the glitches that have arisen in the first versions are traditionally eliminated. But you need to live this time somehow, and if religion does not allow you to roll back or set it to custom, then these tips will be relevant:

1. After flashing it is recommended to do full reset systems with overwriting the entire tablet. This will remove some of the glitches in the work. If it doesn’t help, then feel free to reset it again, or better yet, do a complete reset of everything as Google recommends:

Turn off your Tablet PC.
Press and hold the Power and Volume Down buttons at the same time until the device turns on.
The word "Start" will appear on the screen surrounded by an arrow.
Press the Volume Down button twice to highlight Recovery option mode.
Press the Power button to activate this mode. The screen will appear Android logo, red exclamation mark and the inscription "No command." (No team).
While holding down the Power button, press the Volume Up button.
Use the Volume buttons to find the "wipe data/factory reset," option and select it by pressing the Power button.
Go to "Yes - erase all" user data," (Yes, delete all user data) and press the Power button.

2. If you installed the launcher Google Start, so that everything is the same and in Lolipop style, then you can safely delete it. It was not for nothing that Google left the old launcher in the firmware. With the new one, Android 5 on nexus7 slows down even more)))

3. If you have not yet activated the “developer” menu item, you can do this by clicking several times in a row on the build number in the menu with information about the tablet.

4. After activating the developer section, you can play with the settings that are there. For example, turn off all animations or, on the contrary, make them larger so that while the screen is changing, the information has time to load. Even lower there is an item that allows you to set the number of applications running in the background. This will also help reduce the load on the tablet.

5. You can also make your tablet’s life easier by disabling applications that are constantly trying to synchronize or run in the background. For example " Google Search". You can do this by going to the program section, selecting the "all" tab and going to the desired one, click on the "disable" button.

Finally, the main advice would be to just wait. Applications are cached. Developers are gradually optimizing old applications for the new OS and they will work faster. Google always releases a corrective update and this time will be no exception.
Have you already updated your Nexus to Android 5 or not yet?

Everyone who has switched to MacOS and does not want to use a magic mouse, well, for whatever reasons, is faced with the fact that mice from third party manufacturers are behaving somehow wrong.

It was new, everything worked very quickly on it. The response to clicks and touches was immediate. Then I began to notice that applications took a long time to launch, the keyboard for input came out after a minute, in general, the tablet slowed down and it became impossible to use the device. What should I do, should I buy a new one?

When I finally got tired of this braking, I decided to figure it out. First thought - new Android versions, which are regularly automatically installed on the tablet, simply require more modern hardware. As it turns out, this idea is wrong and new tablet no need to buy! Everything slows down for a completely different reason.

The fact is that memory space is divided into areas. For example, there is a zone user files, official, etc. For simplicity, I won’t go into details, it’s enough just to know that there is a special memory space where the operating system stores cache files for quick access and speeding up the work, just so that it doesn’t slow down. When an update arrives, files from the new operating system are added there. For example, if there were three OS updates, then cache files will be stored there for all three versions. But for older versions, which we no longer use, these files are no longer needed, but they are still there.

So, the memory area, which is designed to improve performance, is cluttered unnecessary files from older versions of Android. Naturally, instead of increasing speed, degradation occurs and the tablet slows down more and more. We should erase them. But in regular menu There are no such items or buttons. But there is service menu, where you can painlessly go and delete these files, the main thing is to know how.

How to access this special service menu? First you need to turn off your Nexus 7. Then press the power and volume down buttons at the same time. If the tablet starts to boot as usual, it means you pressed the wrong button. If everything is correct, the tablet will start up in special regime and will display the image:

A robot is drawn with open lid. At the top you can see a menu with the word Start. You need to use the volume keys to move this menu to the position Recovery Mode and press the power button (it appears here as OK). After this, the menu will disappear, and the message “No command” will appear next to the robot:

Here the tablet awaits a command from us. It is introduced in a very interesting way, be punctual and careful here. You need to simultaneously press the power and volume up keys and hold smooth 3 seconds. If you underexpose or overexpose, nothing will work. When you have waited 3 seconds, release the buttons, another menu will appear on the screen:

Here you need to select “Wipe cache partition" Choose this item carefully, because there is another one next to it with the word Wipe. Press the power button and the process of erasing our cache begins. This process ends quickly, after 5 seconds, displaying a message in the lower left corner of the screen:

Next, in the same menu, select Power down, and the tablet turns off. You can turn it on as usual and evaluate the performance gain after loading. Your favorite Nexus tablet 7 will be as fast as when it was new!

