Hello everyone! My screenshot / back cover solution.
Step 1: Check the phone squeezing in different places of the screenshot (I have 4 corners of the phone);
Step 2: Remove the lid, remove dust;
Step 3: We take the anti-script (sold in many auto shops, but because we need a very little much easier to ask in car services around the house, in the installation centers it is definitely) and cut into small squares;
Step 4: glue to those areas that cause the creak, in this case it is the corners of the phone;
Step 5: Enjoy)

PS: Passed for almost a month as I pasted the anti-scrip. Everything is cool, but for the future cut smaller squares than me. I pasted a bit too much and the lid became very easy to remove, even sometimes together with a silicone case. I made myself smaller and everything is fine!

Hello. I got myself a Lumia 640 DS 3G in the value of the old 920. Not passed and the week, chose a random earth screen. All the same, 920 was noticeably stronger and survived not one dozen drops on the asphalt, concrete and tile.
Tell me, please, where you can checked the original display with the touchscreen assembly?
On "Ali" statements of sellers about originality do not inspire confidence. Thank you.

Friends, tell me this device to buy or better nokia 730?

In principle, there are not many differences.

640 has better screen color rendition, but worse viewing angles and less brightness.
640 perfectly works GPS, 730 worse accuracy.
640 has a little better quality of the conversational speaker, but because there is no second microphone, then in noisy places it gives it worse.
Due to the lack of additional. Microphone 640 wrestling the sound when recording video.
The camera in 640 has a greater permit, but optics look like worse than 730, so I like the photo more than 730.
The battery lives approximately the same. The assembly is also similar.
Oleophobic coating is better at 730. Plus that I do not like 640, the fact that the screen is strongly mirror, in 730 an atyboy coating is better.

And so look in size, design.

Overnight passed 2% of the battery charge. If you are subject to tests, it turns out that I have a battery like everyone else, and does not need the exchange.

I had a question, whether the battery and data transmission affect the flow rate of the battery. Perhaps more economically will turn off the transmission of the data when it is possible to connect to wifi and turn off the WiFay when there is only connection through the operator? And then I always have both Wi-Fi and data transmission. But on the street only the sign of the transfer is highlighted, and only Wi-Fi. They work in the background, or still automatically off. and incl. yourself?

I think it makes no sense to disable data transmission when Wi-Fi isneed, because If there is the last transmission of data on the cellular network is not used. You can disable Wi-Fi on the street (if you use only the data transmission over the cellular network) to reduce the energy costs to find available Wi-Fi networks. I usually do not turn off, one charge is calmly enough for a day with an excess with moderate use of the device.

Surely such a consumption is not due to the data on the movement. You have an active style of use, most likely. Describe an exemplary use algorithm, let's see. I, for example, listening to music all day at work and I have enough charge, too, for a day, truth with a margin.

Disconnect the Internet connection, go to the time settings and dates, turn off the automatic setting, set 2160, then go to the "display" item, will offer to remove or buy, delete the real date, in the market, you download the SysApp Pusher application, in it, in the section Microaoft Look for the display "Display" and install it. Try to try

Constantly included location and 3G Internet when at home, then Wi-Fi. Basically I use the FB messenger. There are not many surfing on the Internet, a maximum of 30 minutes. Applications that work in the background almost turned off. At night I charge up to 100%, in the evening barely enough.



Rep: (336)

Never considered the presence of HDR in a plus chamber. And in general it applies not to the camera, but to software. But if you already need it, then put a third-party camera in the apparatus, for example Camera360 and use.
And so 730 less ha and distortion. Yes, and the transfer of halftone is better.

Just the application "Health and Fitness" from not strongly consumed the charge. Also demolished it, put Fitbit instead - the battery began to flow noticeably faster.

Try to change the messenger. Perhaps he is eating a battery. Actually, you can see who is to blame, in the control of the battery it is shown someone how many percent batteries talked.
