    Well I have found a partial workaround, skreebl the app that keeps your screen on at angles also has options to control the screen when using the phone. A combination of skreebl and sliding my phone open to make it wake up the first 2 times during a call can work together to make this a useable device for now.

    droidic I don't see how restoring froyo and then putting SS on could fix it, can anyone else confirm it before I waste more time reflashing my NAND for no reason? (or whatever that thing uses)

    edit:

    I should also note that before skreebl, if I slid the phone back closed, it would shut back off, perhaps this info could be key in debugging chevyno1 ?

    edit 2:

    and of course when it would shut back off, it would ignore the power button, it could usually be woken up by slideing open a second time, but after that it was off, until it hit a charger, or battery pull.

    did this software come from a flip phone device? its as if it thinks it needs to be off when its not open, but only when using the phone application...

    I also had a problem similar to this, when I had an incoming call I couldn't answer it at all and had to wait for it to go to voicemail then call them back, however I had changed the ring delay value so not sure if that was the problem but I also had an issue before that call where I could answer but could not even hit the end button to end the call and had to pull the battery
    Another issue I had was another call I could use the end button but after the call my phone went crazy lol...it was extremely laggy, my back soft button wouldn't work, launcherpro wouldn't show home screen it would only jump to screen previews or any previous app I was on and the power button menu would pop up but I couldn't select anything on it but tapping the power button would still turn the screen off and on...I reinstalled the entire rom and kernel again afterwards but haven't had any calls since...I always wipe everything 3 times or more between rom installs even use the partition menu to wipe boot and system 3 times too

    My phone has a bad delay when the phone rings, and I have the setting set to where I can press the power button to end the call, because my screen will not come back on for about 15 seconds after the call ends. I'm running v4.96 with the 1.1ulv. When I set my minimum clock to 550, it works like its supposed to, but with the minimum at 550 it eats the battery pretty quick.

    What is the flash limit of the ROM (Hardware FLASHABLE memory) in these phones? Every ROM has a flash limit. Perhaps some of you guys that have been flashing a lot of different ROMS and kernels, are finally reaching the EOL of their memory chips, and sectors have become unwritable/unreadable.

    It would certainly explain the random issues. I have only been flashing my phone since March, and knock on wood, so far so good.

    Is there actually a limit to how many times you can flash roms? I'm sure we couldn't have flashed as many times as a lot of the devs so is there actually a limit...?

    Yes, there is. From the WIKI:

    Another limitation is that flash memory has a finite number of program-erase cycles (typically written as P/E cycles). Most commercially available flash products are guaranteed to withstand around 100,000 P/E cycles, before the wear begins to deteriorate the integrity of the storage.[8] Micron Technology and Sun Microsystems announced an SLC flash memory chip rated for 1,000,000 P/E cycles on December 17, 2008.[9]
    The guaranteed cycle count may apply only to block zero (as is the case with TSOP NAND parts), or to all blocks (as in NOR). This effect is partially offset in some chip firmware or file system drivers by counting the writes and dynamically remapping blocks in order to spread write operations between sectors; this technique is called wear leveling. Another approach is to perform write verification and remapping to spare sectors in case of write failure, a technique called Bad Block Management (BBM). For portable consumer devices, these wearout management techniques typically extend the life of the flash memory beyond the life of the device itself, and some data loss may be acceptable in these applications. For high reliability data storage, however, it is not advisable to use flash memory that would have to go through a large number of programming cycles. This limitation is meaningless for 'read-only' applications such as thin clients and routers, which are only programmed once or at most a few times during their lifetimes.

    However, the above information being said, I have seen them fail at far less than 100,000 times. Probably in the 1-2000 range. Swap is very hard on NAND memory!

    I wonder how old those wiki figures are. 2 years ago I could easily buy flash memory for my camera that was rated at 200K+ cycles. I would assume that kind of stuff hit phones as well.

    Probably in theory, but in reality, most people do not flash their phones, and they will all outlast the warranty in that case. We here all push our phones to the limit! this is probably why we have to wipe the data/cache 3x times or more in order to make sure it is "clean".

    I bet I have flashed my phone, restored backups, etc at least 200 times since the end of March.

    I would think only the devs would have to worry about that though, I wouldn't think most of us have flashed nearly as many times as someone like Chevy has, and if he hasn't seen any effect then why would this be an issue for us? I think I'm gonna try a fresh download and flashing with the newest kernels and make sure it wasn't a download error or anything...I'll report back later

    If the guys behind ClockWorkMod would add an Advanced tool that actually zeros the partitions, and looks for errors, it would certainly eliminate the speculation behind this. and then we would know for certain.

    Oh btw how could you install a different dialer.apk if needed? (Say the one from 5.2) I know trying to uninstall the current dialer.apk creates a force close loop so can they be switched out?
