I am using an Anker 24W power supply plus an high quality Anker USB cable. A low quality power supply sounds not reasonable to me. Beside the fact that the Anker device is working with an other phone quite excellent …
Looks like FP2 hardware has some issues. That’s why I’ll contact support because of faulty hardware.
While sometimes it is a hardware fault (Bottom Module [USB Hub] or Battery), it’s almost always a cable/charger issue, so I’d really recommend to try some/many different cables. Otherwise you may send in your device just so Fairphone sends it back telling you there is nothing wrong with it and charging you for unnecessary service.
I frequently have touchscreen issues as well.
When I charge my phone, very often the touchscreen only responds minimally or not at all (‘touch’ sometimes works, but ‘swiping’ and ‘holding’ is impossible, can’t really unlock the lock-screen pattern like that).
A couple of times I had the touchscreen not respond at all anymore too. Sometimes directly after a reboot (which sometimes happens randomly without any cause), so I can’t even enter the PIN or do anything else, so I have to open my FP and take out the battery in order to reboot it again, touchscreen worked again then however.
A few times I had the touchscreen not responding when I recieved a call too, witch is very annoying, since I couldn’t pick it up.
I don’t think the hardware-testing is going to do my any good, since most of the time the touchscreen is in fact working properly.
Any other suggestions?
Hi everyone, I’ve read as much as I can on this thread, am now going cross eyed… I also can’t use my FP2 when it’s charging. It did work occasionally, but since the update today, is frozen again whilst plugged in. This could be a coincidence I realise.
Can anyone tell me a charger they use which works on UK 3 pin sockets please. It would save me a lot of hassle just to buy one.
So what you are saying is that it works with some chargers but you can’t name those? You keep shipping the phone without a charger and it’s up to your customers to try different chargers until they find one which actually works? Or they should always take a computer with them to charge the phone? Or just stop using the phone while charging?
This would all be quite funny if it wouldn’t drive me crazy every other day. I tried three different chargers and the phone is unusable with all of them.
This week I experienced exactly the same behaviour with an iPad Air 2.
A colleague and me are supporting mobile devices in our company. There was an iPad that needed an update. The battery was very low so I decided to charge it during the download. After a while it locked itself, just as configured. A little later I wanted to have a look at the progress and was prompted to enter the code.
I wasn’t able to do so. Some touches where correctly recognized, others where ignored or doubled.
Even after several attempts I was not possible to enter the correct code.
Then I pulled the charging cable and everything was back to normal. Putting the cable back in - same erroneous behaviour.
After further investigation wie found out that our nice white cable belonged to a third party charger.
A genuine Apple cable we tried after that nicely did the job.
So this is by no means a Fairphone specific issue.
It can occure with any device-charger-combination.
FP is a small company and doesn’t have the resources to test all chargers. But there is a community list of working chargers.
You can get a charger in FP’s shop, but not shipping chargers automatically with every order reduces e-waste alot.
That is true. Some companies even try their best to make sure that their phones and chargers are not compatible with other phones and chargers. Just so you have to buy their charger/cable after the first one broke (which it was designed to do after warranty ran out).
I’ll put the link to the list of chargers in the first post to make it easier to find.
I’ve been having this screen unusable issue on some chargers on my Fairphone 2, so I decided to buy a USB power meter. In my testing the screen is still usable if the voltage stays above 5V when a current is drawn.
On the chargers where the screen doesn’t work while charging, I’ve been finding the voltage is dropping as low as 4.80 and possibly slightly lower. When no current was drawn these USB outlets give out 5.0 V. With the chargers where the screen is usable during charging the output voltage is normally closer to 5.2V when no current is drawn.
I’m wondering if there’s something in the electronics of the such that when the voltage goes below 5V, even just 0.2 V (a 4% reduction) is enough to cause the touch sensitivity to no longer work.
I have seen a comment from a user on this forum that received a replacement phone from Fairphone, and only one of them (I don’t recall if it was the new one or the old one) had this problem. So it appears that this problem doesn’t occur on all phones.
It occurs on my phone though, much to my chagrin. It would be good to test replacing the bottom module and see if that fixes this issue. Anybody willing to sacrifice € 20 for science?
Well, of course there are no randomized double-blind studies yet, but I think it’s save to say that there is about a 99% correlation with the used charging equipment (charger, cable, plug) when it comes to this issue.
I wouldn’t invest in a study that tries to determine how much of the last 1% is related to the bottom module.
