I have used the Sony Ericsson W550

The upper cover of W550 is relatively easy to loosen, but the feeling varies from person to person, if LZ is really not at ease, you can change it, but it may be looser in the future Because the design of the screw cover of this machine is not very compact, most of the W550 will have the problem of loose cover.

Or look at the number of flip covers, the specific operation is to press under normal standby conditions: right*left*left*, and then a service item appears, including service information, service settings, service testing, and text markers.

One of the service tests is the clamshell register. Select it to see how many times your machine has been opened and closed.

Ericsson mobile phones display the make date: right, *, left, left, *, left, * keys.

My Soai W550 has been used for 7 months, but it is not loose.

- I've been using it for 1 year. Loosened once. The screws are all falling out.

It's almost all split in half. It cost 30 yuan to send it to the maintenance department. Nailed it.

I don't know when the next pine will be...Huh. The software part of Sollove is so good.

Hardware makes this low-level mistake.

There is no need to change things with old ones.

It's okay, it's possible to be a little looser. The quality of the machine is still okay, rest assured to use it!

It's okay, mine is also loose, but if it's not very loose, it's generally fine.

There was no need to change the machine, my spin out even the nails fell out, and then I took it to the place where the mobile phone was repaired, and let the profiteers twist it, which cost 30 oceans, and the repair time did not exceed half an hour!

It is recommended to take it for repair!

Regardless of the Hong Kong version or the licensed goods, the screws will be loose if they turn too much. Go fix it, Sanyuan. My machine was down to 2 and a half at that time, and it was done in half an hour!

Hope my reply to you helps.

Hello. Basically. If you buy it from taobao, it will already be loose. That's a parallel import. Most likely, it's not brand new. Rather, it is second-hand refurbished.

If you are loose, you can try to change it.

Find a professional repair shop. For example, local after-sales. Pay for it yourself.
