Owners of the Galaxy Note 4, Samsung's current flagship phablet, have reported performance issues after updating to the new Android 5.0 Lollipop OS.

Samsung is feverishly preparing for the release of its latest flagship smartphones, the Galaxy S6 and Galaxy S6 Edge. The company has begun preorders at all affiliated carriers in anticipation of the April 10 release date. Both smartphones will be running Android 5.0 Lollipop, the latest Android OS, out of the box.

Additionally, several affiliated retail stores have also started accepting preorders for the new flagships from Samsung.

Meanwhile, many owners of the Samsung Galaxy Note 4 are still waiting to receive the Lollipop software update. Verizon, T-Mobile and U.S. Cellular customers with the smartphone have yet to taste Lollipop, but for those users who have, the taste may not be as sweet as they anticipated.

Sprint released the Android 5.0 Lollipop update to the Galaxy Note 4 in early March, and AT&T rolled it out to its users later in the month, along with the update to the Note 4's predecessor, the Galaxy Note 3. It seems that, while some users are happy with the update and see improvements, particularly in the case of the AT&T rollout, other customers are experiencing issues with the software.

Online forums are buzzing with numerous issues experienced by AT&T Galaxy Note 4 owners including random reboots, forced closing of apps and battery drain problems. The issues are similar to those experienced recently by HTC One M8 users after receiving the Lollipop update. Many of those experiencing problems are being told to perform a factory reset of their phones, which is sometimes effective, but in other cases does not improve things.

While some issues when instituting a major OS upgrade on any device are inevitable, it appears that some of the problems being reported may be due to software issues that need to be sorted out and integrated into a newer version of the update. Verizon began rolling out Android 5.0 Lollipop to the Galaxy S5 in February and then suddenly halted the rollout until proceeding with a new build number just several days ago. While the company has remained mum on the details, it is presumed that software issues with the update necessitated the delay. It's difficult to evaluate the Note 4 situation because some users are having no issues whatsoever since receiving the update and are actually reporting improvements such as increased battery life.
