Frequently asked questions for Android smartphones.

OTG is a technology designed specifically for the exchange of data between smartphones, electronic devices and peripherals. This was made possible thanks to the wide capabilities of the Android OS, which include support for file systems used on desktop computers. For the data transfer to take place, the phone must support the OTG protocol. Its use excludes the participation of a PC, which makes the transfer simple and fast. The main thing is to pay attention to the smartphone port, it may be the previously known mini-USB, the current micro-USB or the technological Type-C connector. The bright representative of the smartphone with OTG is the Highscreen Max 3 model

The need for this technology arose due to the impossibility of transferring a large amount of data using Wi-Fi or Bluetooth. OTG expands the capabilities of the smartphone, providing comfort and ease of use, for example, to watch photos or videos through the TV screen, you just need to transfer data from the phone to a USB flash drive, which without a PC is much faster. By the way, if the flash drive is formatted in FAT32, this will be the right approach.

Which Highscreen smartphones have capacious batteries?
The majority of smartphones on the market today are equipped with batteries whose capacity is limited to 2000-4000 mAh. Models with higher battery characteristics are called smartphones with a large capacity and their value lies in the range of 4,000 – 5,000 mAh. This volume is usually enough for autonomous operation in intensive mode for 1-2 days, or for 2-4 days of modest operation. Being the founder in the development of smartphones with a large battery, Hayskrin always has capacious mobile phones in its assortment, at the beginning of 2020, these are:

How to block a subscriber?
To block unwanted calls, you can use one of the third-party applications by downloading it in the Google Play store. In this case, thanks to the application, most advertising or unreliable calls will be blocked at the stage of dialing to your number. Android OS itself provides the ability to add to the Black List any number that you do not want to receive calls from. To do this, go to “Contacts” or “Call Log”, find the hated number and hold the popup menu for a long time, from which you need to select “Add to the black list”. Or, keep displaying the number of the unwanted person, and select its blocking in the opened submenu. After that, all calls from the specified subscriber will be reset automatically.

How to increase the font in the menu?

Depending on the model under consideration, further manipulations may differ slightly: in the first case, in the presented list of settings you will immediately find the necessary item “Font Size”, in the second you must go to the item “Device”, then “Screen” and “Font Size”. Here, the user is provided with several options for font sizes – small, regular (or standard), large, huge. We click on the necessary option and confirm our choice.

How to change the screen saver?
To change the screensaver to a new one, either by a long touch on an empty space of the desktop, call up the menu with the item “Backgrounds” or “Wallpaper”, or through the main settings go to the item “Wallpaper”. Here are some folders with images. This can be, for example, “Local Wallpaper”, “Live Wallpaper”, “Gallery” (a folder with a photo), any file manager, etc.

Selecting a screensaver from the predefined wallpapers, click on the image you like so that it opens in full size, and select “Apply” or “Set wallpaper.” Further, the system will offer a choice of several installation options: on the lock screen, or the desktop, or both screens.

When giving your preference to live wallpaper, remember that animated interactive wallpapers really drain the battery. If you need to install a photo on the screen saver, it is important to make sure that it fits the screen in proportion, if the image is large, the system will offer to crop it.

Do I need to contact the service for flashing software?
In most cases, it is not necessary. The very possibility, the files for flashing, are provided precisely by the manufacturer of the device. Although, a number of manufacturers prefer not to give data to customers, recommending that all the manipulations be done through their service centers. The Highscreen brand takes care of customers, and instruction files that may be useful to users are publicly available on the technical support site. Thus, if it becomes necessary to update in the event of a software failure, you can do it yourself without resorting to the services of service centers, the main thing.
