1. After the upgrade Music App which came preloaded in GB 2.3.6 is no longer available in ICS. ( i got app hellobob - member atrix 2)
I purchased this mobile phone because of music clarity & superb beats which were in the music app CMP preloaded in 2.3.6. There were some disadvantages with this player but agianst sound clarity they were nothing.
2. After the upgrade Task manager app is also not available.
3. music player haas been replaced with googles glay music app (google Play) which is totally upsetting, no clarity in the sound, noisy sharp voice, no beats clarity. (nokia mobile which are within 2000rs play better than this.)
4. Unable to control the memory consumed by runnig application,. of 1 GB RAM if you continue install more app phone will start hanging beccause of you are unable to control the running process which are consuming lot of memory. This is big drawback in terms of performance of mobile.
5. No option to above in the phone settings. No of processes shifts to standad every time when you restart the phone. This setting is availble under developer option, i am not sure if this control the running apps.
6. Upon the power button press immediately open up password screen for enterprise users this is sometimes may cause problem if user keeping mobile pocket & get keys preseed automatically, or keys pressed by kids or friends not knowing the password. Additionaly no of attemps remaining is not displaying, earlier used to display the same. This is really big drawback - as entire phone data will be erased including data on SD card.
7. Vibration control features are not available.
There are some more important basic simple phone features in terms of user options ( accessbility) missing in motorola atrix 2 (may be other motorola phones as well) - major drawback - which I shall open another thread to discuss the same. This features I had in my Nokia 6233 which I had purchased 6 years back (might have been designed 7yrs back). That was just an 7 MB ROM mobile. These missing features really making me unhappy with Atrix 2/Motorola.
