Moto G Android 4.4 KitKat Problems: For some users, since installing the update of the Android OS, huge battery drop problems have been experienced by a lot of users and Google's only answer is to uninstall applications that use camera particularly Skype.

They said: "Uninstalling Skype may substantially reduce the likelihood of this bug appearing, but I realize Skype is a very important application for many people. Other camera-using applications may trigger this bug as well, but that's been relatively rare. Most applications also do not access the camera when not in the foreground, so they will only trigger issues when actively used."

With Motorola having the strategy of becoming the first company ahead of Samsung, HTC and Sony to have its smartphones equipped with the latest version of Google Android's OS - Android 4.4 KitKat - it may have backfired as problems left and right await users particularly those who had the Moto G, which was the first one to have an upgraded OS.

The Moto G phone was released last year equipped with the Android 4.3 Jelly Bean but was quickly changed to have the KitKat that had upgrades for camera enhancements, interface tweaks, better battery life, and a few other minor changes.

This, however, didn't quite work for the phone company as hundreds of complaints were garnered in a Motorola support site saying that the upgrade was a failure for the users.

According to the complaints users filed, the KitKat upgrade had their phones, as taken from the Motorola Forums:

1. Lose mobile signal
2. Display 'No Sim' icons,
3. Fall into Airplane mode (while not displaying Airplane Icon status)
4. Mobile signal can often be recovered by swapping into and out of Airplane mode.
5. Pop-up errors about being in Airplane mode while attempting to make calls during signal problems.
6. Airplane mode observed in about phone status (while no airplane mode shown on icons)
7. Popup errors - the process "com.android.phone" has stopped
8. Not specific to individual SIM cards - multiple SIMs (cutdown/original confirmed as impacted)
9. Suggestion that it only occurs with mobile data enabled - to be investigated.

At the same time, HTC One users have been experiencing some difficulties as well with the new update and are experiencing battery drain as the main issue for them compared to signal problem with Motorola.

Some users complain about the phone automatically switch