Current versions of the software can be downloaded from 4PDA. http://4pda.ru/forum/index.php?showtopic=485455

In the evening the Nexus 7 2013 tablet froze, so I left it and went to bed, by the morning it was discharged, and after installing it on charge it always showed the loading picture. After a day of suffering, the problem was solved.
Googling for a minute
1) install firewood to work with the device in fastboot mode.
2) Unlock the bootloader (correct me if this is not necessary for the command described below)
3) Download the program to work via fastboot+adb.
4) Enter the device into Fastboot mode(when turning on, first press power button and hold it, then after a second press and hold the volume down button)
5) Launch the console, make sure that the console sees your device: fastboot devices by entering this command, the serial number will be displayed.
6) Run the command: fastboot -w wait until it is executed, this will erase the user data and replace it with factory data.
7) reboot the device and wait on the splash screen for 30 seconds, after which it will turn on.
Which probably solves 99.99% of the problems, but the whole trouble was that the recovery also refused to start.

1. You need to install drivers on your PC. (8.82 MB), the version from Windows 7 fits Windows 10 without any problems.
2. I unpacked the files to C:\Android\Tools
Then we go to command line Windows with administrator rights.
3. Enter Fastboot mode (Hold down the power button and volume-up), connect USB.

C:\Android\Tools>fastboot devices (checks whether your device is connected, it should show)
08xxx060 fastboot

4. Unlock the bootloader, go to the directory cd C:\Android\Tools, after C:\Android\Tools> fastboot oem unlock
5. Upload the recovery file to the C:\Android\Tools directory and install custom recovery for your device
fastboot flash recovery twrp-3.0.0-0-flo.img

6. Try going into recovery
I didn’t succeed, the same eternal loading... I managed to force start the recovery fastboot command boot twrp-3.0.0-0-flo.img , in this case the tablet could freeze, go into recovery when trying to force shutdown (by holding down the shutdown button) or when next turn on, BUT I CAME IN THE SAME)

7. Next, it remains to install the OS, all options for nexuses are on the off site https://developers.google.com/android/nexus/images
But that was not the case... All attempts to install the OS through the SkipSoft ToolKit program or with the command
C:\Android\Tools> flash-all.bat (after unpacking the tgz archive, in which there is also an archive in which there are several files and a zip archive of the firmware, these several files and the zip archive (we will NOT unpack it) must be placed in C: \Android\Tools to other files)
Everything is fine, but not for me... as it turned out, the tablet refused to set them to failure, the eternal download remained, and often the files did not load at all and the entire system weighed 14MB =(

8. I had to boot into recovery, after which the laptop saw the tablet as a storage device and I was able to upload third party image OS under recovery TWRP https://www.androidfilehost.com/?fid=24399994186366980 Bad_Boyz_Nexus_7_MMB29K_6.0.1_stock_systemless_rooted_TWRP

Installation this image allowed me to solve the problem eternal loading, the tablet still showed the image from the Google download, but after a minute the download of OS 6.0.1 began, lasting about 7 minutes. Surprisingly identified as Nexus 2012 but it works :)
___________
Upd, now the touch refused to work, as it turned out - physical breakdown, I decided to open the tablet because after pressing it at the contact points of the cable, it turned on itself and responded to touches.

1. Using a plastic card (I used a Pokemon chip since my childhood), gently press the volume rocker between the plastic cover and the glass just below the volume rocker, swipe it down, then up and through upper part let's go to the other side.
2. Turn off the power.
3. Open the latches on the bottom and top sides and carefully pull out the cable.
Surprisingly, it was in perfect condition. We collect in reverse order, we rejoice)

If your tablet computer Nexus 7 does not turn on, hangs on the boot screen, or does not give any signs of “life” at all after one action or another, then you should not immediately despair. As practice shows, in most cases it is possible to restore a seemingly completely “dead” tablet.

How to bring your tablet back to life?

So, as the first step in the Nexus 7 recovery process, we need to launch the so-called “fast boot” mode. To do this, with the tablet completely turned off, you need to simultaneously press both volume buttons and the power key and hold them down until the following image appears on the screen:

Now release all previously pressed buttons using a USB cable. operating system The computer should recognize it, but if suddenly this does not happen automatically, then you will need to install the drivers manually. You can download them to your computer on the forum.

The main menu of the nexus 7 toolkit looks like this:

Select item “9” called “Download, Extract + Flash Google Factory Stock Rom.” This item is responsible for loading and automatic installation stock firmware from official servers Google.

After that we will get to this menu:
