Question: Flickering dots on the desktop and when working in the browser

Answer:

Message from Metalzon

Proidoha, I doubt it's the cable

In vain, that's the first thing I thought of. Honestly, I have no idea whether there is a difference in the cable cores involved during idle time and under load, try with a different cable - this is the simplest thing that comes to mind.
You have problems during idle time, perhaps the minimum state of the GPU needs to be raised, or the power supply. I've never overclocked cards, and I don't particularly like MSI.

Websites are opening, VK, Face, Skype, etc. are working.
There are no notifications at all: mail, VK, Skype - everything is silent.
Play Market works until you enter the application page. or rather, not even quite like that - you go to the page, the content is shown for about half a second, then the message “Check your connection and try again” pops up.

Has anyone encountered this?

Answer: In fact, the problem was not in the router, because... The phone that “came to visit” did not have our problems. It’s strange that all the “home” devices just stopped working with amazing unanimity.
I’m describing what was done based on recommendations from various sites and forums in order to bring wi-fi back to life (I didn’t even consider options with an evil virus that had settled in me):
Triple checked the time was correct.
deleted Freedom program, PRIORLY STOPING it. Rebooted the phone. After this manipulation it worked Google Play Market.
cleaned it Hosts file, leaving only 127.0.0.1 localhost in it. Rebooted the phone.
I went into the applications, stopped "Google Play Services", deleted updates, rebooted the phone and after that (OH A MIRACLE!!!) the wi-fi turned white and began happily bombarding me with notifications from all applications. in the process he pulled it on himself remote updates "Google Services Play".

The same thing was done on the second phone, but there was a problem with the keyboard: after the update it started throwing an error. I uninstalled keyboard updates and unchecked auto-update.

If an android appears on the screen with exclamation point, this means that it was carried out failed experiment with the device software. This may have happened due to the installation unlicensed program or after switching from original firmware to custom.

Hard reset

This action is carried out in the device’s engineering menu and allows you to return your smartphone or tablet to its original settings, which is very useful when the android lies with an exclamation mark. Special engineering menu called by pressing certain buttons, but there are some complications. Models different manufacturers The key combinations are different. Specific sequence present in calling the engineering menu.

The device must be turned off. It is best if the battery is fully charged. For most gadgets, the following combinations of buttons to open the menu are suitable:

1. The Volume Down key (or Volume Up key) is pressed and held together with the Power button.
2. Both sound control keys are pressed and held, and then the power key is pressed.
3. 3 buttons are held simultaneously: main screen, volume up and power.
4. The Home key is pressed together with the sound control key down, then the Power key is pressed. You must wait until the manufacturer's splash screen appears and release the Power button. After the robot image appears on the screen, you can release everything and wait for the engineering menu to appear.
5. Press and hold the power button for 2 seconds, then hold down the sound control keys and the power button and hold until special menu.

After this, the gadget will either restart and return to factory settings on its own, or an engineering menu will appear. Please note that in this mode touch screen does not work, all menu navigation is carried out with the sound control keys, and the selection button is the power key or Home button. You must select “Wipe data/Factory reset”.

Several lines and a question will appear on the display (“Delete all data from your device?”). You must agree, after which the device’s memory will be cleared.

Reset on different devices

On smartphones and tablets manufactured by Samsung, entering the engineering menu is done by simultaneously pressing 3 buttons: the key to call the main screen of the gadget, the volume up key and the power button. Resetting to the original settings is done using the Wipe data/Factory reset item and then rebooting.

HTC devices, when Android with a red exclamation mark appears on the display, can be brought back to life by pressing and holding the power and sound control buttons. When Warning appears on the display, you can release everything and press the volume up key. On some models, hold down the volume button and press the power key until an android robot appears on the screen. After it appears, you can release the buttons and press the volume down key again. A menu will appear in which you need to select “Restore original settings”.

A menu will appear on the screen where you need to select Recovery Mode and press the volume down key. An android with an exclamation mark will appear. Now you need to press the power button. A menu will appear where you need to select Wipe data/Factory reset.

And on the tablets of this company, you need to move the screen lock lever to the left position, press and hold the power button and sound control keys. When the tablet starts to vibrate, you need to change the position of the screen lock lever several times until the words Erasing Userdata and Erasing Cache appear on the display.

After the time has passed, you can release the power button and hold the volume down key until a special menu appears. There you need to select Enter recovery mode, then Wipe data/Factory reset.

Device firmware

If hard reset did not help, a complete software replacement is required. But there is a formality here: the firmware will only help if the “USB Debugging” function has been enabled in the device settings. This method is quite risky and the slightest violation of the instructions can lead to damage to the device.

Here it’s worth thinking about: should you try to restore the device yourself or trust the professionals? But if you decide to flash the gadget yourself, you should carefully study all the available information on this issue. Models from different manufacturers have significant differences and features regarding software changes.

In general, the process of replacing software looks like this: download the file with the firmware, study installation information, read reviews about this firmware version. Next, the file should be unpacked into the root directory of drive C and, if necessary, install drivers for the gadget. After this, the device must be turned off and using a key combination (usually a combination of the power button and volume up) switched to firmware mode. Then you should connect the device via cable to the computer and follow further instructions of the program. At the end of the process, you must perform a hard reset using the engineering menu.

G or E icon on the phone screen on the left top corner what do they mean?

This means which Internet is connected with the letter G - the phone signals that GPRS is connected, and with the letter E-EDGE, and in addition to these letters, 3G, 4G, H, H+ can light up. If you have G or E, then the Internet is very slow and it takes a long time for the page to load.

Now, at the beginning of 2017, such an icon ( G PRS or E DGE) means you have a very old mobile phone with very slow internet, and of course, an unusable browser. Using such an Internet is a torment now, when 3G already seems incredibly slow.

The G and E icons in the upper corner of the phone screen mean that the Internet is connected. Such icons appear on screens modern phones, smartphones.

The icons indicate the data transfer speed. How larger letter, the higher the speed.

G stands for the most slow speed, denoted by GPRS.

E speed is twice as high, designated Edge GPRS

There may also be 3G icons (third generation speed, video viewing is not possible high resolution), 3G+ and H speeds are even higher, H+ is even higher, and LTE is the most fast speed 4G.

Usually this letter is located next to the prima level indicator. The letter G means that the phone is connected to a network using the 3G standard, which provides data transfer at an average speed of about 4 Mbsec.

The letter E indicates that the phone is in at the moment switched to the EDGE data transfer standard, in which the data transfer rate is limited to 384 kBsec, which is approximately 10 times slower than the 3G standard.

For the user, this means that the letter G means good prim and good zone, you can use Skype, watch videos from the Internet, download music.

When the letter is E, it means the phone is not in the most best zone prima, or the load on the station has increased, you can’t contact such a letter via Skype, you can’t watch videos, you can’t download music, but just surfing the sites is enough.

These letters G and E mean that you are connected to the Internet or simply activated. Even if you have a very simple phone, it can show this. The letter G indicates a weaker Internet connection, but E indicates a faster one. You may also have 3G and 4G, this is even faster Internet.

In addition to the letters G and E, other signs may be shown at the top of the screen: 3G, H, H+.

The signs G and E indicate network connection standards. G is the lowest standard of the GSM protocol. E is for Edge and it's more fast internet. Well, 3G is an even more powerful connection.

The G or E icon on the phone screen in the upper left corner of the screen means Internet access networks: G-GPRS or E-EDGE. When these icons are lit, it means the phone can access the Internet through a specific network. It is worth noting that E-GPRS will provide you with greater speed.

If the icon is displayed, then the phone is connected to the Internet or has simply received a signal from a certain network, since you say that you have a simple phone.
