The only means of upgrading Android on the Pro1x is to flash Lineage OS, an ASOP-based alternative. The current official version is Lineage 22.2, which is AOSP Android 15. https://download.lineageos.org/devices/pro1x/builds https://wiki.lineageos.org/devices/pro1x/install/ https://community.fxtec.com/topic/4223-lineageos-22x-official-release-for-pro1-x-qx1050/

Lineage-22.2-20250811-NIGHTLY-pro1x with July 1st security patch installed smoothly via OTA. MindTheGapps15, and root was maintained. I want to note that even though my Pro1x has working phone stuff, it has never demonstrated the battery drain problem on 22.2.

I don't have any objective way of testing this, but I noticed that the change log for the last update and this one included references to carrier stuff. It seems to me that my phone call clarity has improved. The phone stuff actually worked pretty good for me from the get go. It wasn't perfect but far better than many people were reporting. But it seems, though anecdotal, that it has improved. Unfortunately, I don't really use this phone as a phone, as ironic as that it is for one that mostly works. So I haven't tried in a very long time, which makes this anecdotal report even more suspici

Just to be clear, I wasn't suggesting not using a Pro 1 as a phone should be a solution for anyone. However, my defect led me to a diagnosis of the possible problem with Airplane Mode being a test. 🙂 I'm just lucky my problem doesn't affect me much because I happen to be weird.

VoLTE made no difference here.

Except that, after maybe the first half of 2020, I have never used it as a phone. Same with my Pro1x although, in fact, my Pro1x actually works pretty well as a phone. They are pocket computers for me. I'm retired and don't do a lot of phoning, Mostly the phoning I do is related to my home health care of Mrs. Hook and I use a Pixel 7 Pro on Verizon for that as I need great coverage and reliability for that. 🙂 Other than that, I don't even give most people my phone number. I prefer asynchronous communication.

Yes, I am able to browse (wifi turned off-- it is actually quite fast) and I was able to take a picture and then text it to my Pixel. The only thing not working at all are calls. It thinks it is calling, says it is calling, but there is no audio feedback for dialing or ringing. The phone part is dead. Don't know why. But, my battery drain is fine, wifi on or off.

I still like the theory, suggested by @EskeRahn, that it is related to cell connectivity, and I don't think it matters much what the network preference is. I don't have the battery drain issue with Lineage 22.2 on my Pro 1, but my Pro1 can no longer make or receive calls. It has a SIM, knows it has a SIM and is fine with texting and data, but can't call. If I put in another SIM, the same thing happens. I guess a test might be for someone to put the phone in airplane mode (you can turn on wifi, but leave the cell connectivity in airplane mode). Maybe my lack of cell connectivity (and I mean t

Remember, the updates are not just what is being added... they are the whole package with the updates integrated. (They don't disturb your settings and data).

If you get the 8GB number, factory reset. I believe that corrects the problem. It happens from time to time, but not often, as I recall. It's always a good idea to check after flashing.

I was curious about the availability of the replacement LCDs (Elephone U Pro display) as I hadn't checked in quite a while. The result is a bit alarming. Aliexpress, which used to be a reliable source (the little shops would run out, but other little shops would pop up with it), now seems to be completely wiped out on these. In fact the only link that came out of searching that still worked was this: https://www.amazon.com/Jaytong-Replacement-Elephone-Pro-Assembly/dp/B0B6362SSK It is double to triple the price it used to be on Aliexpress, and the seller's ratings are not stellar,

Sorry, running a little bit behind this week... 😉 Lineage-22.2-20250602-NIGHTLY-pro1x with May 5th security patch installed smoothly via OTA. MindTheGapps15, and root was maintained.

So I took my pro1 and pro x and switched Sim cards.. This confirmed that, in fact, my Pro 1 is unable to do calls anymore. There was no problem with either sim card in my Pro1x. So, it may be that my good battery performance on the Pro1 is due to the fact that it can't use a SIM. I sort of don't care enough to do anything about it as I do not ever use my Pro1 as a phone. (I rarely use my Pro1x as a phone and it works). This also suggests that, to the degree that it is a LOS 22 problem, it does NOT seem to be a problem with the Pro1x version of LOS 22. Round and round we go... 😉

Well, and this will probably be my last comment on this unless something changes-- I updated both my Pro1 x and Pro1 (in that order) today to the latest OTA updates. On both I downloaded the updates and performed the install and reboot. I also looked around on both to find some settings (the same on both). Otherwise, I just let them sit. Both started out at 85% battery (the max I allow them to charge). 7 Hours later, the pro1x was 73% and the Pro 1 was 75%. I'm going to declare pretty confidently that I don't have the battery drain problem.
