not for long If without disassembly, it is not drying at all. Moisture remained there, and over time will do its job

[Astraport2012]

The phone stopped seeing sims. It seems like one contact broke off.
Is it possible to repair or is it better to order a module for SIM cards? If the second, where exactly?
Thank.

[shiran]

Astraport2012 @ 09/05/18 11:07

Is it possible to fix

Of course you can, you need a hairdryer, a soldering iron

[Golfimbul]

Astraport2012,
There was also a problem with the SIM card slot. If you buy yourself a new one, then here I can recommendAli. I bought this one myself, I came up clearly. Specifically for this phone trays then did not find, but this one came up. You can change yourself if there is a hairdryer, or in any repair shop. If there really broke off the contact, then there is nothing to repair, you need to change.

Golfimbul @ 09/11/18, 14:45

I bought this one myself

why exactly this one? there is much cheaper

Golfimbul @ 09/11/18, 14:45

in any repair shop

if you repair in a workshop, you don’t need to buy anything and wait for it to come, the craftsmen will pick up

Golfimbul @ 09/11/18, 14:45

You can change yourself if you have a hairdryer

What did I write? why repeat that?

[Kolbas]

.... Star Tracker - Mobile Sky Map:
https: //play.google.co...com.PYOPYO.StarTracker

Everything works except for one, but an important thing - the star map does not move after the movement of the phone. Why is that?

Let me join the question - a similar problem. I tried all versions, starting with the most ancient. ASUS tablet, 4th Android

Hello, managed to find a normal one?

Can someone, an analog prompt, please? The phone has not been released for a long time and all the batteries on sale in 2014, or even earlier. Maybe some analog fit?

[shalagram]

Norm the battery sent is sold. I did not find the release date, it is charged by 15 percent, probably not fresh. But it works fine. And the question is, it was in the subject, but there are many pages. In the manager, 5.8 GB of memory. Is this version 4 or 8? Or a mutant? And what prog is better to give the superuser, of. firmware is worth it.
