I am very disappointed from the android software on my Evo 4g lte. The other day i discovered that i can't end a held call after i answered the second call. Also i tried to add another call to make a conference call but i received an error says that It can't establish a conference Call. In another incident i was unable to make a conference call between to calls that i didn't initiate. My my question is if there is anyway that we can address those issues to sprint so they can work on finding a way to fix it. By the way as far as i know that htc one x and s don't have those issues, i know that because i checked on the user manual of both devices.

The conference calling limitation is not handset specific. It is due to the underlying IS-41 core network that kept cdmaOne/CDMA2000 compatible with AMPS (analog cellular). As a result, CDMA has enjoyed a substantial coverage advantage in North America. Most people do not require complex conference calling features. If you do, you need to go GSM ecosystem or VoIP.

Thank you AJ for the clarification, i didn't expect that quick answer. Your answer Confirmed my Thoughts that sprint ecosystem doesn't support the Complete function of conference call feature. And what about ending a held call option is it also related to sprint ecosystem or to the software?

    • I wish carriers did spectrum swaps as often as they did in the past. Verizon, AT&T, and T-Mobile could easily swap and fix this issue. AT&T can take the entire PCS A-block giving them a contiguous 15MHz as opposed to the split 10+5 they currently have, Verizon could take both the D and B block and keep the contiguous 20MHz they have now, and T-Mobile could take over the E,F, and C block which would give them a contiguous 30MHz with the G-block. I wouldn't be surprised if Verizon is the only holdout in this because this swap would benefit AT&T and T-Mobile but would leave them in a net neutral position as their 20MHz of PCS is already contiguous.
    • They have the intention, as the equipment they're deploying supports n26. The transaction has not yet happened, T-Mobile is still in control and using the spectrum on some Sprint keep sites.
    • Did they declare their intention to buy band 26 from T-Mobile. I know that they have the option to buy it but do they have the money or the intention to buy it? Are they leasing it right now?
    • Just cycled through here and there's a Sprint Keep Site within range with 25+26+41. 25 is still 10x10, while 41 is the same 10 MHz at the top of the band that I saw at the airport on Friday night. Speeds aren't great, but signal isn't bad, so my guess is that they turned up the power on the site vs. where it was before (B26 is -101 RSRP and I know the site nearest me is gone). Will be downtown for fireworks tonight, so will see how networks perform. I have mmW-enabled VZW and AT&T SIMs to play with.
    • I believe they have made a few attempts, but I don't think there has been a large scale effort so far.
