Meizu Pro5 speaker issue - no sound

@halucigenia I will try to use volume up / down when someone calls and it does not ring - I haven't tried that yet. I will let you know. It may be a week before it happens though.
Sometimes I use loudspeaker during a call and then, sometimes, there is this bug that the volume is low even though the speaker volume is setup at max. Then it helps if I hit once volume down and at that moment the volume immediately is back to max (max minus one click of volume down).
Sorry about not posting for so long but I did manage to replace the top earpiece speaker if anyone is interested.
It made little difference as the device still intermittently goes into and out of headphone mode of its own accord.
At least the new earpiece speaker does work when it's not in headphone mode.
After noticing that some calls came through with an audible ringtone over the last few weeks I was just doing a little bit of tinkering with my Pro5 to see if I could get the earpiece speaker working again.
I wondered if the headphone jack was not recognising that the headphone plug had been un-plugged so I opened the phone up and had a look at the mechanism of the jack while plugging and unplugging the headphone plug. Nothing much was visible, even under a magnifying glass, but I could see that the contacts were moving OK. I have ordered another headphone jack just in case this hunch turns out to be correct.
However, I last remembered hearing a message alert during a cold spell and wondering if heat/cold could affect the operation of the earpiece speaker. Could it be that expansion/contraction of contacts due to heating and cooling could affect the mechanism?
So, on this hunch I thought "how could I cool the phone down"? Well, I have a fridge-freezer, that would cool it down, so I placed the phone into the freezer just to test this hunch. When I got it out of the freezer, some time later as I had forgotten where I had just put it for quite a while, it was so cold that it did not switch on until it had warmed up a bit. Anyway, when it could be turned on, hey-presto, the earpiece speaker was working again.
Not very practical, but now I know that if I want to make a call without plugging the headphones in, I just have to place the phone in the freezer for a few minutes.
Now, I just have to figure out which component could be affected by this cooling process...

@halucigenia conclusion: penguins like frozen phones
@advocatux Ha, like it.
Even after warming up for a few hours it is still showing speaker when pressing volume up/down.
I have the same issue with a MEIZU MX4. For me, I think it was related to the OTA3 update.
What I saw is when the sound is not working and I try to put the volume to maximum, it didn't warn you about damaging your ears. But still when the sound is working.
Finally, I am not able to understand when or what switch of the sound
( I laugh aloud at the freezer part )
Well, the phone rebooted itself this morning while it was warm and reverted back to headphone mode only.
So I put it in the freezer again and, again it went back to speaker mode. The ringtone and message received are audible again for now.

@halucigenia I'm starting to worry about your procedure leading to a serious problem with the battery. Those radical temperature changes can't be good for it.
Hi, I had same issue on my Pro5 in dec. 2017. I had switch back to Android to doublecheck but no change. After it I tried to "cold down" method: I placed the phone to fridge (no freezer) for 2-3 minutes and then the "on headphone" sign had gone. it works fine until next reboot or headphone usage.....
My phone was under warranty, so I could send back to seller to repair. They did not/could not give back the pro5, I could choose other brand new phone because there was not pro5 in the shop anymore.
I think, this is a hardware issue and need to repair somehow. I agree with @advocatux , this fridge/cold down method is not healty for phone.
@halucigenia have anyone of you tried to change the headphone socket? Once you open the phone it's easy to take it out and replace it.
On some Blackberry devices there was such a problem as well, the culprit was the headphone jack socket. It malfunctioned ( no sound heard while ringing ) and keep stuck on headphones mode even without the headphones plugged in. Once the dirt was removed or the jack replaced, no problems anymore.
And the speaker is surely a bad contact or broken earpiece, try to get a new one. Even water damage, as some drop can get inside the earpiece and break it.
If the cold makes it work, there must be a bad connection. When the phone gets colder, the water condensing inside the phone, therefore temporarily fixes the connection and it works. Otherwise is just a woodoo.
@stefano Yes, I have thought about replacing the headphone jack and have one on order. Also I did replace the earpiece speaker and that did not rectify the issue. The real puzzle is that after a cooling the issue does not re-appear until the headphones are used or the device is rebooted while warm. Mine has been fine for about a week without me using the headphones or rebooting.
So, I eventually got around to replacing that headphone jack. I had been putting it off as the issue did not happen very frequently, but just recently it has been switching to headphone mode without a reboot. Also as replacing the headphone jack required removing the motherboard I was somewhat trepidatious about it.
No difference though, it still boots up in headphone mode until I cool it down for a period of time.
I will see if it lasts in speaker mode for longer over next few weeks.
In the meantime I have bought another pro5 advertised on amazon as a UK 32GB version. I will concentrate on re-partitioning and putting 16.04 on it.
