From the OP's sig:
Coby Kyros MID7015 (Android 2.1--don't ask!)
Given what it is, I can certainly understand that crashing a lot, been generally unstable, laggy, etc. Think we already discussed this piece of junk in another thread anyway.
Kindle Fire (Cyanogenmod 9 Android 4.0.4 ICS)
ZTE Merit (Z990G, CyanogenMod 7 tacked on stuff)
What's the "tacked on stuff" about? Also are you using a stable version of CM?
, and not a beta, development or nightly build?
The ZTEs should be OK with stock ZTE Android, although the budget phones like the Merit
, can feel laggy, because of slower single-core CPUs and not much system RAM
. Certainly can't compare the ZTE Merit to say an expensive high-performance Samsung Galaxy 3 or iPhone 4S or 5. Can't comment about CM with them. Is the Merit officially supported by CM?
I had a Galaxy S with CM, found that to be very stable, no problems at all.
I've two Android devices myself, with ICS 4.0. A cheapo off-brand device
, and sure enough that crashes, force closes, frequently has to be reset, etc. And a Lenovo phone, and that's extremely stable and very responsive.
