S9920 Repair Update

A while ago I wrote an article regarding S9920 handset, covering some of the short comings of the S3 Mini clone. I have to say since I writing that article, I have received messages from several of you. Many asking if I had figured out how to fix the phone and where to source spare parts. Sadly I wasn’t able to offer much help. Aside from a few threads regarding rom’s, there isn’t all that much on-line covering this device.

After writing the article, not much has happened. The phone has sat in my desk drawer awaiting its fate.

So what has changed you ask? Well recently I did a little on-line research, to find out whether anyone had figured out a way to resolve the problems with the S9920. Namely the ghost touching, which almost renders the device useless as a phone. As it transpires, there might actually now be a fix.

The information I found wasn’t posted one any forum, nor was it that easy to find. In fact when I came to write this article, it took me almost 30 minutes of retracing my steps before I found the original source. So if you’ve been looking recently and not found anything, seriously don’t be kicking yourself, it’s easily done.

The original author of the fix, user “Speedylaci”. Believed the fault with the touch screen resided in the cable connecting it to the logic board. More specifically two solder points, which they believe are weak and causing a bad connection. They suggest disassembling the device and reflowing the two points. Other posts I have read suggest using a small amount of glue to fix the digitisers connector down on to the logic board. After some users observed the connector comes off too easy and could contribute to the digitisers odd behavior.

If you have not performed or read about the fix previously described on ByteMyVdu, now might be as good a time as any to check out the following link and familiarise yourself with it. Needless to say the fix outlined in the aforementioned article did not solve my problems. So reading about another possible means to fix came as welcome news. Better still that it is a very easy repair to perform.

Following the instructions from my previous article, unscrew and remove the back panel of the phone. This should now leave you with the PCB and camera module exposed (see fig 1). Above the power button you should see a small cable connected to the motherboard, this is the connector for the LCD which needs securing in place. It is up to you how you do this, some people have used glue, others adhesive tape. If you decide to use glue, keep in mind that too much could irreparably damage the phone. The last thing you want to do is gum up the connector and prevent it from making a circuit. A little glue on the outside between the connector and the cable should be fine. Leave it to dry before re-assembling the device.

With a little luck this might improve the digitisers performance, it certainly can’t make it any worse. My handset had been sitting in my desk drawer for over 6 months, so I didn’t care whether it worked or broke the phone even more. The fact is I’d written off the S9920 long ago, so bricking the phone really didn’t worry me. If this is something you’d rather avoid, then I suggest you don’t perform the procedure above. Having performed the fix on my handset, I sadly can’t tell you if it solved my problems or not. The screen has not acted up since doing the repair, but given that the fault occurs randomly, only time will tell.

 

Keep on Geeking!

    I had the same problem during all last year, from time to time it just stopped behaving, I even had months with my cell working propperly. Last month It began again but this time more persistent than ever. Now that I´ve read your post I am willing to give it a try. Is your phone working fine?

      Sadly the Alps would just not work for me. Either it was a defective unit or as I’m more inclined to believe. The model is designed with inherently flaws that make it unusable.
