Yes! I am having very annoying and ongoing issues with my v20. I got it in October 2016 on TM as soon as it came out and the issues started almost immediately. I had read that the issues were known (battery usage and network/wifi connectivity) but that they were happening since the hardware and OS were brand new. The v20 came out right before the pixel and was the first phone to market with the new Nougat OS. I read that firmware updates were on the way to address the issues, so I muscled though it. But the update(s) have not helped and the problem is worsening. I experience:
- terrible connection speeds in many apps, even if I am showing full or near full LTE signal
- switching from wifi to cellular network sucks, at work I have to be on the wifi as the cellular is non existent (even though I have signal bars showing)
- when switching from wifi to network if I do not put the phone in airplane mode first, it will not connect to the LTE network for a while (minutes)
- Apps that use cellular data are often very slow or hang up and sometimes lock up (forcing me to kill the app)
- Google search bar will do one search and then you change the search but it still pulls up the previous search results
- I do not get some text messages, I have screen shots of my friend's phone with the sent text to me and noting ever comes on my end. This is getting worse and worse. I use the phone for work too and its not acceptable
- Battery life is average at best but when on wifi it flat out blows. From full charge in the morning to 15% or less in under 7 hours
- sound quality on my end is great. I do not often drop calls, no more than other phones i have had, but a lot of people complain that I am hard to hear or choppy.
- I do like a lot of things about the phone. The SD card expansion and the changeable battery are why I got it. I still like that. I like the feel and form factor, for a big phone screen its slim, light, strong, and easy to carry in your pocket
- Great camera especially in good light, forward camera is good too.
I've talked to TM several times both in store and over the phone. I have cleared the app cashe a couple times which helps in the short term, I just did the network reboot which should be nice and painful to input all the PWs again but hopefully helps. I saw a suggestion to turn off the HD, but that was also a selling point for me. I am resisting doing a factory reboot as I put all my apps in folders and that gets all blown apart and I have to spend a few hours redoing it. Any suggestions for getting TM to help more? Maybe a new sim card, but that so many of us are having issues with this phone makes me think its in the firmware/harware.
