Question

iPhone

Hello. I decided to buy myself a used iphone 4. Tell me, please, what should I pay attention to when inspecting? Any bugs that the seller will try to hide? What is the best way to assess his condition?

Answer 1

1) Battery capacity - during normal operation without 3G, it should be enough for a day and a half
2) The work of all radio units - GSM, 3G, WiFi, Bluetooth
3) The work of touch - especially at the edges and in the corners, and also check multi-touch
4) Home button operation - press and exit applications the first time
5) Large connector operation - the phone is detected on the computer and charged
6) Camera operation - turns on, focuses, zooms, video
3) Appearance - scuffs, chips, scratches.

Answer 2

But you can’t define a drowned man in any way.

Answer 3

Camera! I only checked the rear camera for photos and videos, I thought everything was ok. Already at home, I found that the front camera does not work and freezes the entire application.

Answer 4

Buttons, battery, radio blocks, locked or simfri.

Answer 5

If the phone is locked, pay attention to the version of the modem: if 04.11.08 (version coming with ios5), then such a device will only ring in the network of the native operator.

Answer 6

On the model (LL Americans), so as not to take the locked one. Check IMEI on the box and body.

Answer 7

Fours have a disease, the microphone does not work when talking. When the recorder is working, it cuts in, but when it's called, it doesn't. The repair is very problematic, it is necessary to reball one mikruha near the processor, but it is difficult to do this because of the compound, the compound pushes the balls out from under the processor.
